【摘要】 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。更多还原

【Abstract】 The effectiveness and application methods of pesticides against steneotarsonemus sp. were studied in1998. The results showed that the effectiveness of amitraz 20EC -, abamectin 1.8EC, pyridaben 15EC and fenbutatin oxide 25WP were from 77.38% to 84.18% . From elongation stage to heading stage of rice, the miticides should be sprayed for 2 - 3 times. It is unnecessary for mixing the miticides with fungicides. The integrated control methods were available, mainly including the alternate application of miticides and planting rice varieties with resistance to mite.更多还原
