Everglades Station Mimeo Report EES64-1 September 1963

STATUS OF HERBICIDES FOR PEPPER AND TOMATO PRODUCTION
EAST COAST SAND SOILS/

J. R. Orsenigo2/

PEPPER
A. Previously cleared chemicals
RECOMMENDED None

Suggested None

B. Recently cleared chemicals
RECOMMENDED None

Suggested diphenamid (Dymid, Enide) 4 lb. active per acre preemergence
to direct-seeded pepper and weeds or post-transplanting
in weed free soil.

C. Promising chemical treatments (for direct-seeded pepper)
Neither recommended or suggested
CDAA (Randox) 4 lb. active per acre preemergence.
CDEC (Vegedex) 2 lb. active in 40 gpa mineral spirits as delayed
preemergence 2 3 days before pepper come-up.
CDEC (Vegedex) 2 lb. active PLUS solan (Solan) 2 lb. active per
acre as delayed preemergence 2 3 days before pepper come-up.
solan (Solan) 4 lb. active per acre as delayed preemergence 2 3
days before pepper come-up.
trifluralin (Treflan) 4 lb. active per acre preemergence.


TOMATO
A. Previously cleared chemicals
RECOMMENDED solan (Solan) 4 lb. active per acre as late preemergence
before direct-seeded tomato come-up or as directional lay-by
spray at same rate.

Suggested Mineral spirits at 30 40 gpa as late preemergence before
come-up of direct-seeded tomato.

PEBC (Tillam) 4 lb. active per acre to soil surface pre-
bedding or same rate applied after bedding to soil surface
and incorporated up to 2 inches deep immediately after
application. Seed may be drilled after incorporation.
NOTE: The Stauffer Chemical Company has withdrawn Tillam's
recommendation for preemergence weed control in direct-
seeded tomato and it may be available only on a grower
cognizance basis.

B. Recently cleared chemicals
RECOMMENDED None

Suggested diphenamid (Dymid, Enide) 4 lb. active per acre preemergence
to direct-seeded tomato or post-transplanting at same rate
in weed free soil.

C. Promising chemical treatments (for direct-seeded tomato)
Neither recommended or suggested
CDAA (Randox) 4 lb. active per acre preemergence.
CDEC (Vegedex) 4 lb. active PLUS solan (Solan) 2 lb. active per
acre preemergence.
trifluralin (Treflan) 4 lb. active per acre preemergence.

GENERAL COMMENTS

Rates given above are interms of pounds (Ib) active ingredient per sprayed
acre. Treatments are for water spray application except where specific exceptions
are indicated.
Recommended herbicidal treatments have established reliability. Suggested
herbicidal treatments have not been tested sufficiently to establish commercial
dependability and are suggested for LIMITED TRIAL USE ONLY for grower familiariza-
tion. Both recommended and suggested treatments have label clearance for the
application given.
Amiben (Vegiben) is cleared for post-transplanting sprays or granular lay-by
use local data are insufficient for status report.
CDAA (Randox) usually provides good grass control and mediocre broadleaf weed
control. Good soil moisture improves performance.
CDEC (Vegedex) usually controls broadleaf weeds better than grasses but per-
formance is erratic on sand soils. Good soil moisture improves performance.
DCPA (Dacthal) labelling for use preemergence to direct-seeded tomato has
been withdrawn. Control of broadleaf weeds and annual sedges inferior,
Diphenamid (Dymid, Enide) usually controls grass weeds effectively. Control
of broadleaf weeds and annual sedges is erratic and usually inferior,
PEBC (Tillam) is most effective under dry soil conditions and when incorporated,
It usually controls annual grass weeds and sedges. Broadleaf weed control is
erratic and often inferior especially where leguminous and solanaceous weeds are
common.
Solan (Solan) performance is improved by good soil moisture. It is more
effective against broadleaf weeds. Emerged, small grass and broadleaf weeds are
controlled.
Trifluralin (Treflan) is most effective against annual grass and broadleaf
weeds and rarely controls annual sedges adequately.

The activity of most preemergence herbicides is improved by adequate soil
moisture.
