Abstract

Collar rot disease is one of the major disease of brinjal caused by Sclerotium rolfsii Sacc. The experiment on the management of collar rot disease of brinjal was conducted during kharif 2018 at Department of Plant Pathology, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). Management of collar rot disease were carried out by bioagents, botanical extracts and fungicides. The in-vitro evaluation revealed highest average mycelial growth inhibition with fungicides, Tebuconazole (94.38%), Mancozeb 75% WP (77.52%) and Carbendazim 50% WP (65.19%). Among bioagents highest inhibition percent was recorded with Pseudomonas fluorescens isolate 12(64.97%) and Trichoderma harzianum (34.02%). Among the botanical extracts 100% inhibition against pathogen was recorded with garlic extract.
