ND35 can induce poplar to resist Poplar Valsa Canker caused by Valsa sordida and Poplar Rust caused by Melampsora puplicola. ND35 was also able to induce tomato and bean to resist Botrytis cinera. Biocontrol of Bean Stem Rot Rhizoctonia by ND35 was effective as well. [Conclusion] Induced systemic resistance by endophytic C. globosum ND35 plays an important role in biocontrol of plant diseases.展开更多
