Summary
Logarithmic, tank-mixed combination application of CflECand CDM, CDEC
and CIPC, CDAAand CIPC, CDID and Solan, and Dacthal and SGlan showed that
CDID and CDAAhad promise for good weed control wit.hout damage to a wide
range of seeded vegetable crops. CIPC in combination With CDID proved relatively
toxic. Solan and Dacthal gave excellent results on carrots.
In an extensive follow-up test of CDID and CDAAcombinations, it was
shown that beets, spinach, tomatoes, carrots and, perhaps, crucifers offer
opportunity for safe usage. Lettuce proved too susceptible to CDAA.
Weed control as measured by heavy populations of red root pigweed,
purslane, crabgrass and barnyard grass, was markedly improved by CDEC-CDAA
combinations even at relatively low dosages.
Considerable more work needs to be done in the area of herbicide combinations
for vegetables under a wide range of soils, environment, and
weed specie populations. However, it appears that CDECand CDAAoffer a promising
start.
