本文比较了用尼索朗5％乳油和10％浏阳霉素按1：1和1：2混配对柑桔叶螨[柑桔红蜘蛛（Panonychuscitri）和柑桔六点黄蜘蛛（Schizotetranychussexmaculatus）的防治效果：①施药三天后，杀螨灵A乳油2000×对红蜘蛛的防效为96％，与浏阳霉素10％乳油1500×相当，略优于尼索朗5％乳油1500×②持效性方面，杀螨灵A乳油的2000×在施药后50天对柑桔叶螨的防效仍维持85％以上，与持效好的原药5％尼索朗乳油1500×相当，而大大优于10％浏阳霉素1500×施用7天后的效果。③使用复配农药杀螨灵A乳油2000×防治柑桔叶螨的费用仅为使用5％尼索朗乳油1500×的一半，对柑桔生长无不良影响。

The control effect ivenesses against Panonychus citri and Schizotetranycbus sexmacu latus wete comparel between yesticide mixes Shamanlin A and Bemulsifiable concentrate, which were mixed with Nissorum 5% EC and LiuYangmycin10% EC respectively in the ratio of 1: 1 and 1: 2.
