The powdery mildew disease of Babchi (Psoralea corylifolia) caused by Erysiphe cichoracearum is a devastating disease results into complete defoliation of leaves due to severe infection, which hampers seed yield. Babchi a medicinal plant whose seeds are used in the treatment of leprosy, leucoderma, psoriasi and other skin diseases. Seed oil is recommended for application over scalps to treat dandruff. The plant extracts have been reported to posses antibacterial, antitumor, antioxidant, anti-inflammatory properties. Such a wonderful crop suffered from powdery mildew. Looking to the importance of this disease the field experiment was conducted during kharif 2017-18 for its management. The experiment was conducted with seven treatments which were replicated thrice in a randomized block design. The treatments were T1- Spraying of salicylic acid @ 100 ppm, T2- Spraying of butter milk @ 5 ml/litre, T3- Spraying of mineral @ 10 ml/litre, T4- Spraying of yeast Ampelomyces quisqualis @ 5 g/litre, T5- Spraying of Baking soda @ 2 g/litre, T6- Spraying of wetable sulphur @ 2.5 g/litre and T7- Untreated control. The sprayings were undertaken as soon as the powdery mildew disease was noticed on few plants, overall three sprays were taken at an interval of 15 days. The results indicated that all the treatments significantly recorded lowest powdery mildew intensity and maximum seed yield as compared to untreated control. The lowest powdery mildew intensity 29.68% was observed in treatment T6 i.e. spraying of wetable sulphur with maximum reduction 60.33% of powdery mildew and highest seed yield 17.75 q/ha. However, the treatment T4 i.e. spraying Ampelomyces was statistically on par with the treatment of wetable sulphur for both the characters i.e. powdery mildew intensity (23.63%) and seed yield (17.36 q/ha). The results obtained from present investigation concluded that three sprayings of wetable sulphur @ 2.5g/lit. or yeast i.e. Ampelomyces quisqualis @ 5 g/lit. was found to most effective for the management of powdery mildew of Babchi crop.
