Abstract

Normal field applications of both terbufos and nicosulfuron can cause decreased corn tolerance to nicosulfuron because terbufos inhibits nicosulfuron metabolism. In greenhouse studies, applications of 2,4-D at 0.07, 0.14, and 0.28 kg/ha with nicosulfuron reduced terbufos induced foliar injury by more than 50%. Plants treated with nicosulfuron, terbufos, and 2,4-D had significantly higher shoot dry weights than those treated with nicosulfuron and terbufos. When 2,4-D was applied sooner than 24 h before nicosulfuron application or later than 24 h after nicosulfuron application, it did not prevent the interaction. Uptake of 14C-nicosulfuron was increased by the presence of terbufos but was unaffected by 2,4-D. Translocation of 14C-nicosulfuron was low with the highest amounts occurring in the nicosulfuron plus terbufos treatment. Terbufos reduced metabolism of nicosulfuron at 4 and 24 h after treatment compared to plants without terbufos. Metabolism of nicosulfuron in plants treated with terbufos was increased by 2,4-D to a rate equivalent to that in plants not treated with terbufos.
