Efficacy Study of the Commercial Biofungicide Trichoderma viride (Ami Trichostar) Against Fusarium wilt in Arachis hypogaea L

The aim of this study is to investigate the effectiveness of Ami Trichostar, a biocontrol product that contains Trichoderma viride, in reducing the occurrence of Fusarium wilt in Arachis hypogaea L. (groundnut) plant.Using dual culture and agar well diffusion techniques, in vitro experiments were conducted to evaluate the antagonistic potential of Trichoderma viride against Fusarium oxysporum.Studies, including crop yield, germination percentage, survival rate, and the number of dried plants, were assessed through field experiments.Results determined that in both the agar well diffusion experiment and the dual culture assay, Trichoderma viride produced zones of inhibition against Fusarium oxysporum that measured 34.2 6 mm and 34.3 4 mm, respectively.Comparing Ami Trichostar treated plants to untreated ones, the application greatly increased germination percentage, survival rate, incidence of dried plants, and crop production.The application of Ami Trichostar as a biocontrol agent, administered in powder form at a rate of 1 kg/acre, significantly decreased Fusarium wilt incidence while boosting seed germination and other plant growth indicators.
