Field Efficacy Trials of 10 Cyantraniliprole OD against Phytomyza horticola Gourean

摘要

In order to screen effective insecticides against Phytomyza horticola(Gourean),a comparative trial on the control efficacy of 10%cyantraniliprole OD and 75%cyromazine WP was conducted,and the optimal dose of 10%cyantraniliprole OD was determined.The results showed that 10%cyantraniliprole OD sprayed at the dosages of 375-450 mL/hm2 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/hm2.The yield increase rates of 10%cyantraniliprole OD were 8.39%-13.46%.
