Abstract: A field experiment was conducted during the year 2016-17 on farmer’s field of village Barad, Tq. Mudkhed, District-Nanded in randomized block design, replicated three times with eight treatments of fungicides spray viz., T1-single spray of Dithane M-45 75 WP @0.25%, T2- single spray of Azoxystrobin 25 EC @0.06%, T3-Spraying of Dithane M-45 @0.25% alternated with spraying of Azoxystrobin @0.06% (C→S two sprays at 15 days interval), T4- Spraying of Dithane M- 45 @0.25% alternated with spraying of Azoxystrobin @0.06% (C→S→C three sprays at 15 days interval), T5- Spraying of Dithane M-45 @0.25% alternated with spraying of Azoxystrobin @0.06% (C→S→C→S four sprays at 15 days interval), T6- Spraying of Dithane M- 45 @0.25% alternated with spraying of Azoxystrobin @0.06% (C→S→C→S→C five sprays at 15 days interval), T7- Spraying of Dithane M-45 @0.25% alternated with spraying of Azoxystrobin @0.06% (C→S→C→S→C→S six sprays at 15 days interval), T8- Control, were used to optimize the spray schedule of these fungicides on the intensity of sigatoka leaf spot disease and yield contributing characters of banana. Lastly, it can be concluded that treatment T6 i.e. spraying of Dithane M-45 @0.25% alternated with spraying of Azoxystrobin @0.06% (C→S→C→S→C five sprays at 15 days interval) and treatment T7- Spraying of Dithane M-45 @0.25% alternated with spraying of Azoxystrobin @0.06% (C→S→C→S→C→S six sprays at 15 days interval), recorded significantly minimum percent disease index of sigatoka leaf spot (19.85% and 20.12% respectively) and obtained maximum yield of banana in treatment T7 (91.26 Mt/ha).
