Description :
Fusarium wilt, caused by Fusarium oxysporum f. sp. glycines, is one of threat to soybean (Glycine max). This study investigates the biocontrol potential of indigenous Trichoderma spp. formulated with different carrier materials, focusing on talc-based formulations for their efficacy under pot culture conditions. From thirty rhizospheric soil samples, twenty-five Trichoderma isolates were obtained, and three superior antagonistic strains (TR2, TR3, and TR23) were selected based on dual culture assays. These isolates were mass-multiplied using six carrier substrates (talc, lignite, charcoal, sawdust, compost, and fly ash), and their shelf life was evaluated over 180 days. Talc emerged as the most effective carrier, maintaining the highest colony-forming units (CFU/g) across all time intervals. The results suggest that talc-based formulations of native Trichoderma isolates, particularly TR2, offer a sustainable and eco-friendly alternative to chemical fungicides.
