The objective of this study was to prove the effect of 40% Chlorantraniliprole and Thiamethoxam on controlling of Asian Corn Borer in Jilin Province and its safety on maize. The experiment was carried out according to national standard. The results showed that effect was the same among different application method, but effect was enhanced when more dosage applied. When the dosage was 36.0~48.0 ga.i./hm², the effect was 38.8%~95.2%. It was concluded that the proper application method was either spraying 36.0~48.0 ga.i./hm² diluted in 375.0 L water or mixed it with sand at ratio of 1:50 and applied at 45.0 ga.i./hm² ~56.25 ga.i./hm².
