Oiclofop, metsulfuron, 2, 4-0 Na, diflufenican, clodinafop, fenoxaprop, tralkoxydim and isoproturon applied in wheat did not exhibit any adverse effect on various kharif crops of mungbean, maize, cowpea, pigeon pea, pearl millet and cotton. Chlorsulfuron at 30 g ha" sprayed in wheat had no residual effect on mu,!gbean but at 60 and 120 g ha" had residual toxicity to mungbean. Compared to mungbean and cotton, maize was more sensitive to chlorsulfuron. Sulfosulfuron at 25 g ha" and pendimethalin at 1500 g ha" applied in wheat also caused residual toxicity to maize but not to mungbean and cotton. Metribuzin at 300 and 400 g ha" caused significant residual toxicity to mungbean and maize, and at 400 g ha" to cotton. Chlorsulfuron, sulfosulfuron, metribuzin and pendimethalin significantly reduced the density and dry weight of Trianthema portulacastrum at 210 days after treatment.
