Screening of Antagonistic Trichoderma Strains to Enhance Soybean Growth.

ABSTRACT: This study investigates the isolation and screening of Trichoderma strains that exhibit antagonistic properties against soybean root-infecting Fusarium species, particularly F. oxysporum. From soybean rhizosphere soil, 37 antagonistic Trichoderma strains were identified using the plate confrontation method, demonstrating inhibitory effects ranging from 47.57% to 72.86% against F. oxysporum. Strain 235T4 exhibited the highest inhibition rate at 72.86%. Molecular identification confirmed that the strains belonged to eight species within the Trichoderma genus, with notable strains promoting soybean growth in greenhouse tests. In pot experiments, the application of Trichoderma significantly reduced the disease index of soybean plants inoculated
