田间对比试验结果表明:0.6%印楝素防治效果较其它3种当地常规药剂要差,药后10天防效仅为61.4%,而25%三唑锡可湿性粉剂、20%哒螨灵可湿性粉剂、1.8%阿维菌素乳油对防治叶螨效果较好,药后10天防效分别为99.8%、99.4%、98.1%,生产中可交替使用。但考虑0.6%印楝素为植物源农药,可与其它几种药剂混合使用或者在发生较轻时使用,减缓叶螨抗药性,保证产品安全。 The results of field trials showed that the control effect of azadirachtin 0.6% was worse than that of the other three kinds of local conventional drugs, and the control effect was only 61.4% on the 10th day after treatment, while the 25% azadirachtin WP and 20% pyridaben Wettable powder and 1.8% avermectin EC had good effect on spider mite prevention and control. The control effects on the 10th day after spraying were 99.8%, 99.4% and 98.1%, respectively, and could be used interchangeably in the production. However, considering 0.6% Azadirachtin as a plant-derived pesticide, it can be used in combination with several other medicaments or when it is mild, to slow down the spider mite resistance and ensure product safety.
