Uji Efektivitas Jamur Entomopatogen Beauveria bassiana untuk Mengendalikan Spodoptera frugiperda pada Tanaman Jagung (Zea mays L.)

Abstract

This research aims to determine the effectivenes of entomopathogenic fungus Beauveria bassiana in controlling Spodoptera frugiperda on maize. The research employs completely Randomized Design (CRD) method consiting of 5 treatments (Control, 15 grams of B. bassiana/100 ml, 30 grams of B.  bassiana/100 ml, 45 grams of B. bassiana/100 ml, and 60 grams of B. bassiana/100 ml) and 3 replications. The parameters observed are the mortality of Fall Armyworm (S. frugiperda), the incubation period, and changes in the behavior of Fall Armyworm (S. frugiperda). To analyze the mortality data of Fall Armyworm (S. frugiperda), the research employs an analysis of Variance (Anova) with a DMRT of 5%. In the meantime, data on the incubation period and behavior changes of Fall Armyworm (S. frugiperda) are analyzed using descriptive analysis. In reference to the research finding, a dose of 30 grams of B. bassiana/100ml dissolved in water has a significant effect on the mortality of S. frugiperda larvae with an average mortality of 3.74%, 4.16%, and 4.58% on days 5,6, and 7.
