Abstract
Bean anthracnose caused by Colletotrichum lindemuthianum is a serious seed borne disease. For devising an effective management strategy, the efficacy of different bioagents, viz. Trichoderma viride, Trichoderma harzianum, Trichoderma hamatum and Gliocladium virens conducted under in vitro and in vivo conditions revealed maximum inhibition of mycelial growth in dual culture (59.48%) and inverted plate (55.98%) with T. viride. All the bioagents overgrew the pathogen and the principal mechanism of mycoparisitism observed was coiling, brusting and disintegration of pathogen hyphae. Culture filtrate from T. viride was found best as it completely inhibited radial growth at 25 and 50% concentration and reduced the spore germination of test fungus significantly. However, lower concentrations of culture filtrate from all bioagents showed little effect on spore germination. Seed application of bioagents was found better as compared to soil application. A maximum increase in seed germination and inhibition of seed borne infection was observed with T. viride followed by T. harzianum under pot culture conditions. T. viride has the maximum potentiality to suppress the spore germination, mycelial growth, seed borne infection of C. lindemuthianum and increased seed germination when compared with the other biocontrol agents.
