Abstract:
The current investigation was carried out during 2020-21 where in twenty-seven isolates of Trichoderma were obtained on TSM from sixty seven soil samples collected from various places in Konkan region of Maharashtra. All the isolates were found effective against the five test pathogens Fusarium spp., Rhizoctonia spp., Sclerotium spp., Colletotrichum spp. and Alternaria spp. when tested by dual culture technique. Among them seven isolates viz., the isolates 11, 3, 23, 5, 14, 25 and 24 showed better inhibition.11 was the most effective against Fusarium spp.(82.22% inhibition), 14 against Rhizoctonia spp.(81.11%), 23 against Sclerotium spp.(86.11%), 5 against Colletotrichum spp.(81.33%), 25 against Alternaria spp.(86.66%). In terms of fungicide compatibility, all the seven isolates were extremely sensitive to Carbendazim and five isolates were fairly compatible with Sulphur.
