| Abstract: | In order to provide guidance for the promotion of pretilachlor,trials were conducted to evaluate the weeds control effects of 300 g/L pretilachlor EC in throwing-seedling field and its influence on nutrient,rice yield and economic benefits.The results showed that 300 g/L pretilachlor EC had good control effects over 92% on Echinochloa crusgalli(L.) Beauv,Cyperus difformis L.,Monochoria vaginalis(Burm.F.) which reach.And after the application,the yield was increased by 20.38～30.62% compared with control.Application of pretilachlor EC at 300 g/L significantly saved labor and increase economic benefits,was an effective herbicide to control annual weeds in throwing-seedling rice field. |
