粉尘剂农药是利用粉尘所特有的漂浮效应,使农药粉尘颗粒均匀落在果树叶面上。粉尘剂与烟剂、水剂相比,有以下优点:省力省工,防治彻底,还可以避免对附近植株造成药害和药剂有效成分热分解。不像烟剂那样要求严格密封,大棚薄膜即使有破漏也能使用此法,无须用水稀释农药,避免了棚室内空气湿度的增加。粉尘剂颗粒均匀地散落在果树的各个部位,防治效果极佳。
Dust agent Pesticide is the use of dust floating effect unique to pesticide dust particles evenly fall on the foliage of fruit trees. Dust agent and smoke, compared to water, has the following advantages: labor-saving and labor-saving, thorough control, but also to avoid causing injury to nearby plants and pharmaceutical thermal decomposition of active ingredients. Unlike the smoke that requires strict sealing, even if shed film leakage can use this method, without dilution of pesticides, to avoid the greenhouse air humidity increases. Dust particles scattered evenly in all parts of the fruit tree, excellent control effect.
