Abstract
Sage (Salvia officinalis Linn.) is an important aromatic and medicinal plant. The root rot caused by Fusarium solani and Rhizoctonia solani is a serious malady in it's cultivation. There was cent per cent disease incidence with six per cent and above soil inoculum level to cause infection in case of F. solani on sage. Whereas Rhizoctonia required higher inoculum level (8 to 10 %) and took more time to cause infection and 100 per cent root rot incidence was noticed at eight per cent and above inoculum levels. The seedlings are more susceptible at the age of 30 - 60 days. The Fusarium solani is found to be more virulent as compared to R. solani in causing quick root rot symptoms.
