摘要: 针对天津地区水稻苗期病害发生的种类、病原、危害症状,以及近年来生产上出现的化学药剂防效降低和安全性差等问题,笔者选取8种针对水稻苗期病害使用频率较高的化学药剂进行室内毒力测定,明确了药剂的防治效果,给出了推荐使用药剂的种类及使用方法,以指导农民精准对靶施药,提高防治效果,减少化学农药用量。

Abstract: This paper described the occurrence of rice seedling diseases in Tianjin area, including the types, pathogens and symptoms of rice diseases, combined with the problems of poor control effect and safety of chemical agents in recent years. In this paper, 8 kinds of chemicals used frequently in rice seedling stage were selected for indoor virulence test, the control effect of the insecticides was determined, and the recommended pesticide types and methods were given. The purpose was to direct the farmers to accurately apply insecticides to the target, improve the control effect and reduce the amount of chemical pesticides.

Key words: rice, seeding disease, rice bakanae disease, rhizoctonia rot, chemical agent pesticides, toxicity determination
