December 1, 1958

Gentlemen:

It has been nearly five months since the last Vegetarian was prepared. A lot
of things have happened since that time and we would like to tell you about them,
particularly the proceedings of meetings. We will not attempt to cover all the
papers presented, only the high lights of the meetings.

The Fifth Annual Vegetable Research Work Conference was held in Gainesville
on October 8th and 9th with approximately 75 people present. Among these were
vegetable growers, shippers, suppliers, University of Florida department heads
and research and Extension workers. In the two half day sessions, about 180 type
written pages of discussion took place all of which directly concerned vegetable
crops. Each Branch Station Head and Department Head gave a brief resume of
research work at his station or department then the floor was opened for dis-
cussion by all on needed work or comments and questions on current research.
The minutes of this meeting will be reproduced and distributed to those interested.

Following the Work Conference, a meeting of the County Agent Vegetable
Advisory Committee was held beginning at 2:00 P.M. on the 9th and in this
mrn-ting, Vegetable Extension work was discussed. Here are some of the points
brought out in this meeting:

Vegetable outlook information was considered to be valuable and the
report should be continued, however, it was suggested that the report
would be more valuable if prepared for release by August 1st each year.
A need for supplementary periodic reports was discussed as well as a
need for training County Agents in proper use of outlook information.

A need for more marketing information was discussed and Mr. Rosenber,;,r
discussed various sources of information presently available.

Vegetable Crops Extension agreed to give more information on new crops
and Mr. Rosenberger volunteered to assist agents develop markets for new
crops.

Extension publications were discussed and a tentative program for release
of information was agreed on. Production Guides should be revised and ke':;
available. Guides on additional crops were requested. The Vegetarian Ne-C-
Letter was felt to be valuable and should be used for reports of new research.
Vegegrams on at least six crops each year was requested.

A need for vegetable clinics on a periodic basis was agreed on.

Field days were considered to be worthwhile, however, they could be
supplemented with small groups of growers being organized to take one day
tours of stations throughout the year.

County Agent training meetings in vegetable crops was suggested as a
need and should be held in vegetable producing areas.

Other subject discussed were result demonstrations, soil testing
laison between Extension workers, research workers and commercial workers,
and resident instruction at the University of Florida in vegetable crops.

The annual meeting of the Florida State Horticultural Society was held on
October 29 31 in Clearwater, Florida.

Many good papers were presented and those of you that are not members should
make a special effort to secure a copy of the proceedings so that you may study
these research results.

I will list a few which I considered to be outstanding:

Dr. John N. Simons of the Everglades Experiment Station made an
outstanding illustrated talk on viruses and their complex host association
as well as how they are transmitted and controlled.

Most virus losses in vegetables are attributed to three aphid-borne
viruses:

1. Cucumber mosaic on pepper and celery which has as
a wild host, the wondering jew vine.

2. Vein-banding mosaic or Potato Y is serious on peppers
and tomatoes night shade is the wild host.

3. Watermelon mosaic on cucumbers, squash and watermelons.
The wild host is wild cucumbers.

Other viruses not transmitted by aphids, were:

Tobacco mosaic on tomatoes, harbored in tobacco products
and transmitted by tobacco users. This one is even
worse when the vein-banding mosaic is also present.
Another is Pseudo curly top on tomato which is of
minor importance.

Dr. Simons suggestions for control of aphid borne viruses is pre-plant
weed control and use of non-susceptible barrier crops. For the Pseudo-
curly top control, pre-plant weed control and the use of DDT plus parathion
around the field.

For a run down on most viruses in vegetables (Those of you that file
these Vegetarians) go back and read your Vegetarian of April 5, 1955.

Fungicides for Late Blight of celery was discussed by Dr. Darby of the
Central Florida Station. Late Blight caused by Septoria apii is not usually
the most troublesome disease of celery in Florida, however, this past year it
was serious in some areas. It was gratifying to find out that the same fungi-
cides recommended for early blight were best for late blight. These are:

1. Nabam plus Zn SO, 2 quarts and 3/4 Ibs.
2. Maneb ferbam (1:1 ratio) 2 lbs,
3. Diammonium ethylene bisdithio carbamate plus
calcium hypochlorite, 1 quart plus 1 lb.
4. Ferbam 2 lbs.
5. Dyrene 2 Ibs.

His lowest incidence of Late Blight was with dyrone 2 Ibs,, agrimycin
200 PPM, however, this was on a single row and no yields were kept. FDA
tolerances are not established for agrimycin on celery for field use.

Mr. Leon W. Miller of A. Duda and Sons, discussed the need for research
and development of new seed and varieties. He made some statements worth
passing on:

"We must produce quality to stay in the fresh vegetable business"

"Factors that enter the picture are, public acceptance and yields
as well as quality"

Dr. Marshall R. Godwin of the University of Florida, Gainesville, gave
some very interesting results of a study of Florida versus California Celcry
in the Chicago market.

This research indicates California celery is unable to command a very
large premium over Florida celery without suffering losses in sales. Florida
celery accounted for 57% of total sales when priced two cents under Calif.
Under varying prices, customers readily shifted from one to the other. There
was a slightly greater willingness to shift from Fla. celery to Calif. celery.

Dr. E. G. Kelsheimer gave the results of soil treatment for control of
nematode and mole crickets in shallot growing. O.K. What are shallots? To
you they are a multiplying onion used for green bunching. SMDC (trade names
Vapam and VPM) was outstanding for best yield used as a drench or it may be
applied in the row 5 to 6 inches deep at the rate of 1 pint per 100 ft. of
row.

Dr. V. F. Nettles of the Vegetable Crops Department, University of
Florida, Gainesville, presented the results of watermelon fertilizer trials.
1000 lbs./acre of 6-8-8 gave better yields of Charleston Grey than 500 Ibse

Dr. Emmett D. Harris of the Everglades Experiment Station, reported that
the methocel in a massive hentachlor or dieldrin seed treatment on sweet '*-rn
seed to control wireworms, reduced seedling emergence more than the inser--
icides.

Dr. William Lautz, U. S. Department of Agriculture at the Central Florida
Experiment Station, reported on nematode population after nematocidal treat-
ments with nemagon, telone, mylone and RPD. The nematode count was signifi-
cantly lower after 4 and 8 months where nemagon, telone or mylone were used.

Dr. C. H. Van Middelem, Agricultural Experiment Station, Gainesville,
reported that residues of DDT and Parathion on sweet corn kernels and cob.,
after as many as 15 consecutive daily apiications, were well below proposed
official tolerances, even when taken three days after last application.

The husks and fodder from sweet corn so treated should not be used for
livestock feed.

Mr. D. S. Harrison reported that toxaphene granules at the rate of 1 lb.
of actual toxephene per acre applied by the noble DDT applicator (Model
T-400) was superior to another applicator used and wettable powder sprays in
controlling fall army worms in whorls of sweet corn.

Mr. S. N. Edson, University of Florida, Gainesville, gave a very inter-
esting illustrated talk on a simple home hydroponics system using local
materials and commercially available 8-8-8 fertilizer as a nutrient.

Dr. E. N. McCubbin of the Potato Investigations Laboratory, discussed
potato variety tests. The results of his trials indicated Sebago and Red
Pontiac remain the best varieties except in soil infested with corky ring-
spot virus. Merrimack, Plymouth and Pungo are resistant to this virus.

Dr. John Malcilm at the Sub-Tropical Experiment Station reported that
water supply, significantly affected the availability of all major elements
to tomatoes on rocldale soil.

Dr. G. M. Volk, Experiment Station, Gainesville, reported that nutrition-
al leaf roll on tomatoes was not present where nitrate nitrogen was used but
did occur where urea or ammonium sulfate were used. Uptake of calcium was
least with these two forms of nitrogen.

Mr. E. F. Scarborough, Florida State Marketing Bureau, Jacksonville,
reported on the function of the Jacksonville produce distribution area in
the distribution of 15,750 carlots of produce over a radius of 125-150 miles
to serve 1.5 million people.

Dr. R. M. Baranowski of the Sub-Tropical Experiment Station, reported
that diazinon was most effective for control of serpentine leaf miner on
pole beans. The addition of maneb reduced the effectiveness of the diazinon.
DDT added to parathion reduced its effectiveness. DDT did not have this
effect on diazinon.

Mr. W. G. Genung, Everglades Experiment Station, reported on control of
insects or pods of table legumes. Thiodan looks good for control of cow rpa
curculio, stink bugs and other lepidopterous larvae. Thiodan plus toxaph...e
each at half usual strength gave best curculio control. Phosdrin and guti:on
look good for stink bug control. Thiodan, phosdrin and toxaphene are gon, on.r
salt marsh caterpillars and bean leaf skeletonizer. Parathion best for luina
pod borer.

Dr. H. Y. Ozaki at the Plantation Field Laboratory, reported that fall
planted peppers damaged by the cold last winter were kept and finally
produced over 650 bushels from the second crop on new growth.

NEW PUBLICATIONS

The Annual Agricultural Statistical Summary for 1957-58 season is now avail-
able from: Florida, State Marketing Bureau, 505 West Adams Street, P.O. Box 7.'7,
Jacksonville, Florida.

In closing we would like to say that in the near future we will attempt to
cover research in progress on vegetables at our Experiment Stations.

Sincerely yours,



Mason E. Marvel
Assistant Vegetable
Crop Specialist
