我省近年来稻飞虱在水稻后期严重发生,造成较大的损失。有些地区反映,使用常用农药防治效果不高,需要增加施药量和次数,因此而造成浪费和污染。为了解决这个问题,我们于1975年在花县新华公社新街、三华大队和东莞县横沥公社月塘大队,应用常用农药和新农药进行了大田防治试验示范。通过试验得出一些农药的田间用量和防治效果。
In recent years, our province rice planthopper occurred seriously in the late rice, resulting in greater losses. In some areas, the use of commonly used pesticides has been shown to be ineffective in controlling and controlling the pesticides. Therefore, it is necessary to increase the dosage and the number of pesticides to be used, resulting in waste and pollution. In order to solve this problem, we experimented and experimented in field prevention and control with commonly used pesticides and new pesticides in 1975 in Xinhua Commune Xinhua Street, Sanhua Brigade and Hengtong Commune Yuetang Brigade in Hengli County, Huaxian County. Through experiments, we can draw some pesticide field dosage and control effect.
