锐劲特(氟虫腈)是一种苯基吡唑类杀虫剂,杀虫谱广,对害虫以胃毒作用为主,兼有触杀和一定的内吸作用,其杀虫机制在于阻碍昆虫R-氨基丁酸控制的氯化物代谢。因此对飞虱、二化螟、纵卷叶螟等水稻害虫都有很高的杀虫活性,每亩用5%锐劲特30-40毫升,防效可达95%左右,持效期可达20-30天。此文将通过通州市的施药情况,来谈谈锐劲特防治二化螟的使用技术。
Fipronil (fipronil) is a phenylpyrazole insecticide, broad spectrum insecticide to stomach poisoning-based, both touch and certain endocytosis, the insecticidal mechanism is hindered Insect R-aminobutyric acid controlled chloride metabolism. Therefore, it has high insecticidal activity against rice pests such as planthoppers, rice stem borers and leafroll moth, with 30-40 milliliter per acre with 5% of fipronil, with the control efficiency of about 95% Up to 20-30 days. This article will Tongzhou application of the situation, to talk about the use of fipronil prevention and control of rice stem borer technology.
