| Popis: | Field research conducted for 3 yr evaluated weed control in glyphosate-resistant soybean with glyphosate applied alone and in mixtures with reduced rates of the broadleaf herbicides acifluorfen, CGA-277476 (proposed name: oxasulfuron), chlorimuron, fomesafen, or lactofen. Barnyardgrass was controlled at least 95% with glyphosate at 840 and 1,120 g ai/ha, and control was not antagonized with any of the mixtures. At 14 d after treatment (DAT), wild poinsettia and prickly sida were controlled at least 90% with all glyphosate treatments. Control remained greater than 90% 28 DAT in one of the 2 yr, but in the other year, wild poinsettia was controlled 80%, and prickly sida was controlled 43% with the high rate of glyphosate. Acifluorfen or fomesafen (210 and 315 g ai/ha), or lactofen (112 and 168 g ai/ha) applied with glyphosate increased wild poinsettia control to 91 to 95% and prickly sida to 60 to 83%. At 14 DAT, pitted morningglory control improved in most cases when acifluorfen, fomesafen, or lactofen was... |
