Entomopathogenic infection ability of low land rice (Oryza sativa L.) cultivation from Ogan Komering Ilir regency

Abstract

Entomopathogenic fungi are biological agents important in suppressing or regulating pest populations in agricultural ecosystems. This study aimed to determine the ability to infect entomopathogens from lowland rice (Oryza sativa L.) cultivation from the Ogan Komering Ilir District. This research was conducted in the Pest and Plant Diseases Laboratory, Faculty of Agriculture, the University of Palembang, from February to May 2022. The study used a Completely Randomized Design (CRD) method consisting of 5 treatments, namely PS1 = mortality of bait insects three days after infestation (dai), PS2 = bait insect mortality six dai, PS3 = bait insect mortality nine dai, PS4 = bait insect mortality 12 dai, PS5 = bait insect mortality 15 dai and five replicates. This study concluded that the entomopathogenic fungus found in lowland rice (O. sativa L.) from Ogan Komering Ilir Regency was Beauveria bassiana and could infect the highest bait insect mortality on day nine after infestation.
