A SELECTIVE ANTIDOTE FOR PREVENTION OF EPTC INJURY IN CORN

Abstract

A new herbicide antidote, N,N-diallyl-2, 2-dichloro acetamide (hereafter referred to as R-25788) used in combination with EPTC (S-ethyl dipropylthiocarbamate), as seed treatments or as mixed sprays, protected corn (Zea mays L.) from herbicide injury in growth room and field trials. In growth room tests R-25788 gave partial protection from EPTC injury to sorghum (Sorghum vulgare Pers.) but not to winter rape (Brassica napus L.), turnip (Brassica rapa L.), white bean (Phaseolus vulgaris L.), redroot pigweed (Amaranthus retroflexus L.), lambsquarter (Chenopodium album L.), crabgrass (Digitaria sanguinalis (L.) Scop.), and green foxtail (Setaria viridis (L.) Beauv.). The antidote alone did not affect the crops or weeds.
