Abstract:
Early blight is serious as well as destructive disease of the tomato crop responsible for the low production and productivity. As it is air as well as seed born pathogen it is difficult to manage by using only chemical fungicides. Hence a study was undertaken to determining the efficacy of seven biocontrol agents for management of early blight of tomato caused by Alternaria solani in in vitro. The biocontrol agent T. harzianum showed highest mycelial growth inhibition (75.2%). Next best were T. asperellum, M. anisopliae, T. virens. The least percent inhibition of pathogen was observed in treatment of V. lacani.
