Abstract
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.关键词
