在基层时,多次听到人说,打了药,为啥虫子不死,或者,虫子一时少了,过些日子,又多起来,到底啥原因。针对这个问题,谈谈我的看法。 道理很简单,治虫就象医生给人看病一样,要“对症下药”,又同农民种庄稼一样,要“不误农时”。“对症下药”主要是根据某一种害虫的生物学特性、危害方式、危害虫态、龄期等情况选择防治效果最好的农药。“不误农时”在防治害虫可称作“适时防治”,这主要指抓紧害虫生活周期中的薄弱环节进行防治,也就是说,某一段时期内的某种虫态是不可错过的防治良机。
When I was at the grassroots level, I heard many people say that medicine was used to prevent the insects from becoming immortal or that the insects were temporarily out of control. In response to this question, talk about my view. The reason is very simple. The pest control is just like giving a doctor a doctor’s advice. It is necessary to “make the right prescription” and, like the peasants’ crops, they must “not be misbalanced by agriculture.” “The right remedy” is mainly based on the biological characteristics of a pest, the way to endanger the insect status, age and other conditions to choose the best prevention and control of pesticides. “Do not be wrong when farming” in the control of pests can be called “timely prevention and control”, which mainly refers to the vulnerability of pests in the life cycle of prevention and control, that is, some period of a certain state of insects is an opportunity to prevent and control.
