防治水稻病虫害的生物农药登记情况和特点分析

Analysis on Registration and Characteristics of Biological Pesticides for Controlling Rice Diseases and Pests

本研究通过查询中国农药信息网发现,截至2022年6月登记防治水稻病虫害的生物农药单剂有671条,混剂有515条,仅占水稻病虫害防治登记农药总量的17.7%;单剂中86.7%的产品为低微毒产品,仅有乙蒜素、阿维菌素、甲氨基阿维菌素苯甲酸盐的部分产品为中等毒性.在此基础上,本研究进一步分析了所有登记生物农药的有效成分、推荐剂量、安全间隔期、最大残留限量的特点等,总结了水稻生物农药使用技术,以期为水稻病虫绿色防控提供一定参考.

In this paper, the information of biological pesticides for controlling rice diseases and pests registered to China Pesticide Information Network were inquired. In these biological pesticides, 671 single-agent products and 515 mixtures were registered. Only 17.7 % of the total registered pesticides for controlling rice diseases and pests were biological pesticides. The 86.7 % of the single-agent products were slight toxicity or low toxicity products. Only some products of ethylicin, abamectin and emamectin benzoate were moderately toxic products. The effective components, recommended dosage, safety interval and maximum residue limit of all registered biological pesticides were further analyzed, and the application technology of rice biological pesticides was summarized, so as to provide some reference for the green prevention and control of rice diseases and pests.
