 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been withdrawn.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.
