5%啶虫·高氯EC防治番茄蚜虫的研究

Tests on Tomato Aphid Control with 5% Acetamiprid·High Chloride EC

近年来,番茄蚜虫在陕西发生严重,不仅为害植株,还能传播多种病毒病。为有效控制番茄蚜虫为害,筛选理想药剂,笔者选用5%啶虫·高氯EC、3%啶虫咪WP和4.5%高效氯氰菊酯EC进行防效试验。结果表明:5%啶虫·高氯EC675ml/hm2药后1d防效达85.73%,药后3d防效达96.41%,药后7d防效达91.35%,均高于对照药剂防效;5%啶虫·高氯EC600ml/hm2防效优于对照药剂3%啶虫咪WP600g/hm2,与4.5%高效氯氰菊酯EC390ml/hm2防效相当。由此可知,5%啶虫·高氯EC适宜防治番茄蚜虫,最佳使用剂量为600～675ml/hm2。

In recent years, the tomato aphids occurred seriously in Shanxi. It not only harm to plants, but also spread a variety of viral diseases. In order to ef- fectively control tomato aphid and screen the ideal pesticide, tests are conducted with 5% acetamiprid, high chloride EC, 3% acetamiprid WP, as well as 4.5% Ba- ta-Cypermethrin EC. The results show that, 1 days after spray pesticide, the con- trol effect of 675 ml/hm2 5% ac- etamiprid, high chloride EC was 85.73%; 3 days after application, the effect was up to 96.41%; 7 days after spray pesticide, the control effect was 91.35%. The con- trol effect of 5% acetamiprid, high chlo- ride EC 600 ml/hm2 is better than 3% ac- etamiprid WP. Thus, 5% acetamiprid. high chloride EC was fit for control tomato aphid, and the best pesticide ap- plication was 600-675 ml/hm2.
