设施蔬菜烟粉虱无公害防治技术研究

Pollution Prevention Techniques Against Bemisia tabaci Gennadius on Facility Vegetables

以22%敌敌畏烟剂、10%吡虫啉WP、2%阿维菌素EC、黄板不同方式组合,研究不同组合处理对设施烟粉虱的防治效果。结果表明:10%吡虫啉WP与2%阿维菌素EC按1∶1比例混合3 000倍液喷雾,对烟粉虱表现出了较好的速效性和迟效性;在黄板诱杀的基础上,进行敌敌畏烟熏,1、3、7d的防效均在70%以上,效果优于单纯使用化学农药;在黄板诱杀的基础上进行化学药剂喷雾,1、3、7d的防效均在80%以上,达到了理想的防治效果;在烟粉虱爆发时,可考虑化学药剂喷雾、烟熏、黄板诱杀同时进行,7d后防效可达98.5%以上,但要密切注意作物长势,以免发生药害。

With different combination of 22% Dichlorvos smoke agent,10% Imidacloprid WP,2% avermectins and yellow traping,the effect of different combination on the prevention of Bemisia tabaci Gennadius were studied.The results showed that sprayed by mixture of 10% imidacloprid WP and 2% abamectin EC 3 000 times,showed a good quick and delayed result against Bemisia tabaci Gennadius;Smoking for dichlorvos on the basis of yellow panel trapping,1,3,7-day control effect were more than 70%,effect was better than the use of chemical pesticides;Chemical spraying on the basis of yellow panel trap,1,3,7-day control effect were more than 80%,achieved the desired control effect;In the outbreak of Bemisia tabaci Gennadius,may consider chemical spraying,smoking and yellow board traping at the same time,effective defense can up to 98.5% after 7 days.But must pay close attention to crop and avoiding injury.
