近年来,为了解决生物防治与化学防治的矛盾,减少化防面积,保护和利用自然天敌,提高生态效益,各地通过试验示范,试图寻求一种既能有效地控制害虫危害,又不杀伤天敌;既有药效的持久性,又不污染环境的新农药的品种或剂型。据我们三年来试验示范结果证明,安徽省化工研究所研制的3％乙基硫环磷颗粒剂,具有上述诸功能,是目前较为理想的防治棉花苗铃期害虫的农药品种。
In recent years, in order to solve the contradiction between biological control and chemical control, reduce the area of chemical prevention and prevention, protect and utilize natural enemies, and enhance ecological benefits, various localities try to find a way that can not only effectively control pests but not kill natural enemies through experiment and demonstration, Varieties or formulations of new pesticides that are both persistent and non-polluting. According to our three years of pilot demonstration results show that the 3% ethylthiocyclic phosphorus granules developed by Anhui Institute of Chemical Industry, with these features, is currently the ideal pesticide variety to control cotton pests in the seedling and boll stage.
