PRIMARY EVALUATION OF PRE-PLANTING AND OF PRE- AND POST-EMERGENCE
APPLIED HERBICIDES IN VEGETABLE AND FIELD CROPS, SPRING, 19621/

S1 2J. R. Orsenigo2/


Summa o herbicide applied sub-surface, pre-planting effectively
controlled annual weeds without injury to many crops.
There may be specific utility of some chemicals in certain of the test crops.
CDEC, the pre-emergence standard herbicide was not surpassed
in general weed control or crop tolerance. The most promising herbicides were:
Dacthal, diphenamid, FW-925, trifluralin and U-4513. N 2547, N 3291, R 1870 and
R 4461 were slightly less effective and less persistent than the foregoing
materials. EAP 2000, petroleum mulch, applied pre-emergence over herbicides
slightly improved the performance of some chemicals.
Emergence treatments demonstrated the most striking differ-
ences in performance between two DPA formulations. Similar but smaller differ-
ences in effect on crops and weeds were noted in pre-emergence and post-emergence
applications.
One post-emergence herbicide, SD 6623, was judged promising;
crop tolerance to broadcast topical sprays was superior to the other herbicides
evaluated although weed control was inferior to several chemicals. Test crops
were severely damaged by herbicides which most effectively controlled weeds.


Experiment: 1088 5 62
Location: EES, Fields 2 E 5,6
Soil type: Okeelanta peaty muck
Cultural operations: January and
Field preparation; February, 1962
Fertilization and fitting: 18 January 1962 (800 lb/A
0-12-16)
Re-fitting: March and April, 1962
Final fitting: 11 and 16 April 1962
Crops planted: 17 April 1962
Routine fungicide/insecticide applications were made weekly or
more frequently when required.

Design: Non-replicated single treatment plots. Vegetable (21 test
varieties) and field (9 test varieties) crops were planted in
north-south rows. Herbicide treated strips (6 ft wide by 60 ft long) traversed
the crop rows in an east-west direction. Handweeded, unweeded and CDEC (4 Ib/A)
standard herbicide controls were interspersed among the treatments at intervals.

Description of test crops: Not all crops attained sufficient stand or growth
to permit adequate evaluation. Crops planted are
listed in Table 1 and data for crops evaluated are in the following tables.

herbicides under the conditions of the Florida Everglades, Spring, 1962, was

Description of weed population: Germination of annual grass and broadleaf weed
seed had begun but no seedlings had emerged at
time of pre-planting and pre-emergence treatment. Weeds present in post-emer-
gence plots at time of application were typical of the unweeded controls and the
general area. These species and their stage of development at time of post-
emergence treatment were: Alexandergraoe, Brachiaria sp.; 6 to 12 in tall and
tillering.
*Crabgrass, Digitaria sp.; to 8 in tall and
tillering.
*Goosegrass, Eleusine indica; to 8 in tall and
tillering.
*Spiny amaranth, Amaranthus spinousus; to 15 in tall.
Purple Nutsedge, Cyperus rotundus; 6 to 10 in tall.
*Sedge, Cyperus odoratus; to 10 in tall.
*Watersedge, Kyllinga sp.; to 3 in tall.
Asterisks (*) indicate the weed infestant "of major
importance.
Weeds which occurred occasionally were Commelina sp., Acnida
cannabina, and a wild Poinsettia sp. The mixed sedge populations 6rginated mainly
from seed.

Description of herbicidal treatments: Herbicides, formulations and suppliers are
listed in Table 2. Rates of application
are given in the data tables in lb /A active ingredient or acid equivalent,
whichever is appropriate.
Sub-surface, pre-planting incorporation treat-
ments were made approximately 2 in deep with a blade 2 in thick by 4 ft wide
containing 7 #15003 TeeJet nozzles. The rate of water carrier application was 60
gpa. Plots were rolled after application.
Pre-emergence treatments were applied broadcast to the soil
surface after seeding in rolled soil. Water was used as the carrier for all
treatments except those in which an oil is indicated. Carrier volume, for oil or
water was 60 gpa and treatments were applied with an experimental herbicide
tractor.
Post-emergence treatments were applied with the equipment used
pre-emergence. Herbicide solutions were applied as broadcast topical sprays over
crops and weeds at 60 gpa carrier volume, water or oil.
EAP 2000 and EAP 2020 were applied at 600 gpa with the same
equipment.
Dates of herbicide application:
Pre-planting: 16 April 1962 (10:40 to 11:20 AM, wind nil)
Pre-emergence: 18 April 1962 (05:40 to 10:00 AM, wind nil)
Emergence: 23 April 1962 (01:30 01:45 PM, wind 3-6 mph)
Post-emergence: 17 May 1962 (05:45 to 09:30 AM, wind 0-8 mph)

Surface soil moisture at herbicide application: (N. B. Field capacity ca 160%)
After pre-emergence application: 0-3/8" = 66%
3/8 -1" = 112%

Method of evaluation: Handweeded and unneeded control strips served as crop and
weed standards. Treatments were compared also with the
standard herbicide, CDEC, 4 lb/A, pre-emergence. Visual evaluations of crop
stand and tolerance and weed control were recorded at one month after application
of sub-surface pre-planting; pre-emergence and emergence treatments and at two
weeks after post-emergence treatments. A rating scale of 1-9 was based upon non-
chemical controls. The values are reported herein as percentages of these
comparative standards. The letter "F' preceding tolerance values indicates
presence of foliar abnormalities in the specific crop signaled.

Experimental results: Seven chemicals (10 treatments) were evaluated in sub-
surface, pre-planting application. Only EPTC and (EPTC/
2,4-D) provided good control of annual weeds. R-4572 controlled annual weeds
except broadleaf species. No chemical or combination provided both good general
crop tolerance and effective weed control. (Tables 3 to 9, inc.)

In pre-emergence application, many chemicals effectively
controlled annual weeds: Banvel D, (CDAA / CDEC), CDEC, EAP 2020, (EAP 2000
applied over CDAA or CDAA / CDEC or CDEC or EPTC), FW-925, Herb. 976, Hyvar,
NaPCP, and SD 7961. Good control of annual grasses but not sedges or broadleaf
weeds was provided by: (Bayol 35 / 2,4-D), (Bayol 38 / 2,4-D), RC-2990, SD 1549,
and TD 282. Dacthal, diphenamid, trifluarlin and U-4513 effectively controlled
all annual weeds but sedges. Annual grasses and sedges but not broadleaf weeds
were controlled by: Dacamine, (EAP 2000 over CIPC), EPTC, (EPTC / 2,4-D),
N 2547, N 3291, OMU, R 1870, R 4461 and SD 7585. Of 50 chemicals or combinations
applied in 75 pre-emergence treatments only the following afforded good general
crop tolerance with promising annual weed control: CDEC, Dacthal, diphenamid,
FW-925, N 2547, N 3291, R 1870, R 4461, trifluralin, and U-4513. (Tables 10 to
16 and 17 to 23, inc.)

Three herbicides were applied as 9 emergence appli-
cations. Solan was less phytotoxic than the DPA formulations tested. The DPA
formulations did not demonstrate similar activity. Differences in tolerance
among individual crops and weeds (especially sedges) were striking. (Tables 17
to 23 inc.)

Thirty-two chemicals or combinations were applied as
61 treatments post-emergence to crops and annual weeds. CP 41142, CP 41329, DPA-
Rogue, DPA-Stam-34, Herb. 976, Hyvar, Lorox and paraquat effectively controlled
all annual weeds. Good control of annUal weeds-except sedges was provided by
TD-282. Promising crop tolerance with promising weed control was obtained with
SD 6623. (Tables 24 to 35 inc.)

N.B. Some crop seed had commenced germination but no seedlings were visible when
pre-emergence treatments were applied. Emg in the above table indicates
that cotylendons were enclosed in the seed coat or that cotyledons were not
unfolded; cotyledons were from 1/8 to 3/8 in above ground ~n the most
advanced plants. .
