Brinjal is one of the important vegetable crop cultivated widely in India. It is susceptible to many diseases like sclerotium rot/wilt, verticillium wilt, fusarium wilt and bacterial wilt and it is being attacked by several diseases of fungi and bacteria. The collar rot/wilt disease caused by Sclerotium rolfsii is an important constraint in brinjal production. Hence, an in vivo study was conducted to evaluate the bio efficacy of antagonistic bioagents and fungicide chemicals against root rot/wilt disease of Brinjal at College of Agriculture, Bheemrayangudi during 2011–2012.
