The results showed that 10% cyantraniliprole OD sprayed at the dosages of 375-450 mL/hm^2 had good control effect on P. horticola, which also increased the yield of fresh pea pods. At 15 d post spraying, the control effects of 10% cyantraniliprole OD against P. horticola were 81.98%-86.12% when sprayed at the dosages of 375-450 mL/hm^2. The yield increase rates of 10% cyantraniliprole OD were 8.39%-13.46%.展开更多
