摘要
通过田间小区试验评价了广谱甘蓝夜蛾核型多角体病毒对草地贪夜蛾的防治效果,20亿PIB/mL甘蓝夜蛾核型多角体病毒悬浮剂用于防治草地贪夜蛾,每亩用量50~60 mL,药后7 d防治效果达到85%以上。2019年在江西省、四川省和贵州省推广应用44.9万亩。
Control efficacy of the wide-host range Mamestra brassicae nucleopolyhedrovirus against the fall armyworm,Spodoptera frugiperda,was evaluated in corn fields.The 2×109 PIB/mL Mamestra brassicae nucleopolyhedrovirus suspension at 50—60 mL per mu reached control efficacy of over 85%within 7 days post treatment.The product was used to control Spodoptera frugiperda on maize for 0.449 million mu in Jiangxi,Sichuan and Guizhou Province in 2019.
