  In vitro potentialities of seven species of Trichoderma were evaluated against phytopathogen Macrophomina phaseolina by dual culture techniques. The maximum growth inhibition of test pathogen was observed by antagonist T. koningi MTCC 796 (T4) (74.3%) followed by T. harzianum NABII Th 1 (T1) (61.4%) at 7 days after inoculation (DAI). Further, mycoparasitism of antagonists were observed upto 14 DAI. Pattern of growth inhibition of test fungus was continued with maximum 14.7% increases in T4 (85.2%) followed by 6.8% elevation in T1 (65.6%) antagonists during 7 to 14 DAI. Microscopic study showed that these two antagonists were capable of overgrowing and degrading M. phaseolina mycelia, coiling around the hyphae with apressoria and hook-like structures. At 14 DAI, T. koningi MTCC 796 completely destroyed the host and sporulated. The specific activities of cell wall degrading enzymes- chi.. View More»
