试验研究,结果表明:20％螨克乳油1000倍、1.8％害极灭乳油4000倍、15％哒螨灵乳油3000倍、25％托尔克可湿性粉剂1000倍的防治效果在77.38％～84.18％之间;杀螨剂单用及与杀菌剂混用的防治效果差异不显著;一次施药的防治效果不理想。并提出在水稻圆秆期至破口期喷施2～3次杀螨剂,以种植抗螨品种和药剂防治为主的综合防治技术。 The results showed that: the control efficacy of 20% mitek EC was 1000 folds, 1.8% ECK 4000 folds, 15% pyridaben EC 3000 folds, and 25% TCK WP 1000 folds was 77.38% ~ 84.18 %; Acaricides alone and mixed with the fungicide control effect was not significant difference; a pesticide control effect is not satisfactory. And put forward in the round corn stalks to the breach of the mouth spraying 2 ~ 3 times acaricide to plant anti-mite species and drug prevention and control based integrated control technology.
