Trichoderma spp. are fungi that are present in substantial numbers in nearly all agricultural soils. They received attention mainly due to their importance in biological control of soil-borne plant pathogens. They are used in reasonably large quantities in plant agriculture both for disease control and increased yield.Tri Pun2 followed Tri Pun inhibited maximum mean growth of soil borne plant pathogens during dual culture methods. On the basis of microscopic observation and growth characteristics native Tri-Pun and Tri-Pun2 isolates were tentatively identified as T. virens and T. harzianum, respectively. Though the competitive saprophytic ability (CSA) of Thdl was best as compared to native isolates, Tri Pun and Tri Pun2 also belong to higher CSA group. Tri Pun and Tri Pun2 were compatible with chlorpyriphos upto 500 ppm concentration and 50% inhibition in growth was observed beyond 500 ppm concentration. Tri Pun2 was comparatively less sensitive than Tri Pun against chlorpyriphos. Both Tri Pun and Tri Pun2 were compatible with mancozeb. Tri-Pun2 was found to be the most effective after Bavistin for management of web blight disease of mungbean. The efficacy of native Trichoderma isolate in reducing web blight infection of mungbean was statistically at par with application of carbendazim @ 0.1 %, thus reducing our dependency on chemical pesticides to some extent and consequent hazards to our ecosystem, which need further exploration.
