<i>Trichoderma</i> <i>asperellum</i> Ta1 Alleviates Root Rot Caused by <i>Fusarium solani</i> and Promotes the Growth of <i>Panax notoginseng</i>.

ABSTRACT: Panax notoginseng is a traditional medicinal and food-homologous plant in China; however, root rot, primarily caused by Fusarium solani, has become a devastating disease that severely compromises the yield and quality of P. notoginseng. In this study, a strain of Trichoderma asperellum (designated as Ta1) was isolated from the rhizosphere soil of healthy P. notoginseng. In vitro, Ta1 exhibited strong antagonistic activity against F. solani, with a growth inhibition rate of 65.53%, and the spore germination of F. solani was inhibited. In pot experiments, Ta1 reduced the incidence of root rot, and the biocontrol efficiency was around 59.55%. Additionally, Ta1 improved the growth vigor of P. notoginseng plants, resulting in significant i
