为明确20%呋虫胺可溶粒剂用于大田防治甘蔗螟虫和绵蚜的防治效果,广西农业科学院植物保护研究所开展了该药的田间药效试验。结果表明,在甘蔗下种时每公顷施用20%呋虫胺可溶粒剂180~240克,对苗期甘蔗螟虫的防效最高可达100%,对甘蔗绵蚜的防效均达95%以上,且持效期长,与25%噻虫嗪水分散粒剂的防效无显著差异,是防治甘蔗螟虫和绵蚜的高效低毒的理想药剂。
In order to clarify the control effect of 20% dinotefuran soluble granules on the control of sugarcane borers and cotton aphids in the field, the Institute of Plant Protection of Guangxi Academy of Agricultural Sciences carried out the field efficacy test of this medicine. The results showed that the control effect of 20% dinotefuran soluble granules 180 ~ 240g / ha on sugarcane was up to 100% for sugar cane stem borer at seedling stage, and 95% , And long duration, with 25% thiamethoxam water dispersible granules no significant difference in the control effect is to control sugarcane borers and cotton aphids high efficiency and low toxicity of the ideal agent.
