6种杀虫剂对甘蓝小菜蛾的田间防治效果
|
摘要
为筛选防治甘蓝小菜蛾安全有效的杀虫剂,采用田间试验的方法,研究了3%阿维菌素水乳剂等6种杀虫剂对甘蓝小菜蛾的田间防治药效。试验结果表明,30 g/L顺式氯氰菊酯乳油22.5 g a.i./hm 2药剂处理对甘蓝小菜蛾药后3 d,8 d防效均达90%以上,其他药剂处理防效达80%以上,也具有良好的防治效果,可作为有效防治药剂交替使用,在试验用量下对甘蓝植株安全未出现药害和其他不良反应。
To screen safe and effective insecticides against Plutella xylostella, field trials were conducted to study the efficacy of 6 insecticides including 3% avermectin water emulsion. The results showed that the control effect of 30 g/L cis-cypermethrin EC with 22.5 g a.i./hm 2 on cabbage Plutella xylostella was more than 90% in 3 and 8 days after the treatment, and that of other agents was more than 80%, showing good effects as well. Thus, all seven agents could be used alternately as effective control agents, and there were no harmful effects and other adverse reactions on cabbage plants under the experimental dosage.
