Abstract:
Four Trichoderma spp. were tested for chitinase enzyme activity and antagonistic activity against soil borne plant pathogens. All the tested four isolates of Trichoderma spp. were produced the chitinase enzyme and also inhibit the growth of test soil borne plant pathogens in-vitro. However highest production of chitinase enzyme was recorded by T. asperellum (0.65/1.02) chitinase units/mg of protein followed by T. reesei (0.64/0.94), T. harzianum (0.46/0.92) and T. hamatum (0.36/0.80). All the tested Trichoderma spp. inhibited the growth of soil-borne plant pathogens invitro. Maximum% inhibition of Fusarium oxysporum f. sp. vasinfectum was recorded in T. reesei i.e (75.27%). However, maximum growth inhibition of Sclerotium rolfsii were recorded in T. asperellum i.e. (67.07%) and in Rhizoctonia bataticola (69.84%) were recorded in T. asperellum.
