B型烟粉虱是近年侵入我国、为害许多作物的暴发性害虫,应用针对性强的高效农药,是一项控制其危害的必要手段。浙江省温州、台州、杭州等地农技部门,采用高含量吡虫啉和农用矿物油防治B型烟粉虱,对控制其发生、为害起到了很大的作用。鉴于农用矿物油不仅对烟粉虱致死效果明显,而且比一些广谱性化学杀虫剂副作用小,在今后B型烟粉虱药剂防治中可广泛应用。现将农用矿物油应用技术介绍如下:
B-type whitefly is invaded into our country in recent years, the outbreak of pests of many crops, the application of highly targeted and efficient pesticides, is a necessary tool to control their harm. Zhejiang Province, Wenzhou, Taizhou, Hangzhou and other agricultural technology departments, the use of high levels of imidacloprid and agricultural mineral oil to control the B-biotype Whitefly, to control its occurrence, damage played a significant role. In view of the fact that agricultural mineral oil is not only obviously lethal to Bemisia tabaci, but also has fewer side effects than some broad-spectrum chemical pesticides, it can be widely used in the future control of B-type B. tabaci. The application of agricultural mineral oil technology is as follows:
