粉尘剂是由农药原药与惰性粉(如滑石粉)等经过特殊工艺(气流粉碎技术)加工而成的、具有一定规格的新剂型农药。粉尘法是借助器械,利用粉尘剂防治病虫,是专用于棚室作物的一项新技术。它是利用粉尘的飘翔效应,使农药粉尘颗粒在棚室空间自由、均匀地落到作物上,起到防治病虫害的作用,同时又能降低棚室内湿度,减少病害发生的机会,具有防治病害的功能。粉尘剂防治病害省时、省工、省力。另外,对使用条件也不严格,即使大棚薄膜有小破口也可照常施用。
Dust agent is the original pesticide and inert powder (such as talcum powder) through a special process (airflow crushing technology) processing, with a certain size of the new formulations of pesticides. Dust method is the use of equipment, the use of dust agent pest control, is dedicated to greenhouse crops a new technology. It is the use of dust floating effect, so that pesticide dust particles in the greenhouse space free and evenly fall to the crop, play a pest control role, while reducing greenhouse indoor humidity and reduce disease opportunities, with disease prevention and control Function Dust agent disease prevention and time saving, labor-saving, labor-saving. In addition, the conditions of use is not strict, even if a small shed film shed can be used as usual.
