Using dipping seedling method,we studied the effect of MSO GY-T1602 on 80% nitenpyram·pymetrozine WDG against rice brown planthopper.The results showed that adding GY-T1602 to 80% nitenpyram·pymetrozine WDG had high activity on 3 days old rice brown planthopper nymphs.The LC_(50) value added with 0.3%-0.6% GY-T1602 was obviously lower than that of 80% nitenpyram·pymetrozine WDG alone,which was 0.583 2 mg/L and 0.461 2 mg/L,respectively.GY-T1602 was also safe for rice.
