Antagonism of Trichoderma Asperellum against Rhizoctonia Solani

摘要

R. solani is a soil borne pathogens that has great harm on crops including corn, rice, wheat, cotton and a variety of fruits and vegetables. Biological control is an economic and effective method for crop prevention;;T. asperellum is a key biocontrol fungus, can growth and reproduce on the pathogen R. Solani;;moveover, also can discern and stick to the cell wall of R. solani cell wall degrading enzymes were secreted from T. asperellum to hydrolyze the hyphae of R. solani, and kill ultimately R. solani. In addition, T. asperellum can secret antifungal metabolites to inhibit and even kill directly R. solani. The study result proved that T. asperellum has highly effective in controlling R. solani.
