Abstract:
The genus Trichoderma belongs to ascomycetic fungi that are present in nearly all soils and other diverse habitats. In soils they frequently are the most prevalent culturable fungi. These fungi have been widely studied for their biocontrol activities viz., micoparasitism, antibiosis, competition for nutrient and space, niche exclusion, stress tolerance, induced resistance in plants as well as inactivation of the pathogen’s enzymes by producing various antimicrobial compounds thus it reduces the pathogen populations, enhances the vegetative growth and protect the plants under numerous agricultural conditions. Hence in the present study was conducted to assess the biocontrol activities of Trichoderma spp. viz., T. asperillum, T. virens and T. aureoviridae was carried out against most important soil borne plant pathogens like Pythium myriotylum causing ginger rhizome rot and Pythium aphanidermatum causing damping off in tomato using dual plate method, invert plate technique and culture filtrate technique method. Among three species of Trichoderma, T. virens showed 71.62 and 71.23 percent inhibition of Pythium myriotylum and Pythium aphanidermatum followed by T. asperillum (55.13 and 60.86%) and T. aureoviridae (50.65 and 57.16%) respectively in dual plate technique. Moderate inhibition was observed in culture filtrate technique (51.42 & 45.25%) and least inhibition was observed in invert plate technique (43.49 & 29.11%).
