Abstract: Black scurf (Rhizoctonia solani) diseases of potato are becoming prominent in many potatoes growing state resulting in economic losses, since a decade. An experiment was conducted to find out more effective management approaches through chemicals, taking cv. Kufri Bahar with five treatments involving chemicals i. e. Penflufen 240 F S and Boric acid, application before planting. Based on 2 years pooled data revealed that all the treatments were significant over control in terms of yield. Maximum total tuber yield was obtained from treatment T-3(27.69t/h) and minimum (24.03t/h) was in treatment T-1(Control). However, minimum percent incidence of disease and disease severity at harvest was observed in treatment T-3(Tuber dip treatment with Penflufen (0.083 %) for 10 min. before planting) followed by treatment T-2 (Tuber dip treatment with Penflufen (0.062 %) for 10 min. before planting)
