Abstract

Downy mildew is destructive and yield limiting disease in grapes incited by a biotrophic fungi Plasmopara viticola. Owing to aggressive virulence in pathogen the development of resistance against the fungicides is early. To cater this need, efforts were made to evaluate newer fungicides against grape downy mildew during two seasons (rabi/summer 2021-22 and 2022-23), at college of Horticulture, Bagalkot, Karnataka. Of the different treatments in both seasons the combi fungitoxicant, mandipropamid and zoxamide revealed lowest disease index (DI) of 13.02 per cent and 12.70 per cent with higher grape yield of 18.07 t/ha and 19.05 t/ha, respectively. Thus, this combi fungicide may be included in integrated downy mildew management schedule in grape cultivation.
