研究包虫清(有效成分:氟虫腈、杀虫单)种衣剂不同包衣方式处理水稻种子对水稻生长前期主要害虫的控制效果。结果表明,不同处理对稻蓟马、稻飞虱防治效果达90%以上,持效期达30d以上。其中包衣旱育处理对三化螟、二化螟控制效果达85%以上。包虫清种衣剂对水稻种子、植株和稻田的主要蜘蛛较安全。
To study the control effect of different coating methods on the main pests of rice in the early stage of rice growth by using the seed coating of hydatid (the effective component: fipronil and insecticide single). The results showed that the control effects of different treatments on the rice thrips and planthoppers reached more than 90%, and the persistence period reached more than 30 days. Among them, the control effect of coating dry-up treatment on Borer borer and Chilo suppressalis reached more than 85%. Hydatid seed coating on rice seeds, plants and paddy fields of the main spider safer.
