In this study, 1308 <i>Trichoderma</i> strains were obtained from the plant rhizosphere soil, above-ground plants, and decaying wood from natural habitats in China. Among them, 49 <i>Trichoderma</i> strains showed a good inhibitory effect, especially against <i>Botrytis cinerea</i>, <i>Fusarium oxysporum</i>, and <i>Colletotrichum gloeosporioides</i> with inhibition rate above 85% in the dual culture test. Among these 49 strains, the 13 strains with broad-spectrum inhibitory effects also significantly promoted the seed germination of five crops (rice, cucumber, tomato, melon, and pakchoi) and root growth of four croBioMed research internationalScreening and Identification of <i>Trichoderma</i> Strains isolated from Natural Habitats in China with Potential Agricultural Applications.PMC8714372Hnky2019ZD-4Zhang FHou JManman ZWang RWang WXue MZhang CLiu TRen SChen DfalseScreening and Identification of <i>Trichoderma</i> Strains isolated from Natural Habitats in China with Potential Agricultural Applications.<i>Trichoderma</i> spp. are widely distributed in natural habitats and have been evaluated as a potential biocontrol agent (BCA) for disease control and plant growth promotion.
