Ridge gourd (Luffa acutangula L.) is a pantropical climbing herb belongs to cucurbitaceae. It is affected by fruit rot disease caused by Sclerotium rolfsii Sacc. The present investigation exhibits the sensitivity of Sclerotium rolfsii Sacc. against different concentration of propiconazole. There was quite a large variation in MIC (Minimum Inhibitory Concentration) of propiconazole among the 14 isolates of S. rolfsii collected and isolated from different districts of Maharashtra and Karnataka. MIC on agar plate (In vitro) was ranged from 40 μl/ml to 60 μl/ml, while on fruit (In vivo) ranged from 24 μl/ml to 35 μl/ml. The MIC result showed that, isolate Sr-6 was sensitive from Sangola (Solapur) and Sr-11 was resistant from Waddwadi (Kolhapur).
