摘　　要：2004—2005年在湖南安乡、醴陵进行了10％苯丁锡EC防治柑桔红蜘蛛的田间药效试验。结果表明，在红蜘蛛发生期用10％苯丁锡EC200—250mg／kg喷雾，药后1d的校正防效均在70．7％以下；药后3d的校正防效为87．2％-92．4％，药后7d的校正防效均在92．7％以上，药后15d的校正防效为95．3％-98．8％，药后30d的校正防效为82．0％-93．9％，优于或相当于对照药剂15％哒螨灵EC用75mg／kg处理的效果。In order to examine the effects of fenbutatin oxide 10% EC on controlling Panonychus citri in field, the experiment was carried out during 2004 - 2005 at Anxiang and Liling. The results showed that fenbutain oxide 10% EC with dosages of 200 - 250 mg/kg had and excellent effect to control the citrol red mite. The control effects was 70.7% on the first day after treatment and 87.2% - 92.4% on the third day, over 92.7% on the 7^th day and 95.3% - 98.8% on the 15^th day. The control effects reached 82.0% - 93.9% on the 30^th day. The control effects were similar to or better than those by using pyridaben 15 % EC with 75 mg/kg.
