NE S LETTER


BUREAU OF PLANT QUAP.UNTINE UNITED STATES EPTJ !ENT OF AGRICULTURE IA Ni BOARDD


Number 32 (NOT FOT1 PUBLICATION) August 1, 1933.





ADMINISTRATIVE


The attention of all employees of the Bureau who may have occasion to make field trips into the State of Nebraska is called to the paragraphs quoted below from a recent letter from A. C. Thomas, Manager, Radio Station 17JAG, Norfolk, Nebr., to Donald B. Murphy, c/o Wallace's Farmer, Des Moines, Iowa: Every Sunday afternoon at 2 p.m. we present a farm forum program. This started January 1 and has been devoted to discussing the farmer's
problems, and possibilities of relief. Recently
we have used it to explain the farm relief act.
The period has a Lxeat many farmer listeners all
over the Third Congressional District.

Do you think it would be possible for the Department of Agriculture in sending men into the
field, who are to spend any time in Nebraska, to
write them so they could be in Norfolk Sunday
afternoon so we might use them on this program?

RECENT PATHOLOGICAL INIECEPTIONS OF INTEREST

New disease of conifers.--Diseased leaves of Sciadopitys verticillata from Japan intercepted at Seattle were referred to mycologists in the Bureau of Plant Industry who determined the pathogen as Phom$psis sp. and state that it does not agree with any Phomopsis previously reported as found on conifers.

Citrus canker.--California ports intercept citrus canker more or.gess frri quently in fruit from the Orient, but interceptions of this disease are- rarely set to Washington for determination. A Washington navel orange from Japan intercepted at Seattle was referred to Washington and the presence of citrus canker ves fied by Dr. H. R, Fulton,

Beet rut from Mexico.--Uromyces betae was intercepted at San Ysidro on leaves of mangel-wurzel, the first interception of this rust from Mewico.

Nema interceptions--Nema interceptions for which determinations were received during the month included Aphelenchoides sp'., probably a new species, in stem of decayed sugarcane from Puerto Rico, intercepted at Washington. Other interceptions were Aphelenchoides parietinus in onion from Japan at Philadelphia, it parsnip from Swe a Tire, nd in Stachys sieboldii from Belgium at Philadelphia; Aphalenchus avenae in carrot from Africa at Philadelphia; Tylenchus ditsaci in potatoes from Germany at Corpus Christi and New Orleans, and Tylenchus pratensis in yam from Japan at Baltimore,

Orchid rust.-.Stanhopea sp., an orchid imported from Guatemala and being
grown at Baltimore, Md., was found to be infected with a rust, Uredo nigropunctate

Phomopsis rudis found again.--Phomoysis rud'is (see News Letter for Feb. 193 p. 6) has been found on Laburnum watereri and Colutea kesselringi imported from Hc land and being grown in Ohio.

Root-knot nematode name changed.--The Plant Disease Reporter 17:64-96, June
15, 1933, lists the 855 known hosts of the root-knot nematode and adopts the name Heterodera marioni (Cornu) Gooday for this nema. Since this Bureau follows the usage of the Bureau of Plant Industry for plant pathogens, this name will hereafte be used by this Bureau. It is suggested that the generic name may be changed to Meloidogyne later. Heterodera radicicola and Caconema radicicola are the best known of the various names given this nema.









Correction.--The item headed "Ierbarium material" on page 5 of the July
News Letter was prepared for the June issue but was crowded out and inadvertently
run in July without correcting the reference to "material mentioned elsewhere in this issue" to show that mention was made in the June issue.

COTTON PACKING CAFPIES PIK BOLLWORI

(Reported by W. H. Freeman from the port of New York)

On June 19 a small package of earthenware from Egypt was intercepted in the parcel post. The crockery was packed with about one quarter pound of cotton lint containing one small wad of unginned cotton with seeds. Practically every seed showed damage by pink bollworm, and two living -larvae were found and submitted as an interception. Five dead larvae were also found.

IN THE JU1EN2 TBE INSPECTOR

This phrase is of common occurrence in quarantines and regulations, where it appears in various forms such as, "as the inspector may require", "in the opinion of the inspector", etc. The use of such an expression arises from the practical impossibility of foreseeing in advance and establishing beforehand correct procedure for every situation that is likely to occur. In ,certain fields of quarantine work cases are constantly being met which show such endless variations and widely diversified conditions that it seems more sensible and more fair to the public to handle them with due regard to the accompanying circumstances rather than attempt to fix in advance a complete set of rules which for many individual cases are bound to be either inadequate, or useless, or unnecessarily harsh. With a measure of discretionary power incorporated into the regulations a certain flexibility is provided
for and the actual procedure adopted comes more nearly in accord with the biological necessities in each case.

The term "judgment of the inspector" is not to be construed too literally, however, as denoting merely the ruling of the individual employee. It is rather to be understood as a legal term, mbodying the opinion and decision of the whole Department as an administrative agency. The inspector from this viewpoint is not to be considered as an individual, but a's the agent through whom the purposes of the Department are carried out, by virtue of instructions front the Bureau head, the administrative representative of the Department. The inspector's action must, therefore, be always in line with the policy of the Department and in accordance with instructions, insofar as policy has been established and instructions have been issued.

Where some particular situation falls outside the scope of such fixed policy or instructions do not cover it, the individual judgment of the inspector comes into play, though it must still be recognized that such judgment can in no case be exercised outside the regulations or the act on which those regulations are based. On such occasions the inspector becomes for the time being the Department itself in the matter of exercising judgment.

It is thus anparent that only in unforeseen situations, where instructions






-5

or other guiding statements are inadequate, or where the exigencies of the case preclude reference of the matter to the Bureau for instructions, does the personal judgment of the individual inspector come to be properly exercised. In all such cases, and they are by no means infrequent, the phrase takes on its literal mean.ingo






DOYTSTIC PLANT QUARAI1T ES

Information on court cases having a bearing on plant quarantine or similar laws is being collected for the purpose of providing Federal and State plant quarantine officers with decisions and opinions of general interest. The work is being done in response to a request of the National Plant Board, expressed at its meeting last March, that periodic synopses of such cases be assembled and distributed by this Bureau. Information as to two cases has previously been sent oui

New reports on the Dutch elm disease by the Bureau of Plant Industry show
that infection has been discovered on at least nine American elm trees at Maplewoo South Orange, and East Orange, N. J. One additional diseased elm has been locate at Cleveland, Ohio# ITo nursery has been found infected nor has any connection ye been established between the various diseased trees and any nursery.

TRANSIT INSPECTION

Empty refrigerator cars arriving at Chicago from the Japanese beetle infested areas are being checked by transit inspectors to insure their being swept and cleaned of all rubbish which may carry the beetle, as provided by quarantine regulations.

Shipments of soft-shelled crabs packed in cedar boughs and parts of. other plants that should have been certified under Japanese beetle quarantine regulations were recently noted at Philadelphia, coming from the Eastern Shore of Maryland, Grape leaves, packed in and saturated with salt, were found by a transit inspector at New York to have been consigned from the Atlantic to the Pacific Coast. These shipments were reported to the field office in order that the shippers might be located and arrangements rade for certification of future similar shipments.

The recent interception of a greenhouse-grown oleander shipped by a New
England florist without gipsy-moth certification resulted in considerable correspondence with the shipper and the carrier in explaining the certification requirements. Under the present edition of tbe regulations, greenhouse-grown cut flowers of woody plants may be shipped without certification when the container is marked to show plainly that the material was greenhouse grown. This exemption does not apply, however, to entire plants, such as oleander, as such plants are
occasionally set out of doors and may have egg masses attached to them while in the open.









WHITE-PINE BLISTER RUST

The. inspection of pine-growing nurseries in Maryland and Virginia is now
under way, and it is found that Ribes on these areas are much scarcer, and the problem of Pibes eradication much simpler, than is the case in New England. Bureau inspectors working in cooperation with State authorities of Iowa and Minnesota report, on the other hand, difficulty in accomplishing complete eradication around the pine nurseries in those States. Crews had to cover the territory around some
nurseries several tires before the -%ork was completed to the extent required. Several -nurseries are planning on changing locations in order to provide areas where Ribes are easier tq eradicate.

Favorable action on 6 applications for pine-chipping perraits has thus far
been taken for the fiscal year 1934. Two of the nurseries are located in Virginia, 1 in New York, and 3 in New England. Four of the permittees were found. to be growing pines in Ribes-free zones, and were therefore authorized to ship, while the premises of 2 others were tentatively approved, subject to reapplication and inspection prior to shipping. About 30 other applications are under consideration. The joint certification tag described on page 8 of the June News Letter will be employed in the case of nurseries located in areas regulated on account of the gipsy moth and Japanese beetle.

NArCISSUS BULE PESTS

The Bureau is compelled, under the limitation of funds available for the
present fiscal year, to withdraw all assistance heretofore given the States in the inspection for narcissus bulb pests. While there has never been specific Federal appropriation fbr the inspection of narcissus, employees on other projects have been able, in the past, to give some incidental aid to State inspectors in the diagnosis of pests and in maintaining high standards of treatment and practice. Notice has recently been sent by the Chief of the Bureau to officers of these various States that it will not be possible to render any such assistance this year.

Supplementary administrative instructions relating to narcissus treatment
and pest suppression have been issued by the Bureau as circular BPR-353. The new circular authorizes the use of the vapor-heat treatment for bulb flies in lieu of the hot-water treatment, if desired, It also changes the presoaking requirement
by reducing the length of time dry bulbs are required to remain in cold water, from 12 hours to 2 hours. A number of interpretations and slight modifications of the administrative instructions concerning narcissus inspection issued last year are
includtled.

BLACK STEM1 RUST

The checking of nurseries under the black stem rust quarantine was begun about the middle of July by L. 1. Ames, of the Zureau of Plant Industry, who is working in cooperation with this Bureau. NurserymIen engaged in.the shipping of barberry and iMahonia plants to or between the 13 barberry eradication States of the Middle West apply in the spring for inspection of their premises. If they









are found to be handling only rust-resistant species and varieties, permits are issued which authorize them to nmke such shipments. No such permits are, however required for the Japanese barberry, which is immune to the disease.

PHONY PEACH DISEASE

Under the new plan of coopoerating with the States in preventing the spread of the phony peach disease, branch headquarters have been established at Texarkana Tbx., and a Bureau inspector will work out from this point, going with the nursery inspectors over the environs of peach-growing nurseries. He will work primarily in Arkansas, Louisiana, and Texas. Atlanta is continued as headquarters for two other inspectors now working similarly with the State inspectors of Georgia, Alabama, and Tennessee. They expect to reach North Carolina, South Carolina, Mississippi, and Illinois a little later.

State restrictions with reference to the phony peach disease and the peach borer have been passed recently by Mississippi, Georgia Arkansas, and Delaware, following the revocation of Federal quarantine no* 67.





DATE SCALM ERADICATION

During the month of June a snall planting of palms on the property of E, E Forrester, in the Imperial Valley, was inspected for the first time since Februar, 1932, although located in the infested area and having shown scale in 1930. The: were 13 palms in this planting, the tallest about 15 feet to the bud. Water fro3 the main irrigation canal was allowed to flood this and adjoining properties at about a 7-foot level for several months. About 6 feet of silt was deposited, leveling the land. Incidentally the time necessary for inspection of the palms was greatly reduced. Water reached the buds of 9 of the palms, all of which die The 4 whose buds were above the water level survived and seera to be doing very we:

This changing of the lana level has been noticed on several previous occasions when digging out worthless palms along ditch banks. Sometimes it has been necessary to remove about 5 feet of soil before reaching the base of the trunk#

No new infested properties were found during the past fiscal year. The last new infested property in the Imperial Valley was found in June 1932, in the Coachella Valley in May 1930, and in Arizona in April 1930. The number of infested palms found has decreased from year to year as follows: Fiscal year 1929, 1,590; fiscal year 1930, 621; fiscal year 1931, 232; fiscal year 1932, 59; fiscal year 1933, 8.









JAPAESE B-ETLE A1D EUROEAIT CORN BOPER

Exclusive Japanese Beetle Work

S Reports received from transit inspectors during May largely served to elimi, nate most instances of the use of dual certificates on shipments certified under the gipsy moth Lnd Japanese beetle quarantines. All shipments observed in transit beating two certificates were reported to the inspectors responsible for issuance of the certificates. Rubber stamps for use of inspectors whose duties include the certification of material under both quarantines have been distributed to all employees authorized to perform this joint service. The stamped certificate is slightly less than 1-1/2 by 2 inches in size. In addition to the Department and Bureau heading, it contains the words "quarantines No. 45,48" and "Issued to ." A changeable date stamp occupies the center position on the stamp. Each stamp bears a different number prefixed by "Certified by Inspector No." A line headed
"Destination" is also provided for use when there is a destination limitation such as that imposed by the white pine blister rust quarantine. Final lines state "Void after five days" and "Certificate not transferable." After the "Quarantines No. 45,48" may be added any other quarantine number for which the contents of the package are certified. If certification for only the two quarantines is involved, a line or check is placed after the "48". Use of the stamped certificate will not supplant entirely the issuance of the regular certificates to classified esJablishments. Many classified establishments in uninfested sections of the regulated zone are furnished with monthly supplies of Japanese beetle certificates. Use of these by such establishments will continue. In all other instances, inspectors of the two projects are authorized to use the joint certificate stamp to fulfill the requirements of both quarantines. Since the joint certificate is stamped directly on the shipping package, presence of the inspector is required in connection with the affixing of this type of certification.

Approach of the seasonal quarantine on fruits and vegetables required the formulation of a definition of "commercially packed apples". A provision of one of the quarantine regulations exempts "commercially packed shipments of apples in any quantity". State officials of each State included within the regulated zone were requested to submit such State laws or interpretations as might assist in formulating a uniform definition to conform to existing State standards. While the State requirements in many instances parallel the Federal standards or grades, the standard requirements for grading and packinC of apples are not uniform in the 11 States involved. The intent of the regulation as originally written was to exempt apples which have been subjected to a grading process or such other intermediate handling between picking and packing as would eliminate beetle infestation. As finally defined in BPQ-352, issued June 26, the term "commercially packed apples" includes all a ples in closed barrels, boxes, or baskets, of sizes and types customarily used in the apple trade; and apples in open packages when such apples have been graded in accordance with the official standards for apples promulgated
by the United States De)artnent of Agriculture or in accordance with any official grades authorized by the State in which the a ples were grown and when the containers are marked with such Grade. The so-called "unclassified" grade is not, however, considered a gtade within the ieaninc of this definition,, and apples in open packages so marked are not considered commercially packed.









Mimeographed sheets listing all inspection centers established on June 15
for the inspection and certification of quarantined fruits and vegetables were dia tributed by road inspectors to truckers passing the vehicular inspection stations just prior to the effective date of this year's suxmner quarantine. Twenty-eight inspection centers are required to supply the demand for this type of service. These are located in the following produce growing and marketing districts: Norfolk, Va.; W7ashington, D.C. (two inspection points); Baltimore, Hagerstown, and Cumberland, Mid.; Wilmington, Dover, Milford, Georgetown, Bridgeville, Wyoming, and Woodside, Del.; Philadelphia, Pittsburgh, and Altoona, Pa.; Cedarville, Glassboro, Trenton, Rutherfor, Bridgeton, and Hanaonton, N. J.; New York. City, Syracuse, and Albany, I. Y.; New Haven, Conn.; and Boston ard Springfield, Mass. Hours of service conform to local shipping requirements. In Baltimore, 24-hour service is available from 1Monday to Friday. Decrease in the demand for inspection in Philadelphia permits operation of the platform from 4 a.m. to 8 p.m. Monday to Friday and 4 a.m. to noon Saturday. In, previous years the Philadelphia platform has maintained 24-hour service on all days except Saturdays and.Sundays. The majority of the centers supply all inspection required by operating during the usual hours of 8 a.m. to 5 p.m. Monday to TFriday, and 8 a.m. to noon Saturday.

Activities of a Japanese beetle road inspector were given a prominent part in a fUll-page colored comic strip appearing in the New York Herald Tribune and other papers syndicating the same cartoon on Sunday, June 25. H. T. Webster, in his strip -entitled "The Timid Soul", portrayed Caspar approaching a Japanese beetle quarantine station in his automobile and being flagged by a uniformed inspector. The inspector inquired whether or not any fruit or vegetables were being transported. After replying that he had none, Caspar was told to proceed. The next picture depicts Caspar approaching a detour. Then follows his travels over an unusually bumpy road. After proceeding over any obstacles, an interior view of the car shows Caspar observing a'-strange insect on the windshield of the car. The automobile is then shown retracing the detour. The final picture shows Caspa back at the road station post where he infor-rs the inspector that he has found a strange insect in his car c.d since he did not know whether or not it was a beetle he brought it back. The inspector registers amazement. The title strip shows Caspar and his wife in their coupe with the windows closed. His wife wishes the windows opened but the Timid Soul says he would rather not open them since he is afraid a Japanese beetle or a Florida fruit fly will get in.

Imposition on June 1, 1933, of a fine of t50 for a violating of the plant quarantine act concluded the first proceedings instituted in the Western District of New York under the Japanese beetle quarantine. One July 20, 1932, Henry Rudner, of Rochester, N. Y., was stopped at the quarantine vehicular station at But tonwood, Pa., at which time he was trucking 70 bushels of uncertified apples from Baltimore, IvId., to Rochester, N. Y. He was given an opportunity to return to Williamsport, Pa., for inspection and certification of his fruit. He refused to return. Instead he proceeded to his destination with the contraband. Complaint against the violator was filed before United States Coimissioner Cyrus W. Phillips in .Rochester. The defendant- was not apprehended until November 10. He was arraigned before the Co'issioner end released under bond in the sum of $500. The case was held over for the Iay term of court in Bochester. On May 18 last the defendant pleaded guilty and the fine was irimposed on June 1.

In additioh to trap control l rork undertaken in Haryland in cooperation with the State Horticultural De~ie n~ cooperative operation of trapd is being carried on in Clayton, Dover, MIiddletpo~n, Syrna, Milfard, and WVyoming, Del. Th .latter State-owned traps were placed ad are being tended by Delaware inspectors Working
from the Dover. district office, Last year's trapping demonstrations in southern New Jersey are being repe ted' with modifications by E. S. Rex, of the New Jersey Department of Agriculture. .This year, 1,000 of the State-operated traps are equipped with containers holding approximately 10 gallons of beetles. All traps are baited with liquid bait. In addition to the recommended geraniol-eugenol mixture, the New Jersey bait contains a waall quantity of plienyl ethyl alcohol. Prior to distribution of the South..Jersey traps, a survey of larval population in the trapped sections was made by New Jersey employees in cooperation with the Japanese beetle research laboratory of the Bureau of Entomology.

One new article of Merchandise sold for the first time this season as a
means of controlling beetle injury, consists of a package of small, perforated cellophane envelopes. These envelopes are designed for placing over rose blooms to prevent beetle feeding as the buds unfold. Thorough spraying of rose foliage with lead oleate coated lead arsenate does not protect the expanding bloom, since the opening flower cannot be kept covered with a film of the poison. Consequently the flower is attacked as soon as the petals appear. It is not unusual for owners of choice roses to protect a few rose bushes by covering the same with mosquito netting, Use of the cellophane envelopes is intended to supplement foliage spraying, and to protect the flowers until their cutting. The cellophane protectors first were advertised by one of the Philadelphia departiment stores.

Placement of traps in 54 towns and cities in South Carolina was completed
by June 27. Set-up crews then moved to North Carolina. Tran routes were established in 53 towns and'e cities in North Carolina byr the end of June. Trap distribution in 8 North Carolina commuhities remained for completion in July. Set-up crews also completed during June their work in Blacksburg, Emporia, Franklin, and Smithfield, Va. This was only the beginning of the establishment of trap routes in Virginia. Traps were set durinL the month in 21 towns and cities in the nonregulated territory of lHaryland. Trapping for control within the regulated zone began during the last half of June in Washington, D. C., -Alexandria, Va., Delmar, Del*, and 33 hryland communities,

After revision to conform to the latest practices, instructions to trap inspectors were mimeographed and asseribled in booklet form for ready reference. Boxes containing sufficient trap inspector's supplies and forms for use during a 30-day trapping program were also prepared. Instructions to road inspectors were similarly revised and a set issued to each inspector stationed at the road stations. Each temporary employee is also supplied with a manual containing instructions regarding procedure to be followed in case of a motor vehicle accident or accident inv61ving personal injury. This latter manual also lists all Government medical facilities in the States in which Japanese beetle quarantine activities or outside tra-pping activities are performed.

Tabulation of data pertaining to treated nursery plots and heeling-in area analyzed early in the spring by the Toxological Division shows that 771,656 square


LIBRARY









feet of heeling-in area and 4,954,497 square feet of nursery plots containing gro] ing plants, or a total area of 131.5 acres, was sampled and analyzed for lead ars nate content. Of the areas analyzed, 358,023 square feet of heeling-in area and 3,000,248 square feet of nursery area required retreatment with varying amounts o arsenate of lead. The surface area requiring retreatment is approximately 59 per cent of the total analyzed. During May and June, 51.1 acres of nursery plots and 7.2 acres of heeling-in area were retreated with sufficient lead arsenate to brin the concentration up to the required 1,500 pounds per acre.

District supervisors conferred at the Harrisburg headquarters for the first time on June 2. Considerable time was given to a discussion of several new phase of enforcement of the smmer quarantine on fruits and vegetables. Personnel mat. ters in connection with nursery and greenhouse scouting and farm products inspection were talked over, and the necessity emphasized for employment of only a
minimum temporary force and elimination of all motor vehicles possible.

Visitors to the storage warehouse of the project at the General Depot of the U. So Army at New Cumberlands Pas, usually are driven the length of the six bays in an automobile or else ride bicycles during the inspection trip. The ware house is 840 feet, or 0.16 mile long, with a round trip, through one lane of fire doors and back the other lane, of approximately one third of a mile.

Scouting of classified nursery and greenhouse establishments and adjacent premises for a radius of 1,000 feet began in Virginia and Mahryland on June 12 and in Delaware on June 15. Similar activities in New Jersey and Pennsylvania will get under way on July 1, and on later dates in the more northern States in the regulated zoned

Community spraying with coated arsenate of lead in cooperation with the
Maryland State Horticultural Department was performed in Laurel, Elkton, and Colgate during June. The spray was applied by means of two 600-gallon capacity Fitzhenry-Guptill high-pressure sprayers. Truck drivers paid by the Bureau operated the sprayer trucks. Hosemen, nozzlemen, and crew foremen were paid from
Maryland funds. Agent We F, Walsh, from the Harrisburg headquarters, supervised the work. Dro G. S9 Langford, of the Mryland Department, made frequent visits to the scenes of operations. Characteristics of the three localities sprayed varie( in each instance. In Laurel the spraying was in a distinctly urban community, with many shade and ornamental trees. Premises sprayed were in general well kep and had plantings of flowers and ornamental shrubs. An ordinary orchard nozzle was effective in reaching most of the foliage covered. A short Worthley nozzle was used for some larger trees. Care was necessary to keep the spray drift from houses. The lead oleate-lead arsenate spray was applied at the rate of 9 pounds of the paste to 100 gallons of water, making 54 pounds of the insecticide to one tankful of water. ater was obtained at the city pumping station in Laurel. In each of the three communities sprayed, warning placards were tacked in conspicuous places in the localities to be sprayed before the crews began their work, Scarcely any difficulty was experienced with the persons occupying the sprayed premises. The work was largely welcomed as an attempt to control an annoying pei Three laborers were used in each crew to drag hose. The hoseman nearest the noi. zle acted as crew foreman and made the tree and shrub counts with a hand counter









Each truck carried 1,000 feet of either 1/2 inch or 3/4 inch high-pressure hose, but an average of only 250 feet was used in the built-up communities. The heaviest infestation of the three is in a woodland section north of Elkton. In addition to low wild Growth, a number of tall trees were sprayed in this locality. Long and short Worthley nozzles were used exclusively in this woodland section. The infestation borders several small streams, from which water was pumped directly into the tanks. Two bridges were not strong enough to carry the weight 6f the loaded trucks. It was therefore necessary to adjust the work of the sprayers so that they did not need to pass over the weakened structures in going to and from operations. FoliaSe conditions in Colgate offer somewhat of a combination of urban plantings and woodland area, The infestation extends for a short distance back from astern Avenue and North Point Road in surburban Baltimore. Dwellings are of the small, frame bungalow type, with snall yards and few larns or extensive flower or shrubbery plantings. Beyond the dwellings are niuierous anall trees and considerable thick first growth. In spraying all foliage encountered, it was necessary to pull hose throuJgh thic':ets, among which considerable poison ivy grows. The men were also bothered by chiggers. Tron Colgate it was necessary to drive the trucks several miles to a Baltiiore Cit- fire station to obtain water from a hydrant operated by a paid fireman. In Laurel and Elkton all laborers were hired through the local welfare committee or a municipal official. Nozzlemen hired in Laurel stayed with the outfits in Zlkton and Colgate. At the conclusion of the spraying in each community, anall cages of perforated metal each containing a small jar of gerandOl-eugenol mixture, equipped with rick for volatilizing the liquid, were hung.at the rate of four or five per property in grape arbors, rose bushes, and other preferred food plants. In Erie, Pa., last year the spray mixture applied contained geraniol and syroline for the purpose of attracting the beetles to the sprayed foliage. Frequent applications of the attractant were necessary throughout the season. In iarylainid communities sprayed, the cages of bait will volatilize their attractive odor during the entire period the adult beetle is active. Spraying in Laurel was performed from June 3 to 15, in Elkton from June 19 to 25, -nd in Colgate front June 27 to July 2. Coated lead arsenate used in these respective cconunities totalled 2,295 pounds, 4,170 pounds, mnd 864 pounds. In Laurel there verc sprayed a proximately 11,500 trees and 2,500 shrubs plus a strip of weed and vine growth two fifths ofa nile long and averaging 30 feet wide alonr the D. L 0. railroad at the Lourel race track. Counts were impnracticable of the individual trees and shrubs sprayed in the woodland section north of Elkton. In addition to 5-1/8 acres of woodland, there were 011 trees and 738 shrubs sprayed in Colgate. Trans operated in two of these localities during the summer of 1932 caught 182 beetles in Laurel, and 54,o44 in Colgate. Operation of traps in all three communities began this year the last week in June.

Corn 3orer Activities

Only three prosecution were necessary in concluding enforcement by the State of Connecticut of th"icir co .pulsory corn borer clean-up campaign, Two of these actions resulted from failure of farmers to clo alnd burn cornstalks in compliance with orders issued b- the StaEte inspectors.

During June, inspection and certificatioal continued of articles requiring
Federal certification under State 2uronean corn borer orders for movement into the





-l13


States of Arizona, California, Colorado, Georgia, Louisiana, Nevada, Oregon, and Utah. Eleven inspectors devoted full time to this work A number of others performed some Japanese beetle quarantine inspection work in connection with their corn borer inspection visits. This combined work was compensated for by an equal
amount of corn borer inspection performed by the regular Japanese beetle inspectio corps. The greatest demands for Federal corn borer certification service were in the New Jersey, Long Island, and Boston areas. To and including the month of Jun approximately 3,500 shipments were certified for movement to the States accepting only Federal certification. In view of, the general business conditions in the nursery trade, this quantity of stock moving to eight rather distant States constitutes quite an item in keeping open the regular channels of trade, aid offers
somewhat of a marginal outlet for stock which without Federal inspection would be prohibited movement.




YICAN FRUIT FLY

The greater part of the month was occupied in completing the application of poison spray which was started May 22. A rainy spell of four days set the work back after it had gotten off to an excellent start. With this one exception the weather remained ideal, and since the growers as a whole had no pressing routine
jobs confronting them, the spraying moved alonS rapidly. A number of outlying groves of young trees which experience has sho-n are not likely to harbor an infestation were omitted from this a-,-olication. However, 3,875,075 trees or approximately 55,000 acres of bearing groves were sprayed. A total of 21,240 gallons of molasses and 1,059 gallons of nicotine were used. Five hundred knapsack
sprayers were used by ap?roxinmtely 7,500 individuals in applying the Sprays 'In Qdf dition to the knapsack sprayers, a few of the growers preferred to use their powesprayers.

The set-up for the distribution of the material was much the sam as in
previous applications. Where only muall quantities of molasses and nicotine were I required, delivery was made at the grove by the inspectors. Owners of large plantings called at the distribution depot for the material. Each inspector was assigned certain roads or areas and had from 15 to 20 knapsack sprayers. It was his duty to contact the growers of his area, make arrangements for the spraying of the groves, deliver the material and the sprayer, supervise the application of the spray and pick up the sprayer when the spraying was completed and deliver it to the next grower who was ready to start. It was found that the most effective wor could be done from about 6 to 9 p.m. when most of the growers could be found attheir homes.

In addition to the supervising done by the district inspectors three inspec t tors were assigned full time to this duty. Considering the large number of individuals applying the poison it was found that an exceptionally good application had been made. Abandoned and absentee-owned groves constituted a difficult prob- W lem. The spraying of these properties was accomplished by various methods. In some instances neighboring owners -tere prevailed upon to spray then for their own protection. In other cases civic organizations finunished the labor. 1Iunicipal







governments furnished labor in a number of instances. ,

Upon completion of the spraying, the equipment was gathered up and, after being cleaned, was stored in the warehouse at Harlingen. Surplus molasses was barreled and stored at HIarlingen and Mission, while the nicotine remaining was stored at the warehouse in Harlingen.

Trapping operations were resumed As the spraying was completed in the
various districts. Since most of the inspectors were on legislative furlough during the latter part of the month this vork did not get into full swing during June. It is expected that about 6,000 traps will be in operation ~uring July,

Three adult fruit flies were taken in traps in :atamoros during June. Mangoes reaching the market, particularly t-ose from the State of Michoacan, were found to be heavily infested. During the month. 5,214 larvae and pupae were taken from mangoes from that State. This does not include the larvae from 11 boxes of this fruit tbat were confiscated and destroyed without inspection.

Following the arrival of so much infested fruit and the taking of the 3
adults it was deemed advisable to give all trees in the city an application of nicotine spray. This work was accordingly started during the latter part of the month,




PINTK BOLL01i1

The main activity on the pink-bollworm project during the month was in connection with trap plats of cotton instituted as one of the measures to reduce the heavy infestation of pink bollworm in the Big Bend area of Texas. Blooms have now appeared on all of the 67 plats and infestation has been found in 52 of these plats. In order to arrive at the results being accomplished b3fthe trap-planting program, plans were made to examine blooms from local field cotton for comparative infestation, this to be carried out by inspection of an-equel number 'of rosetted blooms from the plats and the nearest cotton fields. The field cotton was bloomihg sufficiently by the last week in June to begin these comparative examinations. Blooms collected from 37 fields disclosed that 14 of the fields were infested, while blooms from 37 adjacent plats showed 24 of the plants to be infested. From the 14 infested fields 27 pink bollworis were taken, and the 14 adjacent plats yielded 46 pink bollworms. The following week infestation counts were made in 50 nearby fields, 26 of which were found to be infested, yielding 80 pink bollworms, while 346 pink bollworms were taken from the blooms of adjacent plats.
While it is early to draw conclusions as to the ultimate benefit of the traps, the above readings indicate that the advanced trap plantings are more attractive
to the mroths than field cotton.

It may be of soie interest to note that at Castolon, in Brewster County, where only a small isolated cotton acreage is grown and it was impracticable to carry out the special program, 21 rosetted blooms -7ere gathered from one half acre of cotton, from Thich 19 pink boll-orns were removed. It will be recalled that Brewater County was a noncotton zone for the season of 1928.

In the Salt River Yalley of Arizona a small amount of field inspection was I made in the 1933 crop, Some 800 squares and 750 bolls were collected from the Ping field at Laveen and examined, with negative results, It will be remembered that this was one of the last fields to be found infested in that district, no infestation having been found in the area since the 1931 crop.

In Florida the clean-up program of wild cotton on Key Largo was completed at the close of June. There was considerably less wild cotton on the extreme upper end than on the remainder of Key Largo. There was a very heavy distribution on Sound Points which is actually a separate island but at the time of the origins survey was thought to be a part of Key Largo. During the month 50 acres were cleaned; from which 20,735 mature and 5,925 seedling plants were removed, and of this amount 15,365 mature and 4,355 seedling plants covered 40 acres on Sound Point. In addition to the above, 147 domestic dooryard cotton plants were remove from 21 different locations in Dade County, and a total of 240 bolls examined fror these plants gave negative results.

Laboratory inspection has been continued throughout the month. At the
Alpine and El Paso offices seed samples were examined, these samples originating in the States of Arkansas, Mississippi, Missouri, and Tennessee. At the San Antonio laboratory and the various field stations green bolls and bollies were examined. No specimens of the pink bollworm were found in any of the material inspected. In addition to boll examination at Miami, a daily collection and inspection of blooms from the plat cotton at Chapman field was continued, with negative results, throughout the nonthq

The working model of the small gin-trash machine, mentioned in last month't \ews Letter, has been completed and tested out satisfactorily, Some 8 or 10 of these will be available for use at the opening of the gin-trash-inspection season in areas of limited cotton production. These little machines combine the essential principles of the big machine; they have a drum 2 feet in length and approx mately 2 feet in diameter. The machine is so adjusted that when turned too fast the material adheres to the circumference of the drum and stops feeding;- otherwise the worms present in the trash would be picked up and discharged through the suction fan and lost. As stated in the last News Letter, the machine is light enough to be handled by one man, and it will undoubtedly prove a valuable additio) to our inspection equipment. It will enable us to perform efficient and economical inspection in certain areas not heretofore practicable.




PREVENTING SPREAD OF MOTHS

Spraying was carried on in the Connecticut and Massachusetts section of th' barrier zone during the month, a total of 15 sprayer machines being in use. Except for occasional days when there were high winds and some local showers, the weather throughout the month was hot and dry, making ideal conditions for spraying operations. The dry weather, however, brought about a shortage of water in









many aaal1 streams and brooks which were being used to furnish water to mix arse-. nate of, lead spray solution, and because of this it was often necessary to move the sprayer trucks to new locations or haul water from a considerable distance. The two tractors transferred to this project from the Corn Borer-Japanese Beetle activity earlier in the season proved valuable in hauling sprayers over rough mountain roads to points more accessible to areas where spraying was to be donducted. During periods when the foliage was too wet to hold the spray, the men were employed in laying new hose lines and doing rough cleaning work in the immediate vicinity of infestations where spraying was being done. By the time spraying ias completed at the end of the month, more than 1,900 acres had been sprayed, a totai of 38 tons of arsenate of lead and 1,800 gallons of fish oil having been used.

In the Pennsylvania area weather conditions were also excellent for spraying, very little time being lost on account of rain or wet foliage. A total of 26 sprayers were in operation during the month. Although considerable difficulty was at first experienced in training local men to properly hold the spray nozzle, by diligent effort the Federal employees supervising this work taught a sufficient number of them to do this difficult task in a satisfactory manner. This type of spra!ying was ner to them and they therefore- could not et first understand why the solid stream should not be turned directly onto the foliage rather than to hold it in such a manner as to allow the mist spray to drift onto the foliage. It was also difficult to get these men to move the nozzle as rapidly as they should to provent waste and secure the most satisfactory results. They apparently did not realize the volume of material passing through the tips such as are used in solid-strean spraying. Most of the difficulties were straightened out during the first week or 10 days and the nozzlemen, considering their limited experience in solid-stream spraying, performed very good work. To July 1, 2,800 acres of woodland, including the cut-over area, and 5,700 isolated trees had been sprayed. In addition to this work, trees, shrubs, vines, etc., were sprayed on 4,800 properties in residential sections within the heavily infested area. Tore than 48 tons of arsenate of lead and 1,900 gallons of fish oil were used up to the first of July# Spraying will be continued in the Pennsylvania area for about one t7eek in July.

Although it was feared that cattle and goats might be poisoned because of rnegligence on t1-te part of the o-tners in per. itting them to graze in the sprayed area after being warned several tiues of the danger in allowing them to do so) no report has as yet been received indicating that any of these animals have been affected. There was a total of 38 properties for which owners or tenants refused to sign sprayU eiilts. After being served with a State notice, these properties were sprayed under the direction of a full time employee of the Pennsylvania Departrient of Agriculture.

When the foliage was too wet for spraying, the iren patrolled the burlap bands attached to trees in the infested area and killed gipsy moth larvae found hidden beneath them. To and including June 30, a total of 45,561 larvae had been killed under these bands.

Very little serious mechanical trouble was oncmintered with the spraying equipment anywhere in the field this season, an. such as did arise was quickly





-17


remedied by mechanics with service trucks detailed especially for this work. Service trucks made daily visits to every spraying machine and corrected any troubles reported by the operators.

The spraying program in New Jersey was completed by the middle of June, an area of 60 acres of woodland around the infestation in Mendham Township having been sprayed. Upon completion of this work the sprayer loaned by this project to the State was returned to Wilkes-Barre. A check-up was made of the tanglefoot I bands after spraying was finished, and no living gipsy moth larvae were found. Arrangements have been completed for placing assembling cages in New Jersey. This office has furnished the State of New Jersey with 850 assembling cages together with attrahent and other material necessary for the work. The cages will be put up and patrolled by employees of the State of New Jersey. It is planned.to place cages in Mendham and Randolph and a group of townships surrounding them to check up on the scouting and treatment work carried on during the fiscal year 1935, The infested area will also be rescouted during the fiscal year 1934.

Preparations for the assembling cage work which is to be carried on in July were well under way by the end of June. The substation at Middleboro, Mass., on
Cape Cod, where bait materials are obtained, and where dollections of various stages of the gipsy, brown-tail, and satin moths are mounted for specimens, was opened and preliminary work started. Considerable scouting has been done for sizable gipsy moth infestations at which large collections of female pupae may be made. It is planned during July to put up assembling cages in 53 townships in and surrounding the known infested area in Pennsylvania. In the barrier zone in New England and in the area directly to the east of the zone, it is planned to place assembling cages in 87 towns. As mentioned above, assembling cages and material have already been furnished to the State of NHew Jersey. In accordance with a request from the Canadian Departmrient of Agriculture, this office has furnished them with 25 assembling cages. These are to be put out in Canada along the international border, as was done last ykar.

At this season of the year when both gipsy and brown-tail moths are in the
larval stage, inspectors examining shipments prior to certification may find larvae of one or the other on almost any type of materials, sometimes where least expected In illustration of this, a report has been received from the district inspector of the Concord, TN. H., district that he found a brown-tail caterpillar on a consignnent of monumental granite being shipped from Concord to a destination in Iowa.

Although there is a growing tendency toward moving the various. types of
quarantined products by truck instead of by freight, such movement is commonly co fined to distances within a comparatively few hundred miles of point of origin. Rapid transportation between exact point of origin and exact destination, avoiding
the necessity of movement to and from railroad shipping points, is a factor that has decided the choice of trucks over freight. For long distance moving, however, usually such materials are shi pped through railroad channels. Occasionally, a shipment is moved for a long distance by truck because of unusual circumstances surrounding the shipment in question. Recently, a large and valuable ornamental evergreen was shipped by truck fron Connecticut to a point in Ohio, a distance of








over 800 miles. The tree with ball of earth weighed about two tons and as it was particularly valuable it was decided to have it reach destination with as little delay as possible. It could be transported by truck much more rapidly than by freight, and also there was no possibility that it would be injured by heating, a condition to which it might have been exposed if shipped in a freight car.

A suary of the survey of brown-tail moth distribution which was carried on
by employees of this project during the -inter and spring, together with reports from State officials, indicates there has been a marked increase in the infestation in New -ngland as compared with last year. This is based on the number of browntail moth webs cut and reported during the winter of 1932-33. Over 1,127,000 hibernating webs were cut and destroyed in New Hampshire and Hassachusetts. No record is available of the webs that were cut in the State of kaine. There was a material spread of this insect beyond the quarantine line in Haine and Tewl Hampshire, even reaching into five tomwns along the Connecticut River in the State of Vermont. In Maine, 20 towns beyond the quarantine line were found infested, and in New Hampshire 18 towns beyond the quarantine line were found infested. In Massachusetts, Rhode Island, and Connecticut, no infestations were found in towns outside of the quarantine line.

For the oast few months considerable time has been given at this office to plans in connection with the gipsy moth work which might be done as a part of the Emergency Conservation Reforestation program. On April 1, S. S. Crossman, of this office, was placed in charge of this Bureau's activities with relation to the gipsy moth part of the emergency program. The reforestation work was organized so quickly and in such an extensive way that it has been difficult to plan the work and procedure, and some readjustment has been necessary.

The object of the Eraergency Conservation Gipsy Mioth work east of the barrier zone is to find and destroy the gipsy moth infestations that are present between the barrier zone and the Connecticut River, This will protect the barrier zone and aid materially in preventing the westward spread of this insect. It is hoped to use approximately 1,000 men from 9 emergency conservation work camps situated between the barrier zone and the Connecticut River. Four camps are located in Connecticut, four in Massachusetts, and one in Vermont. The use of 100 men has been asked for from each of the 8 camps in Connecticut and I:assachusetts, and 200 men from the camp in Vermont. It is expected that positions will be approved for three supervisors, one for each of the three States# These supervisors will direct and manage, under supervision, the gipsy moth work from all camps in the State where iaen have been placed for this work. The immediate supervision in each camp where 100 men have been placed for gipsy moth work will be done by 4 foremen, consisting of a top-foreman who will be assisted by 3 under-foremen. The first work of the foremen in the camps is to train a z.iall crew of enrolled men from whom small-crew foremen will be chosen. The gipsy moth work in the Vermont camp where 200 men were asked for will be supervised by a top-foreman assisted by 6 under-foremen, and approximately 18 men fron the labor group will be trained to act as smallcrew foremen. The foremen who are being recommended for positions in this work are being picked with considerable care. These men must have had at least three years of experience in actual field gipsy moth control work in order to qualify.

The top-foremen are already in the four camps in Connecticut training men.

About 55 men have been turned over for this instruction, In .Massachusetts and Vermont no foremen have been placed in the campsas yet, as the State foresters of these States ,expressed a desire to use all of the labor in the camps on other projects at first., It is believed that by the end of July or very earlyin August .our entire.quota of foremen will be in and that actual scouting wdrk can be started

The plans call tor scouting of all the woodland in the area between the Connecticut 'iver and the. barrier zone in Connecticut and Massachusetts and for similar work in a large area in the southern part of Vermonti As infestations are
-found, the egg clusters willbe treated with treosotej and thorough cleaning work such as .chopping and burning of undesirable tree growth will be done& It is hoped that this work,can be followed next June with an intensive spraying program

I IN 'I'HL: JUDGMENT OF THE -TI-JSPECTOR . . .. This phrase 1s of common occurrence in quarantines and regulations, where. •it appears in various forms such .as, "as the inspector may require", "in the opinion of the inspector", etc. The use of such 6:D. expression arises from .the practical impossibility of fo reseeing in advance and establishingbeforehand correct procedure for every situation that is likely to occur. In certain fields of quarantine work . . . cases a.re constantly being. met which show such endless variatiQns and widely diver-sified conditions that it seems more sensible and more fair to the public to handle them with due 'regard to the accompanying .circumstances rather than attempt to fix in advance a c omplete set of rules which for many individual cases are bound to be either inadequate, or useless, or unnecessarily harsh., With a measure of discre-tionary power in~orporated into the ~egulatio~s a certain flexibility is provided for and the actual procedure adopted. comes more nearly in accord with the biologi-cal l'lecessi ties in .each case a . . The term II judgment of the inspector" is not to be c onstrued too 11 terally, hoi'Tever, as denoting merely the ruling of the individual employee. It is rather to be understood as a legal term, embodying the opinion and decision of the whole Department as an ndministrati~e agency. The inspector from this viewpoint is not to be considered as an individua~, but as the agent through whom the purposes of the Depnrtment are carried out, by virtue of instructions from the Bureau head, the administrative re~1e sentative of the Departirent. The _inspector• s action nru.st, therefore, be always in line with the policy of the Departr,1ent and .in accordance with instructions, insofar as policy has been established and instructions have been issued. Where some 9articular situation falls outside the scope of such fixed policy or instructions do not cover it, the individual judgi~eht of the inspector comes into play , thou.gh it must still be recognized that such judgment can in no case be exercised outside the regulations or the act on ,;rhich these regulations are based.

TRANSIT INSPECTION Empty refrigerator cars arriving at Chicago fron1 the Japanese beetle infested areas are b eing checked by transit inspectors to insure their being swept and cleaned of all rubbish which may carry the beetle, as provided by quarantine r egulations • . Shipments of soft-shelled crabs packed. in cedar boughs and parts of. other plants tha t should have been certified under Japanese beetle quara11tine regulations were recently noted at Philadelphia, coming from ~he Eastern Shor~ of Mary land. Grape leaves, packed in and saturated.with salt, were found by a . transit inspector at New York to have been consigned from the Atlantic to the Pacific Coast. These shipments were reported to the field office in order that the shippers migh t be locate d and arrangeF~nts m.Bde for certification of future similar shipm ents • .

-6WHITE-PINE BLISTER RUST 11h~ inspection of pine-~owing ~urseries in 11aryland and Virginia is now under way, and it is found that Ribes on these areas are much scarcer, and the problem of P.ibes eradication much simpler, than is the case in 1re w England. Bureau inspectors working in cooperation with .State authorities of Iowa. and Minnesota report, on the other hand, difficulty in accomplishing complete eradication around the pine nurseries in those States. Crews had to cover the territory around some nurseries several times before tbe .Yror.lt was completed to the extent required. Several-nurseries are plannin~ on changing locations in order to ~rovide areas where Ribes are easier tq eradicate. Favorable action on 6 a pplications for pine-shipping !;}erri1i ts has thus far _ been to.ken for the. fiscc1.l year 1934. Two of th9 nurseries are located in Virginia, 1 in New York, and 3 in New England. Four of the permittees were found.to e growing pines in Ribes-free zones, and were'therefore authorized to ship, while the premises of 2 others were tentatively appro~ed, subject to reapplication and inspection :prior to shipping. About 30 other applications are under consideration. The joint certification tag de~cribed on page 8 of the June News Letter will be employed in the case of nurseries located in areas regulated on account of the gipsy moth and Japanese beetle. NARCISSUS BULB PESTS The Bltreau is compelled, under the limitation of funds available for the present fiscal year, to withdraw all assistance heretofore given the States in the inspection for narcissus bulb pests. While there has never been specific Federal appropriation for the inspection of narcissus, employees on other projects have been able, in the-past, to give son e incidental aid to State inspectops in the diagnosis of pests and in maintaining high standards of treatment and practice. Notice hasrecently been sent by the Chief of the Bureau to officers of t~ese var ious States that it will not be possible to rende r any such assistance this year • • Supplementary adrninistrative instructions relating to narcissus treatment and pest suppression have been issued by tm Bureau as circular BPW-353. The new circular authorizes the use of the vapor-heat treatment for bulb flies in lieu of the hot-water treatment, if desired. It also changes the pre soaking requirement by reducing the length of t :ime dry bulbs are required to relY'..a.in in cold water, from '12 hours to 2 hours. A number of interpretations and slight modifications of the administrative instructions concerning narcissus inspection issued last year are included. ELA.CK STEM RUST The che~king ol nurseries under the black stera rust quarantine was begun about the middle of July by L. H . Ames, of the BUrea u of Plant Industry, who is working in cooperation with this Bureau. Nurseryruen enga3ed in .the shipping. of barberry and l , iahonin plants to or betvrnen the 13 barberry eradication States of the Middle West apply in the spring for inspection of their premises. If they

No such permits are, howeve required for the Japanese barberry, which is immune to the disease. PHONY PEACH DISEASE Under the new plan ofcooperating with the States in preventing the spread of the phony peach disease, branch headquarters have b~en established at Texarkana Tex., and . a Bureau inspector will work • out from this point, going with the nursery inspectors over the environs of peach-growing nurseries. He will work primarily in Arkansas, Louisiana, and Te:x:as. Atlanta is continued as headquarters for two other inspectors now working similarlr with the State inspectors of Georgia, Alabama, and Tennessee. They expect toreach North Carolina, South Carolina, ~lississippi, and Illinois a little later. State restrictions with reference to the phony peach disease and the peach borer have been passed recently by Mi~sissippi, Georgia, Arkansas, and Delaware, following the revocation of Federal quarantine no. 67. DATE SCALE ERADICATION During the month of June a small planting of palms on the property of E. E, Forrester, in the Imperial Valley, was i:p.spected for the first time since Februar, 1932, ~though located in the infested area and having shown scale in 1930. The: were 13 palms in this planting, the tallest about 15 feet to the bud. Water frol the main irrigation canal was allowed to flood this and adjoining properties at about a 7-foot level for several months. About 6 feet of silt was deposited,. leveling the land. Incidentally the time necessary for inspection of the palms was greatly reduced. Water reached the buds of 9 of the palms, all of which die< The 4 whose buds were above the water level survived and seen1 to be doing very we: This chan eing of the land level has been noticed on several previous occasions w hen digging out worthless palr!J.s along ditch banks. Sometimes it has been necessary to remove about 5 feet o:f soil be fore reaching the base of the trunk. lifo new infested properties were found a.uring the• past fiscal year. The last new infested property in the Imperial Valley was found in June 1932, in the Coachella Valley in ~!Tay 1930, and in Arizona in April 1930. The number of infested palms found has decreased. from year to year as follows: Fiscal year 19291 1,590; fiscal year 1930, 621; fiscal year 1931, 232; fiscal year 1932, 59; fiscal year 1933, s.

Tabulation o f data pertaining to treated nursery plots and heeling-in area ane.lyzed early in the s-.9ring by the Toxological Division shows that 771,656 square

PAGE 12

-11-feet of heeling-in area and 4,954,497 square feet of nursery plots containing gro ing plants, or a total area of 131.5 acres, was sampled and analyzed for lead arse na.te content. Of the areas analyzed, 358,023 square feet of heeling-in area and 3,000,248 square feet of nursery area required retreatment with varying amounts o arsenate of lead. The surface area requiring retreatroont is approximately 59 pe cent of the total analyzed. During !v!ay and June, 51.l acres of nursery plots an 7.2 acres of heeling-in area were retreated with rufficient lead arsenate to brin the concentration up to the required 1,500 pounds per acre. District supervisors conferred at the Harrisburg headquarter~ for the ~1rst time on June 2. Considerable time was given to a discussion of several new phase of enforceimnt of the summer quar&"1.tine on fruits and vegetables. Personnel mat• ters in connection with nursery and greenhouse scouting and farm products inspec• tion were talked over, and the necessity emphasized. for employment of only a minimum te:Ql.J;)orary force and ell.mination of all motor vehicles possible. Visitors to the storage ~arehouse of the project at the General Depot ot the u. s. Army at New Cwnberland, Pa., usually are driven the length of the six bays in an automobile or else ride bicycles during the inspection trip. The ware house is 840 feet, or 0.16 mile long, with a round trip, through one lane of fire . doors and back the other lane~ of approximately one third of a mile. Scouting of classified nursery and greenhouse establishments and adjacent p~mises for a radius of 1,000 feet began in Virginia and Maryland on June 12 and in Delaware on June 15. Similar activities in New Jersey and Pennsylvania will get under way on July 1, and on later dates in the more northern States in the regulated zone. Conununity spraying with coated arsenate of lead in cooperation with the Maryland State Horticultural Department was performed in Laurel, Elkton, and Colgate duringJuner The spray was applied by means of two 600-gallon capacity Fitzhenry-Guptill high-pressure sprayers. Truck drivers paid by the Bureau oper• ated the sprayer trucks. Hoseman, nozzlemen, and erew foremen were ~aid from Maryland :funds. Agent .w. F. \Valshj from the Harrisburg headquarters, supervised the work. Dr. G. s, Langford, of the Maryland Department, made frequent visits tc 1 the scenes of operations. Characteristics of the three localit.ies sprayed variec 0 in each instance. In Laurel the si)raying was in a distinctly t>ban community, I with many shade and ornamental trees. Premises sprayed were in general well kei:r and had plantings of flowers and ornamental shrubs. An ordinary orchard nozzle 0 was effective in reaching mo.st of the foliage covered. A short Worthley nozzle t was used for some larger trees. Care was necessary to keep the spray drift from houses.,. The lead oleate-lead arsenate spray was applied at the rate of 9 pounds of the paste to 100 gallons of water1 making 54 pounds of the insecticide to one tankful of water. . Water was obtained at the city pumping station in Laurel. In each of the three cormnunities sprayed, warning placards were tacked in con3 s:picuous place. s in the localities to be sprayed before the crews began their work, t Scarcely any difficulty was experienced with the persons occupying the sprayed P premises. The work was largely welcomed as an attempt to control an annoying pef Three laborers were used in each crew to drag hose.

The heavies t infestation or the three is in a woodland section north of E lkton. In addition to low V!ild (9-'0 Wth, a number ,of tall trees were sprayed in this locality. Lont; and short Wort ,hley nozzles iiere. used exclu.sbrely in this woodla,nd section. The infestation bord~rs several small strea~s, from ~ hich water was pumped directly into the tanks. '1110 }1ridges were not strong enough to carr:r the weight .. of the loaded trucks. It ,vas therefore necessary to adjust the work of the sprayers so that they did not _ 1eed to pass over the 1,1eakened structures in gping to and from .operations. Foliage conditions i n Col gate offer s omewhat of a combination of urban plantings _and woodle.nd area. The infestation extends for a short distance back from ::as.tern .Avenue and North Point ~oad in surbur.ban Bultimore. Th7ellings are o f the small, frame bungalow t ype, witlJ. small yards and fe11 lamis or extensive flower or shrubbery plantings. Be~rond the dwellings are nt1.,.71erous small trees and considerable thick first growth. In opraying all foliag e encounterec, it 11as necessary to pull hose through thic ~ets, ar.'.Dng which considerable :poison ivy grows. The men were also ~uathered by chiggers. From Col gate it v7as necessary to drive the truck s several r.liles to a Baltimore Cit:r fire station to obtain water from a hydrant operated b~r a paid fireman. In Laurel and Elkton all l aborers were hired t .hrough the local r,elfare committee or a IP.unicipal official. Nozzle:men hired in Laurel stayed YTi th tm outfits in Elkton end Colgate. At the conclusion of the spraying_ in each community, small cages of perforated metal each containing a smll jar of gerand.ol-eugen.ol mixture, equippe d 1.1ith -rvicl~ for volatilizing the liquid, were hung at the rate o f four o r five per property in grape arbors, rose bushes, _and other preferred food pla.~ts. In Erie, Pa., last year the sDray mixtuT e ap-. plied contained c;eraniol and syroline fo r the purpose of attracting the beetles to the apr2yed foliage. Frequont a~plications of the attractant were necessary throughout the season.

A nt.unber of other s performed some Japanese beetle quarantine ins_pecti_on work in connection. w ith their corn borer inspection visits. This combined wo'rk was compensated for by an equal amount of corn borer inspection performed by the reiular Japanese beetle inspectio corps.; The e;reatest demands for ]federal corn b0rer certification service were in the New Jersey, Lon g Island, and Boston areas. To and including the month of Jun1 approxiraately 3,500 shipments were certified for movement to the States accepting only Federal certification. In view of' the general business conditions in the v nursery trade, this quantity of stock moving to eight rather distant States con-i stitutes quite an item in keeping open the regule.r channels of trade, ~d o .ffers I somewhat of a marginal outlet fox stock which without Federal inspection would be prohibited movement. :MEXICAN FRUIT FLY The greater 1')art of the month was occupied in completing the application of poison spray which was started May 22. A rainy spell of four days set the work . back after it had gotten off to an excellent start. With this one except ion the weather remained ideal, and since the growers as a whole had no pressing routine jobs confronting them, the spraying moved alone; rapidly. A number of outlying groves of young trees v1hich experience has shown are not likely to harbo~ an infestation were omitted from this a pplication. However, 3,875,075 trees or app roxiri1 ately 5 5,000 acres of bearing groves were sprayed. A total of 21,240 gal-lons of molasses and 1,059 gallons of nicotine were used. Five hundred knapsack sprayers were used b y ap }:iroxima tely 7,500 individuals in applying the Sl)ray, ,In &d n di tion to the knapsack sprayers, a few of the growers preferrea. to use their power h sprayers. n p, The set-up f o r the distribution of the m aterial was much the same as in p: previous applications. Where only small quantities of molasses and nicotine were i1 req_uired, delivery was made at the ,Tove by the inspectors. Owners of large b : planting s called at the distribution depot for the material. Each inspector was il assigned certain roads or areas and had from 15 to 20 lmapsack sprayers. It was E his du.t :r to contact the growers of his area, make arranger aen ts for the spraying o~ w l t h e groves, deliver the material and the sprayer, su.1Jervise the a 1Jplication of the ti s pray and pick u p the sprayer when the spraying was completed ai1d deliver it to 'f. tl::.e next grower w ho v m s ready to start. It was found that the most effective wor , 51 could be done from about 6 to 9 p.m. when most of the growers could be found at-m ih~ir homes~ m tl In addition t o the supe;rvisiilg, done by the distric~ inspectors three inspec tc tors w e:re ass i gned f1...dl time to this ciu.ty. Considering the large number of indi-viduals a:pplying t h e poison it was fonna. that a.i"1 exceptionally good application had been made. Abandoned and absentee-owned groves constituted a difficult probwt lem. The spraying of these properties was accomplished by various methods.

This work was accordingly started du1"'i11g the latter T)art of th,e . mo.nth, ) , ft J , PINK BOLLi.70Rl'il • ' . . The main activity on the pink-bollworm project during the month was -in con nection with trap plats of cotton instituted .as O'ne of the measures to reduce the heavy infestation of pink bollw o rr..:1 in the Big Bend area of Texas. Blooms have. now appeared on all of the 67 plats and infestation has been found• -in 52 of these plats. . In order to arrive at the results being accomplished bjth'e 'trap-planting program, plans wsre made to examine blooms from local field cotton to r comparative infestation, this to be earl.lied out by inspection of an. equeJ. n'Ll.l1lber 'of rosetted blooms from the plats and the nearest cotton fields. The field cotton was bloom~ ing sufficiently by the last vreek in June to begin these comp~ative e ,xaminations. Blooms collected from 3? fields disclosed. that 14 of the fields were intested; w hile blooms from 37 adjacent plats s h owe d 24 of the plats to be infested. From the 14 infested fields 2? pink bolluorms rrere taken, and t he 14 adjacent plats yielded 46 pink bollworms. The following vreek infestation counts were made in 50 nearby fields, 2G of which were found to be infested, yielding 80 pink bollworms, while 346 pink bollw orms TTere taken from the blooms of adjacent plats. Vlhile it is early to draw conclusions es to the ultimate benefit of the traps, the above readings indicate that the advanced trap plantings are noreattractive to tbe moths than field cotton. It may be o f s01,ie interest to note that at Castolon, in Brewster County, where only a small isolated cotton acreage is grown and it was impracticable to carry out the special program, 21 rosetted bloons ~7ere gathered from one half acre of cotton, from which 19 pink boll•m r !'ls wm-re removed. It uill be recalled that Brewster County was a noncotton zone for the season of 1928.

-15In the Salt River yal+ey of Arizona a small amount of field inspection was m made in the 1933 crop. Some 800 squares and 750 bolls were collected from the n Ring field at Laveen and examined, with negative results, It will be remembered t that' this wa_ s on~ of tpe la:st fields to be found infested in: tha~ district, no in T festation having been found in the area since the 1931 crop. In Florida the clean-up program of wild cotton on Key Largo was completed a rn d at the close of June. There was considerably less wild cotton on the extreme upw per end than on the remainder of Key Largo. There was a very heavy distribution a on Sound Point, which is actually a separate island but at the time of ~he origina 1 survey was thought to be a part of Key Largo. During the month 50 acres were cleaned, from which 20,735mature and 5;925 seedling plants were removed, and of this aL1ount 15,365 mature and 4,355 seedling plants covered 40 acres on Sound Point. In addition to the above, 14? domestic doo~rard cotton plants were remove from 21 different locations in Dade County, and a. total of 240 bolls examined froni i a u these plants gave negative results. a Laboratory inspection has been continued throughout the month. At the d Alpine and El Paso offices seed samples were examined, these samples originating n in the States of Arkansas, Mississippi, Missouri, and Tennessee. At the San An-8 tonic laboratory and the various field stations green bolls and bollies were ex-6 amined. No specimens of the pink: boll worm were found in any of the material ini: spected. In addition to boll examination at Miami, a daily collection and ina spection of blooms from the plat cotton at Chapman field was continued, with nega • v, tive results, throughout the month. 6' The working model of the small gin-trash n:a chine, mentioned in last month'~ 11 News Letter, has been completed and tested out satisfactorily. Some 8 or 10 of s: these .will be available for use at the opening of the gin-trash-inspection season t: in areas of limited cotton production. These little machines combine the essen-m tial principles of the big machine; they have a drum 2 feet in length and approx: SI mately 2 feet in diameter. The machine is so adjusted that when turned too fast the material adheres to the circumference of the drum and stops feeding; otherwisE ru C( the worms present in the trash would be picked up and discharged through the suc-tion fan and lost. As stated in the last News Letter, the machine is light enough to be handled by one man, and it will undoubtedly prove a valuable additio1 :n to our inspection equipment. It will enable us to perform efficient and economi• i cal inspection in certain areas not heretofore practicable. r PREVENTING SPREAD OF MOTHS f , t 1 UI Spraying was carried on in the Connecticut and Massachusett's section of thE bi barrier zone during the month, a total of 15 sprayer machines being in use! Ex-h: oept for occasional days when there were high winds and some local showers, the k: weather throughout the month, vvas hot and dry, malcing ideal c9ndi tions for sprayinfs operations. The dry weather, howev~r, brought about a shortage of water in

PAGE 17

many ~f:il. l str~ams and brooks which we.re be in,g used to furnish water to mix arsenate of_. lead spray solution, and because of this it was often necessary to move the s9rayer trucks to new locations or haul water from a considerable distance. The two tractors transferred to this project from the Corn .Borer-Japanese Beetle activity_ earl_ier in the season proved valuabl_ e in hauling sprayers over rough mountain roads to points more accessible to areas where spraying was to be donduoted. During periods when the foliage was too wet to hold the spray the men were employ~d in laying new hose lines and doing rough cleaning work in'the immediat~ vicinity of infestations where sprayihg was being done. By the time spray ing was completed at the end of the month, more than 1,900 acres had been sprayed, a totai of 38 tons of arsenate of lead and ~,800 gallons of fish ?il having been used. In the Pennsylvania area we_ather conditions were also excellent for spraying, yery little time being lost on account of rain or wet foliage. A total of '26 sprayers were in operation during the month. Although considerable difficulty was at first experienced in training local men to properly hold the spray nozzle, by diligent effort the Federal employees supervising this v,ork taught a sufficient number of them to do this difficult' task in a satisfactory manner. This type of spra'y'ing was ne,r to them and they therefore could not at first understand why the solid stream should not be turned dire~tly onto the foliage rather than to hold it in such a manner as to allow the mist spray to drift onto the .foliage. It was also difficult to get the_se. men to move the nozzle as rapidly as they should to :pre vent waste and secure the most satisfactory results. They apparently did not ,realize the volume of rJaterial passing through the tips such as are used in s _olia_-stream sprayihg. Mo st of the difficulties were straightened -out during the first week or 10 days and the nozzle.men, considering their limited experience in solid:-stream spraying, performed very good work. To July l, 21800 acres of woodland, including the cut-over area, and 5,?00 isolated trees had ooen sprayed. In addition to this work, . trees, shrubs, vines, etc., were sprayed on 4,800 properties in residential sections within the heavily infested area. ,Hore than 48 tons of arsenate of lead and 1,900 gallons of fish oil were used up to the first of July, Spraying will be ~ontinued in the Pennsylvania area for ~bout one week in July. Although it wz.s feared that cattle ancl goats might be poisoneo. because of , ~eg;tig_enc~ on t ):1e part of the mmers in permittin~ them to graze in the sprayed _e.rea after being warned several times of the danger in allowing them to -~o. so> no reporf he,s as yet been received indicating tha t any of these ~imals ~ a ve been affected. There was a total of 38 properties for which owners or tenant~ refused to sign sprayilg permits. After being served with a State notice, these properties were sprayed under the direction of a full time employee of the Pennsylvania Depa!tment or Agriculture. _When the foliage was too wet fo r s praying , the ne n pat~olled the burlap bands attached to trees in t h e infested area a nd killed gipsy moth larvae found hidden beneath them. To and i n c luding June 30, a total of 45,561 l aryae had been kilied under these bands. Very littl. e serious mechanical trouble was encountered with the spraying eouipment anywhere in the field this season, a m such as did arise was quickly

•l?remedied by mechanics with service_ trucks detailed especially fo~ this work. Ser vice trucks made daily visits to every spraying n:e.chine and corrected.~ any troubles reported by the operators. The spraying program in Ne\-1 Jersey was completed by the middle of June, an area o . f 60 acres of woodland around the infestation in Mendham Township having been sprayed. Upon completion of this work the sprayer loaned by this project to the State was returned to Wilkes-Barre. A check-up was made of the tanglefoot bands after spraying was finished, and no living -gipsy moth larvae were found. Arrangements have been completed for placing assembling cages in Ne"H Jersey. This office has furnished the State of New Jersey with 850 assembling c-ages together with attrahent and other material necessary for the work. The cages will be put up and patrolled by employees of the State of New Jersey. It is plan.~ed.to place cages in Mendham and Randolph and a group of townships surrounding them to check up on the scouting ana. treatment work. carried on during the fiscal year 1933. The infested area will al.so be rescouted during the fiscal year 1934. Preparations for the assembling cage work which is to be carried on in .July were well under way by the end of June. The substation at Middleboro, Mass., on Cape Cod, where bait materials are obtained, and ,.,here collections of various stages of the gipsy, brown-tail, and satin moths are mounted for specimens, was opened and preliminary work started. Considerable scouting has been don~ for sizable gipsy moth infestations at which 1are;e collections of female pupae may be made . It is :planned during July to put up assembling cages in 53 townshi,ps in and surrounding the known infested axea in Pennsylvania. In the barrier ione in Ne.w England and in the are. a directly to the east of the zone, it is planned to place assembling cages in 8? towns. As mentioned above, assembling.cages and material have already been fu:rnished to the State of New Jersey. In accordance vnth a request from the Canadian Departnent of Agriculture, this office has furnished them with 25 asserablins cages. These are to be put out in Canada along the intern2.tional border, as was done last y'ear. , ' At this season of the year when both gipsy and brown-tail moths _are in the i~rval stage, inspectors exaraining shipments prior to certification may find larvae of o n e or the other on almost an~r type of materials, sometimes 1i1here least expected; In illustration of t his, a report has been received from the district inspector of ' t h e Concord., N . H,, district tha t he found a brown-tail caterpillar on a consign .. r.1 ent of monumental granite being _shipped from_Ooncord to a destination in Iowa. Although there is a grow i ng tendency toward moving the various .. types of l quarant ineo. products by truck instead of b y freight, such m ovement is commonly con fined to distances within a corn,paratively few hundred miles of point ::>f origin. P.apid transportation between exact point o f origin Md exact destination, avoiding the necessity o f movement to and from railroad shipping points, is a factor that h a s decided the choice of trucks over freieht. For long distance moving, however, usually such materials are s h i2Jpe d throue;h railroad channels. Occasionally, a s hipment is moved for a lonG distance b y truck because of unusual c;i.rcumstances s ur-]'.'.oundinG the shipment in question. :Recently, a large ana. valuable ornamental evergreen was shipped b y truck fl'on Connecticut to a point in Ohio, a distance of

PAGE 19

-18-over 800 miles. The tree 'With ball of earth weighed about two tons and as it was particularly valuable it was decided to have it reach destination with as little delay as possible. It could be transported by truck :tm.1ch more rapidly than by freight, ani also there vras no possibility that it would be injured by heating, a condition to ~hich it miBht have been exposed if shipped in a freight car. A summary of the survey of brown-tail moth distribution which was carried on by enployees ~f this project during the .;!inter and spring, together with reports from State officials, indicates there has been a marked increase in the infestation in New ~ngland as compared with last year. This is based on the number of browntail moth webs cut and reported during the winter of 1932-33. Over 1112?,000 hi bernating webs were cut and destroyed in Nerr Hampshire and Massachusetts. No re cord is available of the uebs that were cut in the State of lffi.ine . There was a material spread of this insect beyond the quarantine line in L'faine and ITei7 Hampshire, even reaching into five towns alone the Connecticut River in the State of Vernont, In Maine, 20 towns beyond the quarantine line were found infested, and in Hew Hampshire 18 tomis beyond the quarantine line were found infested. In Massachusetts, Rhode Island, and Connecticut, no infestations were found in towns outside of the quaruntine line. For the :past fevr months considerable tim e has been given at this office to plans in coP-~ection with the gipsy moth vrork which might be done as a part of the Emergency Conservation Reforestation program. On April 1, s. S. Crossri1an, of this office, was placed.ihn charge of this Bureau's activities with relation to the gipsy moth part of the e11Brgency program. The reforestation TTOrk was organized so quicldy and in such an extensive way that it has been difficult to plan the work end procedure, and some readjustment has been necessary. The object of the Etlergency Conservation Gipsy Foth work east of the barrier zone is to find ancl destroy the g i p s y moth infestations thqt are present betTTeen the barrier zone and the Connecticut River, This will protect the barrier zone and aid materially in :reventing the westt1ard s pread of this insect. It is hoped to use approxin:ately 1,000 men from 9 emergency conservation work camps situated between the barrier zone and the Connecticut River. Four camps are located in Connecticut, four in Massachusetts, and one in Vermont. The use of 100 men has been asked for from each of the 8 camps in Connecticut and Hassachusetts, and 200 men from the camp in Vermont. It is expected that positions will be approved for three supervisors, one for each of the three States, These supervisors will direct and mana13e, under wpervision, the gipsy moth work from all camps in the State TThere r:ien have been placed for this work. The immediate supervision in each camp where 100 men have been placed for gipsy moth work will be done by 4 foremen, consisting of a top-foreman who will be assisted b y 3 w1der-foremen. The first '\'Tork of the foremen in the camps is to train a sr.1all crew of enrolled men from whom small-crew foremen will be chosen. The gipsy moth work in the Vennont camp where 200 men were asked for will be supervised b y a top-foreman assisted by 6 under-fore men, and approximately 18 men fro~ the labor group will be trained to act as smallcrew foremen. The foremen who are being recommended for positions in this work are being picl~ed 1.vith considerable care. These men must have had at least three years of experience in actual rield gipsy moth control work in order to qualify. The top-foremen are already in the four crunps in Connecticut training men.
