Antagnism of three strains of Trichoderma spp. against mycelial growth of Rhizoctonia salani
Three strains of Trichoderma spp. TV112, TX003, TY009 obtained from previous experiments could inhibit the sclerotial formation of two strains of Rhizoctonia salani AG1(-1A) isolated from the rice paddies in Hanzhou of China. However, it is unclear if there are the antagonism and mycoparasitism of t...

| description | Three strains of Trichoderma spp. TV112, TX003, TY009 obtained from previous experiments could inhibit the sclerotial formation of two strains of Rhizoctonia salani AG1(-1A) isolated from the rice paddies in Hanzhou of China. However, it is unclear if there are the antagonism and mycoparasitism of the Trichoderma strains tested against the mycelial growth of R. solani. The objective of this research was to evaluate the ability of the Trichoderma strains to inhibit the mycelial growth of R. solani in vitro.Dual culture testes showed all the Trichoderma strains tested inhibited the mycelial growth of R. solani. The strains also produced toxic metabolites with activity against R. solani, inhibiting the mycelial growth by 74%, 81.8%, and 53%, repectively. Electron microscopic observations revealed that all the Trichoderma strains interacted with R. solani. The strains TV112 and TX003 grew toward and coiled tightly around the host cells, penetrating and destroying the hyphae. TX009 penetrated the cell wall of R. solani by antagonist directly without formation of appressorium-like structure. Penetration of the Trichoderma strains on host cells was apparently accomplished by mechanical activity. These results demonstrated that all the three strains were effective in inhibiting the mycelial growth of R. solani. |
