The field trial efficacy on cyantraniliprole 19% SC against Hydrellia griseola was evaluated. The results showed that the control effect was over 75% and the effect lasted for 20 days when it was sprayed 2 days before transplanting at concentration of 6 000-7 800 g/ha, and there was no significant difference from Thiamethoxam 25% SC（P＜0.05）. Both Cyantraniliprole 19% SC and Thiamethoxam 25% SC had meaningful control efficacy against H. griseola. The results of field experiments showed that Cyantraniliprole 19% SC was long persistent, convenient, lesscost and did not affect ecological environment when it was applied to control H. griseola.
