Chaetomium spirotrichum 201 and application thereof

The invention provides chaetomium spirotrichum 201 and application thereof, and belongs to the technical field of biological control, the chaetomium spirotrichum 201 is preserved in Guangdong Microbial Culture Collection Center, and the preservation number is GDMCCNO: 63186; the chaetomium spiral is separated and screened from the root of the smooth vetch; the bacteriostasis rate on banana fusarium oxysporum reaches 74.39% +/-0.99%; the growth of fusarium oxysporum TH4 hyphae can be inhibited, the hyphae malformation and cross-linking deformation are caused, and the number of spores is gathered and increased; a pot experiment shows that the chaetomium spirotralis 201 plays a role in inhibiting infection of the TR4; moreover, the chaetomium curvilinear 201 does not generate a pathogenic effect on banana leaves and is not a potential pathogenic bacterium of bananas; the invention provides a new fungus resource for prevention and treatment of banana fusarium wilt in the later period. 本发明提供了一种螺卷毛壳菌201及其应用，属于生物防治技
