我国农作物主要病虫害有1500多种,特别严重的有几十种,它们此起彼伏地频繁发生成灾,在各地造成大量损失,是阻碍我国农业生产发展的突出问题之一。已往单纯大量使用化学农药防治病虫害带来了诸多负面影响;残留农药污染环境、危害人体健康;病虫害产生抗药性使防治成本增高;已被控制的害虫再度危害并发生新病虫害。我国在1975年把“以防为主,综合防治”定为新的植物保护工作方针,并从第六个五年计划开始连续把农作物病虫害综合防治技术研究列为同家科技攻关研究重点。
There are more than 1,500 major pests and diseases in our country and there are dozens of species that are particularly serious. Their frequent occurrences and disasters cause losses in many places, which is one of the prominent problems that hinder the development of agricultural production in our country. In the past, chemical pesticides used in large numbers alone had many negative impacts on pest and disease control. Residual pesticides polluted the environment and endanger human health. Insecticide resistance caused by pest and disease increased the cost of prevention and treatment. The pests under control were newly endangered and new pests and diseases occurred. In 1975, China put “prevention first, comprehensive prevention and control” as the new policy of plant protection. From the sixth five-year plan, the research on integrated pest-disease control technology has been listed as the focus of research on the same subject.
