Abstract

Field experiments were conducted at two locations in Georgia to evaluate wild radish control and soft red winter wheat tolerance of herbicides applied February 1 (one- to five-tiller stage) or March 1 (three- to seven-tiller stage). Bromoxynil controlled wild radish with no wheat grain or forage yield reductions in any experiment. Thiameturon controlled wild radish when applied at rates >0.02 kg/ha on March 1. Metribuzin, dimethylamine salt of 2,4-D, and dimethylamine salt of MCPA provided late-season control of wild radish. February 1 treatments of metribuzin reduced wheat stands at Plains. The difference was attributed to environmental conditions, wheat tiller number at application, and possibly to differences in soil fertility at planting. Metribuzin, thiameturon, dimethylamine salt of dicamba, MCPA, and 2,4-D reduced wheat forage yield at Tifton. Dicamba did not control wild radish and reduced grain yield when applied at a rate of 0.3 kg ai/ha on March 1.
