化学农药发展至今,已有50多年的历史,其间虽然发生过多次引起世界范围关注和忧虑的事件,但今天在农业生产中所碰到的病虫草害问题,化学农药几乎大都可以与之抗争,不能不认为这是了不起的成绩。但选用什么农药又如何使用,既要发挥其长处又要尽量减低其副作用是十分重要的技术问题。现简单介绍几个防治虫害的新药,仅供参考,要在生产中使用必需经过试验和经过我国批准登记。
Chemical pesticides have been in existence for more than 50 years now. Although there have been many world-wide concerns and worries during the course of their production, the problem of pests and weeds confronted in agricultural production today is almost at a premium with chemical pesticides , Can not but think that this is a remarkable achievement. However, what kind of pesticide should be used and how to use it is a very important technical issue to both exert its strengths and minimize its side effects. Is a brief introduction of several new pest control drugs, for reference only, to be used in production must be tested and registered through our country.
