噻螨酮等新农药防治叶螨试验应用技术研究

Applying Techeniques of New Pesticidesagainst Leafmite

作者于１９９１～１９９４年进行２５种农药防治果树叶螨田间药效试验。结果表明，５％噻螨酮乳油、２０％哒螨灵可湿性粉剂、５％唑螨酯悬浮剂防治果树叶螨幼、若、成螨效果均在９３．５％以上，５％噻螨酮乳油防治卵效果为９３．９％三种农药材果树叶螨的防治效果都优于对照药剂。

Pesticides were tested to control leaf mite in or-Chard during 1991～1994.The efficiency of 5%hexythiazoxEC,20%pyridben WP and 5%fenproximates reached 93,5%.the effect of 5% hexythiazox EC to control egg of mite was92.9%. The three pesticides gave better control results thanthose of conventional insecticides.
