NN‐DIALLYL‐αα‐DICHLOROACETAMIDE AS AN ANTIDOTE FOR EPTC AND OTHER HERBICIDES IN CORN

Summary. The efficacy of NN‐diallyl‐αα‐dichloroacetamide (R‐25788) as an antidote for reducing the injury of various herbicides in corn (Zea mays L.) was tested under controlled conditions in growth rooms. The application of R‐25788 to the soil as a pre‐plant incorporated treatment to corn significantly reduced the toxicity often out of twenty‐two herbicides tested. These ten herbicides were, in order of decreasing effectiveness of the antidote, EPTC, barban, sulfallate, vernolate, molinate, butylate, alachlor, pebulate, linuron and di‐allate. In quartz sand nutrient culture, R‐25788 was more effective as an antidote for barban applied to the foliage of corn than it was for barban applied to the roots.
