Abstract
The main pest of rice plants that attacks in the generative phase and can cause crop failure is Leptocorisa acuta. L. acuta attacks rice plants by sucking rice seeds during the milk ripening phase. This pest control still uses chemical pesticides. The use of chemical compounds at the farm level is very high which has the potential to damage the environment and residues in agricultural products so that control efforts are needed by utilizing the entomopathogenic fungus Metarhizium anisopliae. This study aims to determine the effect of M. anisopliae fungal mortality against L. acuta. The results showed that all treatments with M. anisopliae were significantly different from the control. The highest percentage of mortality was found in the treatment of the fungus M. anisopliae at a dose of 60 grams / l. water was 100% with an average time of death on day 3 after application and an average growth rate of 2.25 after L. acuta died. In 50 gram / l treatment. water and 40 grams / l. of water, respectively, the percentage of mortality was 100% with an average time of death 3.25 and 3.5 days with an average growth fungus rate of 2.5 after L. acuta died.
