Abstract
Ryegrass ( Lolium multiflorum Lam. # LOLMU) control in wheat ( Triticum aestivum L.) using chlorsulfuron {2-chloro- N -[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl) amino] carbonyl] benzenesulfonamide} at 35 g ai/ha was significantly higher when applied preemergence (pre) than early postemergence (poe) to ryegrass with two to four leaves and wheat with three to five tillers. Metribuzin [4-amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4 H )-one] applied at 420 g ai/ha early poe controlled more than 95% of the ryegrass, but control was unacceptable when the same rate was applied late poe when the ryegrass was at midtiller and wheat at full tiller. Wheat leaf burn, stunting, and stand reduction occurred where metribuzin was applied early poe but yields were not affected. Ryegrass control was excellent where diclofop {(±)-2-[4-(2,4-dichlorophenoxy)phenoxy] propanoic acid} was applied early poe at 560 g ai/ha. Wheat yields, averaged over years, for early poe applications of chlorsulfuron at 35 g/ha, metribuzin at 280 and 420 g/ha, and diclofop at 560 g/ha were 22, 22, 24, and 20% higher, respectively, than the untreated stands. Injury associated with the herbicide treatments was not observed on soybeans [ Glycine max (L.) Merr.] planted following wheat.
