以保护农业生态环境、有效控制病虫危害为目标，从提高测报准确率、适当放宽防治指标、限制使用高毒高残留农药等方面入手，制定病虫总体综防模式，使病虫防治由高频次、多量序、单靶体转变为低频次、单量次、多靶体，从而达到减少用药次数降低农药用量、减轻环境污染的目的。 In order to protect the agro-ecological environment and effectively control pests and diseases, the overall mode of pest and disease control should be formulated from the aspects of improving the accuracy of survey and reporting, appropriately relaxing control indexes and restricting the use of highly toxic and highly residual pesticides. Frequency, multi-order, single-target into low-frequency, single-dose, multi-target, so as to reduce the frequency of medication to reduce the amount of pesticides and reduce environmental pollution purposes.
