Abstract

In field studies conducted over 2 yr, POST applications of chlorimuron, imazaquin, fomesafen, or acifluorfen following PRE applications of clomazone, metribuzin, or metribuzin plus chlorimuron enhanced wild poinsettia control when compared with the PRE herbicides applied alone. Wild poinsettia control was highest for imazaquin compared with other PRE treatments and with the exception of fomesafen, applications of POST herbicides following imazaquin PRE did not improve weed control. With the addition of POST herbicides, soybean yields were generally not increased, but moisture content in one year and foreign material content both years were reduced. In other studies, early POST applications (2 to 8 cm) of fomesafen, imazaquin, acifluorfen, lactofen, and chlorimuron controlled wild poinsettia better than late POST applications (10 to 15 cm) in only one year. Soybean yields both years were generally similar regardless of herbicide application time.
