The studies were carried out on collar rot caused by Sclerotium rolfsii Sacc. on betelvine (Piper betle L.) during 2015 at department of plant pathology, College of Agriculture Badnapur, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The in-vitro evaluation revealed highest average mycelial growth inhibition with systemic fungicides, carboxin and hexaconazole (100% in both), cymoxanil+ Mancozeb (92.26 %), carbendazim (90.64%) and least inhibition rate was recorded in thiophanate methyl (70.69%). While mancozeb recorded maximum growth inhibition (100%) that differed significantly with other non-systemic fungicides. Trichoderma viridae among the bio agents and Allium sativum among the botanicals significantly inhibited the myceial growth of the pathogen to the tune of 82.47 per cent and 100 per cent respectively. In the integrated management of disease study, significantly highest percentage of successful cuttings were recorded with treatment carbendazim + mancozeb + garlic extract + T. harzianum (80.17%) as compared to rest of treatments.
