| Abstract/Contents: | "The effect of chlorsulfuron {2-chloro-N-[[(4-methoxy-6-methyl-1, 3, 5-triazin-2-yl) amino] carbonyl] benzenesulfonamide} on the phytotoxicity of postemergence applications of the methil ester of diclofop {(+-)-2-[4- (2,4-dichlorophenoxy) phenoxy] propanoic acid} to Italian ryegrass [Lolium multiflorum (Lam.) #3 LOLMU] was investigated in field and greenhouse experiments. The addition of chlorsulfuron (14.8 g ai/ha field, 12.4 g/ha greenhouse) to 0.90 kg/ha diclofop reduced Italian ryegrass control 27% in the field and increased Italian ryegrass fresh weights in the greenhouse more than twofold over diclofop alone. The antagonism was more evident when combinations were used to treat Italian ryegrass in the three-leaf stage than the two- or four- leaf stage. Sequential applications yielded results similar to tank mix combinations. Chlorsulfuron and diclofop were approximately 400 and 50%, respectively, more active on Italian ryegrass when applied preemergence than when applied postemergence. Combinations of chlorsulfuron and diclofop applied preemergence to Italian ryegrass resulted in additive responses." |
