Mutagenesis of Trichoderma asperellum through chemical and physical means and tolerance of T. asperellum mutants to commonly used fungicides was carried out at Department of Plant Pathology, Dr. PDKV, Akola. The treatments with chlorothalonil 50 per cent WP @ 0.25 per cent, carbendazim 50 per cent WP @ 0.1 per cent, propiconazole 25 per cent EC @ 0.1 per cent, thiophanate methyl 70 per cent WP @ 0.25 per cent and carboxin 37.5 per cent + thiram 37.5 per cent @ 0.25 per cent, recorded complete growth inhibition of mutants and mother culture of T. asperellum. Mycelial growth of mutants and mother culture in the range of 20 to 85 mm was recorded in azoxystrobin 23 per cent SC @ 0.1 per cent. It proved that fungicide azoxystrobin 23 per cent SC @ 0.1 per cent concentration was more compatible with T. asperellum mutants and mother culture. Among the mutants, TaU4(T12) was recorded 84.4 mm mycelial growth with azoxystrobin 23 per cent SC @ 0.1 per cent at 7 DAI, where as TaU1(T11), TaG2(T14), TaU2(T10) and TaG1(T13) recorded 80.5, 79.9, 75.8 and 75.00 mm growth respectively. The mother culture TaMc (T17) recorded 29.1 mm growth.
