Controlling Soybean Insect Pests and Yield Losses with Entomopathogenic Fungi <i>Beauveria bassiana</i> and <i>Metarhizium anisopliae</i>

The objective of this study identifies the effective of <i>Beauveria bassiana</i> and <i>Metarhizium anisopliae</i> fungi as soybean pest control agents compared chemical in The objective of this study was to compare the effectiveness of Beauveria bassiana and Metarhizium anisopliae fungi as soybean pest control agents with chemical insecticides secticides. The experimental designed was randomized complete block design with 4 treatments: B1: Control, B2: Beauveria & Metarhizium fungi (50 g/L) weekly, B3: Beauveria & Metarhizium fungi (100 g/L) weekly and B4: Triazophos + Abamectin chemicals. The results showed the efficacy of Beauveria and Metarhizium fungi as biocontrol agents for soybean insect pests. Statistical analysis of plant height, pod number, seed weight, and pod damage revealed significant differences among treatments. Notably, Beauveria + Metarhizium at 50 g/ha significantly increased seed weight per plant (P < 0.05), while the 100 g/ha treatment maximized plant harvest numbers (P < 0.05). However, both fungal treatments exhibited no significant impact on pest population compared to the chemical control. This may be attributed to the spray application timing, coinciding with high morning sunlight, potentially affecting fungal conidia viability. Despite inconclusive pest control, the fungi-treated groups demonstrated enhanced plant growth and yield parameters, suggesting their potential as sustainable and environmentally friendly pest management alternatives. Further research is warranted to optimize application strategies and maximize their efficacy against soybean insect pests.
