磷胺是一种容易被植物吸收的、高效广谱性有机磷杀虫剂。具有触杀和内吸作用。对刺吸口器,咀嚼口器和蛀食性害虫有较好的防治效果。过去,用磷胺防治水稻螟虫的方法是直接施用原油,每亩用25毫升至50毫升,喷雾或喷雨防治,效果都很好。为了改进施用技术,1986年,我们使用2.5%磷胺粉剂防治水稻二化螟在全省13个县同时进行大面积示范,推广面积达6,500亩,取得很好的防治效果。
Phosphamide is a highly efficient broad spectrum organophosphate insecticide that is easily absorbed by plants. With touch and absorption effect. On the piercing mouthparts, chewing mouthparts and eating pests have a better control effect. In the past, the use of phosphate amine to control rice stem borers is the direct application of crude oil, per acre with 25 ml to 50 ml spray or spray prevention and treatment, the effect is very good. In order to improve the application technology, in 1986, we used 2.5% phosphorous amine powder to control rice stem borer in 13 counties throughout the province to carry out large-scale demonstration at the same time. The area of 6,500 mu was popularized and good control effects were achieved.
