POTENSI CENDAWAN ENTOMOPATOGEN (Metarhizium sp. dan Beauveria bassiana) TERHADAP TINGKAT MORTALITAS LARVA ULAT GRAYAK JAGUNG (Spodoptera frugiperda)
Potential of Entomopathogenic Fungi (Metarhizium sp. and Beauveria bassiana) on Mortality Rate of Corn Armyworm Larvae (Spodoptera frugiperda)
Keywords:
Entomopathogenic, mortality, Spodoptera frugiperdaAbstract
The purpose of this study is to determine the effect of the use of entomopathogenic fungi (Metarhizium sp. and Beauveria bassiana) on the mortality of S. frugiperda in corn and to determine the concentration of entomopathogenic fungi that are more effective on the mortality of S. frugiperda in corn. The research was carried out by the South Sulawesi Food and Horticulture Crop Protection Center, IP3 OPT Wil Biological Agency Laboratory. 5 Pinrang, Jalan Poros Pinrang Rappang km. 12 which lasted for 2 months, from the beginning of February-March 2025. The experiment used a Complete Random Design Scheme consisting of 7 (seven) treatments with 3 (three) replicates. Treatments include P0 (Control without application of entomopathogenic fungi), P1 (Metarhizium sp. with a concentration of 5 grams/500 ml of water), P2 (Metarhizium sp. with a concentration of 7.5 grams/500 ml of water), P3 (Metarhizium sp. with a concentration of 10 grams/500 ml of water), P4 (Beauveria bassiana with a concentration of 5 grams/500 ml of water), P5 (Beauveria bassiana with a concentration of 7.5 grams/500 ml of water), P6 (Beauveria bassiana with a concentration of 10 grams/500 ml of water). The follow-up test uses a True Honest Difference level of 0.05. The results showed that there was an effect of the use of Entomopathogenic Mushrooms on the mortality of S. frugiperda on the concentration of Metarhizium sp, P3 mushrooms showing a better influence on mortality and death rate of S. frugiperda
