水稻稻纵卷叶螟是一种迁飞性害虫,是为害水稻的主要害虫之一。近年来,此虫在我国广大水稻种植区呈上升趋势,且出现了迁入批次增多,发生面积增大,虫口密度增高,为害损失增重。在生产实践中,水稻稻纵卷叶螟对许多农药产生了不同程度的抗药性,不仅达不到防治目的,更重要的是错过了防治适期,给水稻生产带来较大损失。为了寻找替代防治稻纵卷叶螟的理想药剂,北京绿色农华生物工程技术有限公司将其生产的甲维盐·氟铃脲10.5%WDG用于防治水稻田稻纵卷叶螟,并将甲维盐5%WDG、氟铃脲5%EC、阿维菌素1.8%EC作为对比进行药效试验,现将试验结果报告如下。
Rice leaf roller is a migrating pest, which is one of the major pests that damage rice. In recent years, the worm has been on the rise in the majority of paddy planting areas in our country, and there has been an increase in the number of immigrants, an increase in the area, the increased population density and the detrimental weight loss. In the practice of production, the rice leaf roller has many degrees of resistance to pesticides, not only failed to control the purpose, more importantly, missed the appropriate control, resulting in greater loss of rice production. In order to find an ideal substitute for the prevention and control of rice leaf roller, Beijing Green Agrochemical Biotechnology Co., Ltd. will be its production of a salt of hexaflumuron 10.5% WDG used to control rice leaf roller, and A Dimethicone 5% WDG, hexaflumuron 5% EC, avermectin 1.8% EC as a comparative efficacy test, the test results are reported as follows.
