为探明9%12α-羟基鱼藤酮水乳剂对水稻纵卷叶螟、白背飞虱和褐飞虱的防治效果，进行了田间药效试验。结果表明：9%12α-羟基鱼藤酮水乳剂对上述3种害虫均有较好的防效。用药量为80~100 mL/667m2时，可有效防治稻纵卷叶螟低龄幼虫，具有防效较高和持效期较长的特点；用药量为100~120 mL/667m2时，可高效杀灭田间白背飞虱和褐飞虱，具有较好的速效性。因此，该药剂可推荐用于防治水稻纵卷叶螟、白背飞虱和褐飞虱。
為探明9%12α-羥基魚籐酮水乳劑對水稻縱捲葉螟、白揹飛虱和褐飛虱的防治效果，進行瞭田間藥效試驗。結果錶明：9%12α-羥基魚籐酮水乳劑對上述3種害蟲均有較好的防效。用藥量為80~100 mL/667m2時，可有效防治稻縱捲葉螟低齡幼蟲，具有防效較高和持效期較長的特點；用藥量為100~120 mL/667m2時，可高效殺滅田間白揹飛虱和褐飛虱，具有較好的速效性。因此，該藥劑可推薦用于防治水稻縱捲葉螟、白揹飛虱和褐飛虱。

In order to determine the control effect of 9% 12α-hydroxy-rotenone EW against Cnaphalocrocis medinalis Guenee, Sogatella furcifera and Nilaparvata lugens, a field experiment had been conducted. The results showed that 9% 12α-hydroxy-rotenone EW had a great control effect against these three pests showed above. When the dosage of 9% 12α-hydroxy-rotenone EW was 1 200~1 500 mL/hm2, it can control larva of Cnaphalocrocis medinalis Guenee effectively with high control efficiency and long duration; when the dosage of it was 1 500~1 800 mL/hm2, it can kill Sogatella furcifera and Nilaparvata lugens in field rapidly with high efficiency. Therefore, 9%12α-hydroxy-rotenone EW can be recommended to control Cnaphalocrocis medinalis Guenee, Sogatella furcifera and Nilaparvata lugens for rice.
