Abstract: The Jilin Academy of Agricultural Sciences screened the highly virulent Beauveria bassiana strain against the corn borer larva, and coworked with Jilin Bada pesticide Co., Ltd. to develop 40 billion spores/g of Beauveria bassiana wettable powder. This product can be used to controlling the corn borer larva on field by manual or mechanical sprayer during the first generation (big bell mouth stage of maize) and the second generation (ear stage of maize). The dosage of this product was 100—120 g/acre, and the control effect was above 61% after 14—20 d, it has a longer duration.
