海盐县成功研究新农药取代甲胺磷防治纵卷叶螟新技术取得明显的经济和社会效益,目前这一新技术已在全省推广使用农田面积达400万亩。用甲胺磷防治水稻纵卷叶螟,既造成稻米农药污染,又大量杀伤天敌,破坏生态平衡,一直是浙江省植保界面临的难题。海盐县从1998年起对取代甲胺磷防治水稻纵卷叶螟技术进行专题研究,采用毒死蜱与乙酰甲胺磷混配剂防治纵卷叶螟,成功地解决了这一全省性的农业技术难题。
Haiyan County successful study of new pesticides to replace methamidophos to prevent the new technology of leafroller to obtain significant economic and social benefits, the current new technology has been the province to promote the use of farmland area of 400 mu. Prevention and control of rice leaf roller with methamidophos not only caused the pollution of rice pesticides, but also destroyed the natural enemies in a large amount and destroyed the ecological balance. It has always been a challenge for the plant protection community in Zhejiang Province. Haiyan County from 1998 on the substitution of methamidophos for prevention and control of rice leaf roller technology research projects, the use of chlorpyrifos and acephate mixed prevention and control of leaf roller, the successful solution to the province’s agricultural technology problem.
