Abstract

Sclerotium rolfsii is a soil borne plant pathogen causing root rot, stem rot, collar rot, wilt and foot rot diseases on more than 500 plant species of agricultural and horticultural crops throughout the world. SMS also possesses good bio-control activity against certain foliar and soil borne diseases and potential to bioremediate several agricultural grade fungicides and pesticides.
