Everglades Station Mimeo Report EES65-5 September, 1964

PRIMARY EVALUATION OF PREERG POSTEMERGENCE APPLIED
HERBICIDES IN VEGETABLE SPRING, 1964 1/
J. / senigo 2/


Summary: The standard herbi&f, preemergence-applied CDEC at
3 Ib/A, continued to maintain superior annual grass
and sedge control with good general ero. tolerance,' The test crops were
slightly more tolerant of both pre-planting and preemergence applied
Trefmid than CDEC. Trefmid provided good grass control and very poor sedge
control. The other preemergence herbicides tested demonstrated varying de-
grees of crop effects and were unsatisfactory herbicides. Except for specific
exceptions, crop tolerance to the following effective grass and sedge herbi-
cides was poor: ametryne, CDAA + CDEC,. C-2059, CP-31393, CP-45592 and GS-
10293.

Good to excellent postemergence control of annual grasses and sedges
was provided by ametryne, D-2492, G-12344, GS-14260, GS-17269 and paraquat.
Bromacil and G-36393 controlled annual grass weeds but not sedges. Crop
tolerance to these effective postemergence herbicides was poor.

Generally, adjuvants did not differ markedly in influence upon post-
emergence-applied herbicide toxicity to crops or weeds.

Experiment: 1088 12 64

Location: EES, Field 2 E 5, 6

Soil type: Okeelanta peaty muck

Cultural operations: Field preparation; February, March 1964.
Soil insecticide; 10 March 1964 (Diazinon, 4 Ib/A)
disked-in
Fertilization and fitting; 12 March 1964 (800 lb/A,
0-12-16 with micronutrients)
Final fitting; 6 April 1964
Crops planted; 7 April 1964
Routine fungicide insecticide applications were made
weekly or more frequently when required.

Design: Non-replicated single treatment plots. Vegetable (21
best varieties) and field (6 test varieties) crops were
planted in north-south rows. Herbicide-treated strips
(6 ft. wide x 60 ft. long) traversed the crop rows in an
east-west direction. Handweeded, unweeded and CDEC (3 lb/A) standard herbi-
cide controls were interspersed among the treatments at intervals.

I/ This tabulation of the comparative performance of commercial and experi-
mental herbicides on the organic soil of the Everglades in the spring of
1963 was prepared for herbicide researchers and the industry. The data
presented neither constitute nor imply recommendation of any herbicide
for any usage.

Description of test crops: Not all test crops attained sufficient stand or
growth for adequate evaluation. Table 1 lists the
crops and their growth stages when postemergence treatments were applied. The
data tables list crops which were evaluated.

Description of weed population: No weed seedlings had emerged at this time of
herbicide application but weed seed had commenced
germination. Weeds in the postemergence plots at
time of application were typical of the experimental
area and the unweeded controls. Weed infestants and their developmental stages
at postemergence application are listed below; the major infestants are marked
with an asterisk (*).

*Alexandergrass (Brachiaria sp.): to 4 true leaves,
tillering, to 6 in. tall.
*Goosegrass (Eleusine indica): to 6 true leaves, tillering,
to 9in. tall.

Purple nutsedge (Cyperus rotundus): to 4 leaves, 6 to 8
in. tall.

*Annual sedges (Cyperus & Kyllinga sp.): to 4 leaves,
2 to 4 in. tall.

Broadleaf occurrence (especially spiny amaranth) was light
and sporadic; broadleaves did not exceed
grass weeds in height.

Description of herbicide treatments: Herbicides, formulations and suppliers
are listed in Table 2. Rates of application are given as
lb/A active ingredient or acid equivalent, whichever is
appropriate.

The single preplanting treatment ("Trefmid") was applied to
fitted soil, incorporated with a rotary tiller, rolled and planted.

Preemergence treatments were applied broadcast to the soil
surface after seeding in rolled soil. Water was the carrier. Carrier volume
was 50 gpa and treatments were applied with a Hypro roller pump on an experi-
mental herbicide tractor.

Postemergence herbicidal treatments were applied as broadcast
topical sprays over crops and weeds with the same equipment at 50 gpa carrier
volume.

Surfactant rates are given as percentage of commercial formu-
lation by volume per volume of carrier, i.e. o v/v.

Herbicide application data:
Preplanting incorporated: 6 April 1964, (300 PM, wind nil)
Preemergence: 8 April 1964, 0650-1000 AM, wind SSE 0-4 mph,
fog to full sun, spray water pH = 7.5, hardness = 390 ppm.
9 April 1964, 0615-0630 AM, wind S 0-2 mph,
fog, spray water pH = 7.5, hardness = 390 ppm.
Postemergence: 29 April 1964, 0540-1005 AM, wind S 0-5 mph,
fog to overcast with occasional light sun, appreciable
dew remained on plants until 0930 AM, spray water pH
7.5, hardness u 350 gr.









Surface soil moisture: (NB field capacity ca. 160%)
After preemergence application on 8 April:
shallow, O 3/8 in. depth = 98%
deep 3/8 1 in. depth = 133%

Rainfall data: Total accumulated rainfall for week after application indi-
cated:

application emergence* emergence

*Does not include 1/3 in. overhead irri-
gation 5 days after application.

Temperature data: Average temperature values are given for indicated period
after preemergence application;

1 week 85 61 73
2 83 58 70
3 89 65 77
4* 87 69 77

*These values also apply to 1st week after
postemergence application.

Method of evaluation: Untreated and CDEC control strips served as crop and
weed standards against which the experimental treatments were
compared on a 1 9 rating scale. The rating values were
converted to percentages of the best treatment for this report.
Visual evaluations were made at 31 weeks after application of
preemergence herbicides and at 1 week after postemergence
herbicide application.

Experimental results: The preemergence standard herbicide, CDEC at 3 lb/A,
continued to provide superior annual grass and sedge control
with a high level of general crop tolerance. Trefmid (applied pre-planting
or preemergence) controlled annual grass weeds about as well as CDEC; sedge
control, however, was very poor and annual sedges almost obscured the shorter
crops at 5 weeks after application. General crop tolerance was excellent.
The 2 application methods differed little in crop tolerance or overall weed
control. The combination, CDAA + CDEC, maintained good to excellent control

of annual grass and sedge weeds but general crop tolerance was fair. General
crop tolerance was poor and annual grass and sedge control good with the
tested rates of C-2059. Good to excellent grass and sedge control and poor
overall crop tolerance characterized CP-31393; EC and WP formulations differed
little. Both EC and WP formulations of ametryne effected poor Alexandergrass
control, good goosegrass control and poor general crop tolerance. GS-10293
did not control Alexandergrass but provided good goosegrass and sedge control
with very poor crop tolerance. Crop tolerance to CP-45592 was very poor
while annual grass and sedge control was practically perfect. Certain crops
had a high degree of tolerance to most of the above preemergence herbicides.
Differential annual grass tolerance was noted for several chemicals. Crop
tolerance to many of the other herbicides tested was good but weed control
was not acceptable for organic soil crop production (please see Table 3 to 12).

General crop tolerance to most postemergence herbicides was poor regard-
less of effect on annual grass and sedge weeds. The following herbicides
were characterized by poor crop tolerance and good overall annual grass and
sedge control: ametryne (EC = IP), bromacil (poor sedge control), D-2492
(1 Ib. = 2 lb/A), G-12344, G-36393 (fair sedge control), GS-14260,GS-17269
(Ee more effective herbicide than WP), and paraquat (Tables 13 to 17).
General crop tolerance to postemergence-applied herbicide/surfactant
combinations was poor. Diuron + surfactant provided good annual grass and
sedge control but short residual persistence. Dalapon effectively suppres-
sed annual grass weeds but not sedges; 209-FG apparently was superior to
X-100 in enhancing dalapon's activity (Tables 18 to 22).

A number of surfactants differed little among themselves and had little
influence on the performance of atrazine as a postemergence herbicide. The
Atlox materials (50% active) were slightly inferior to other surfactants,
especially in effect on Alexandergrass. Alexandergrass control was invariably
inferior to goosegrass control with all combinations (Table 18 to 22).
