[Objective] The aim was to study effect of Chaetomium globosum ND35 on plant growth and preliminary study of its biocontrol efficacy, and provide basis for popularization and application of this strain.[Method] With endophytic fungus C.globosum ND35 as a tested strain, effect of C.globosum ND35 on plant growth and its biocontrol on five plant diseases were investigated in the greenhouse and field.[Result] The results showed that ND35 promoted growth of lateral root and diameter of breast height of poplar.ND35 can induce poplar to resist poplar canker caused by Valsa sordida and poplar leaf rust caused by Melampsora puplicola.ND35 was also able to induce tomato and bean to resist Botrytis cinera.Biocontrol of bean damping-off by ND35 was effective as well.[Conclusion] Induced systemic resistance by endophytic C.globosum ND35 plays an important role in biocontrol of plant diseases.
