扬州地区水稻历年受四虫三病危害甚为严重。以往由于防治指标偏紧,施药次数多,防治面积大,农药用量逐年增加,从而带来了害虫抗药性,次生害虫猖獗,有益生物减少,农产品残毒超标,环境污染严重和人畜中毒事故增多等一系列问题。为解决这些问题,我们于1982～1984年通过协作研究,逐步建立起一整套行之有效的水稻病虫综合防治体系,其技术要点如下。 Yangzhou rice over the years by the four pests disease is very serious. In the past, due to the tight prevention and control indicators, the large number of pesticides applied and the large area for prevention and treatment, the amount of pesticides used increased year by year, resulting in the resistance of pests, the rampant secondary pests, the reduction of beneficial organisms, the excessive remnants of agricultural products, the serious environmental pollution and the increase of human and animal poisoning accidents And a series of questions. In order to solve these problems, we gradually established a set of well-established integrated pest control systems for rice diseases through the collaborative research from 1982 to 1984 with the following technical highlights.
