[目的]采用简易包种法筛选有效防治油菜跳甲的化学药剂。[结果]杀虫单处理后平均保苗率在83%以上,而吡虫啉的防治效果最差,平均保苗率低于45%;三唑磷处理后出苗第9天,平均保苗率达85%;出苗第9天经吡虫啉.马拉硫磷的处理平均保苗率达88.79%;出苗第3天,氟虫腈.三唑磷混配剂处理后平均保苗率达89.64%;出苗第9天除氟虫腈.辛硫磷混配剂外,其余氟虫腈的混配剂处理后,平均保苗率在85%以上;杀虫单.辛硫磷混配剂处理后平均保苗率高于84%;出苗后第9天杀虫单.氟虫腈混配剂平均保苗率为93.43%。[结论]杀虫单和三唑磷单剂、吡虫啉.马拉硫磷混配剂、氟虫腈.三唑磷、氟虫腈.马拉硫磷、氟虫腈.杀虫单、杀虫单.辛硫磷的种衣剂对防治油菜跳甲在生产上有一定的应用价值。
[Objective] The research aimed to screen the effective chemical agents for preventing rape beetle by using simple seed packaging method. [Result] The average seedling protection rate of insecticide single treatment was over 83%, while the control effect of imidacloprid was the worst. The average seedling protection rate was less than 45%. On the 9th day after the triazophos treatment, the average seedling protection rate was 85% On the 9th day, the average seedling protection rate was 88.79% after treated with imidacloprid and malathion. On the 3rd day after emergence, the average seedling protection rate reached 89.64% after treated with fipronil and triazophos. Phoxim, the average seedling protection rate was more than 85% after the compounding agent of fipronil and the average seedling protection rate was higher than 84% After the 9th day insecticidal single, the average seedling protection rate of fipronil was 93.43%. [Conclusion] Single insecticide and triazophos, imidacloprid and malathion compound, fipronil, triazophos, fipronil, malathion and fipronil, insecticide single and insecticide Single phoxim seed coating on the prevention and treatment of rape beetle in the production of a certain value.
