Sclerotium rolfsii is a destructive soil-borne pathogen causes over 500 spp. in 100 families of agricultural and horticultural crops. Collar rot disease of chickpea caused by pathogen Sclerotium rolfsii Sacc. First symptom associated with S. rolfsii are usually girdling or rotting at basal or collar region of the stem resulting yellowing and wilting of entire plant. In the current study, the seven microorganisms were evaluated by dual culture technique for their antagonistic effect against S. rolfsii under In-vitro conditions. Maximum mycelial growth inhibition (80.97%) was noticed in Trichoderma harzianum which was followed by Pseudomonas fluorescens (74.04%). Least inhibition was observed in T. virens (45.53%). The results showed that the application of these bioagents were successfully decreases the disease incidence in chickpea.
