Control Efficacy of 5 Biopesticides Against Corn Fall Armyworm
本文以'中糯二号'玉米品种为试验材料,比较了5种生物农药对玉米草地贪夜蛾的防治效果.结果表明:喷施1 500 g/hm2 10亿PIB/mL斜纹夜蛾核型多角体病毒悬浮剂、750 g/hm2 20亿PIB/mL甘蓝夜蛾核型多角体病毒悬浮剂防治玉米草地贪夜蛾效果最佳,建议在融安县玉米种植中大力推广及应用.
This study employed the'Zhongnuo No.2'corn variety as experimental material to evaluate the efficacy of five biopesticides against the fall armyworm(Spodoptera frugiperda)in corn fields.Results indicated that the application of 1 500 g/hm2 of 100 million PIB/mL Spodoptera frugi-perda nuclear polyhedrovirus(NPV)suspension and 750 g/hm2 of 200 million PIB/mL Spodoptera in-cisana NPV suspension demonstrated the highest control efficacy.These formulations are recommended for widespread adoption in corn cultivation across Rong'an County.
