BIOLOGICAL CONTROL OF WILT OF EGGPLANT CAUSED BY FUSARIUM SOLANI F. SP. MELONGENAE (Pages : 20 - 25)

An in vitro study was carried out to determine the potential of four selected isolates of Trichoderma; namely, Trichoderma harzianum, T. koningii, T. viride (green strain) and T. viride (yellow strain) against soil borne phytopathogenic fungi Fusarium solani f. sp. melongenae. All Trichoderma isolates showed inhibitory effect on mycelial growth of the pathogen in dual culture. The maximum inhibition was recorded in F. solani f. sp. melongenae- T. viride interactions. The pathogen was most susceptible to the volatile inhibitors produced by T. koningii and T. viride (yellow strain). Naturally untreated metabolites from T. viride (green strain) were found to be the most effective one. The fungicides Bavistin50 WP was found more effective than Dithane-M45. In pot culture experiment, the efficacy of Trichoderma spp. were measured by the growth parameters such as plant height, leaf number, internodal distance, branching number, leaf breadth, stem diameter at seedling stage in both solarized and non-solarized soil. Re-isolation of Trichoderma was also conducted from the experimental root samples. Download
