Efektivitas Jamur Beauveria bassiana dalam Mengendalikan Hama Ulat Grayak (Spodoptera frugiperda) pada Tanaman Jagung Manis (Zea mays Saccarata Strut)

Abstract

This research aims to know the effectiveness and effective dosage of Beauveria bassiana for controlling Spodoptera frugiperda pest on sweet corn plant. This research is carried out at the Laboratory of the Center for Agricultural Plant (BALINTAN) of Gorontalo Province and on Farmers' Land in Village, Telaga Sub-district, Gorontalo Regency. It starts from March to August 2023 using a randomized block design (RAK) with 4 replications and 3 treatments. There are 16 experimental units using the Beauveria bassiana fungus as a biological control agent. The treatments used are B0 (control/without Beauveria bassiana), B1 (100g/l Beauveria bassiana), B2 (10g/1 Beauveria bassiana, and B3 (200g/l Beauveria bassiana). Observation parameters are mortality, and intensity of armyworm pest. The data analysis technique uses analysis of variance (ANOVA) in a 5% level, and continues with the 5% DMRT test. The finding shows that the Beauveria bassiana fungus is effective in controlling the armyworm pest frugiperda. A dose of 200g/1 can cause a mortality of 85.39%, while the control (without Beauveria bassiana) can cause a mortality of 1.41%.
