Abstract

Abstract: The control effects of 8 billion spores/milliliter CQMa421（Metarhizium anisopliae） dispersable oil suspensions of M. anisopliae produced by Chongqing Polymeric Bioengineering Co.,Ltd. on rice were verified, and the substitution products of chemical pesticides were found. The results show that the efficacy of M. anisopliae 8 billion spores per milliliters OD 60 mL per 667 m² can reach 35.57%~68.14% against rice planthopper,53.22% leaf preserving effect against rice leaf roller,and 60.73% effectiveness of comprehensive prevention and treatment measures against striped rice borer. The rate of growth rate achieves 28.4%. It can be popularized and applied as a substitute technology for chemical control in rice.

Key words: Metarhizium anisopliae CQMa421, rice pests, efficacy
