Abstract: To improve the environmental friendliness of Quizalofop-p-ethyl EC and meet the need of high quality Quizalofop-p-ethyl EC, formula of 20% Quizalofop-p-ethyl EC was developed and the optimal formula was determined based on the traditional formula of EC. Herbicidal effects of environmental friendly 20% Quizalofop-p-ethyl EC and the imported herbicide were compared through field efficacy trials. The results showed that the main control indicators were in line with the requirements. Herbicidal effect of environmental friendly 20% Quizalofop-p-ethyl EC was better than that of imported herbicide significantly. Thus, environmental friendly 20% Quizalofop-p-ethyl EC can replace the imported herbicide to control grassy weeds.Key words: Quizalofop-p-ethyl; EC; Formula; Efficacy
