Grape (Vitis vinifera) is a commercially important fruit crop of India. Downy mildew (c.o. Plasmopara viticola) is a devastating fungal disease of grapes causing 60-70% of crop loss thereby altering the grape economy significantly. Mancozeb, an ethylene-bis-dithiocarbamate fungicide is extensively used to control a wide variety of plant diseases. Due to its multisite mode of action, mancozeb has not developed resistance to fungal diseases. Azoxystrobin, a systemic, broad-spectrum, Quinone outside Inhibitor fungicide exerts its fungicidal activity by inhibiting mitochondrial respiration in fungi. The combination of fungicide i.e. Mancozeb 40% + Azoxystrobin 7% OS was evaluated for two seasons under field conditions at Maharashtra. Different concentrations of Mancozeb 40% + Azoxystrobin 7% OS at viz. 1250, 1500 and 1750 g/ha were compared with its component fungicides Azoxystrobin 23%SC and Mancozeb 75% separately. Pooled data revealed that Mancozeb 40% + Azoxystrobin 7% OS @ 1750g/ha manifested lowest PDI of 21.94 with a corresponding yield of 24.9 t/ha. As Mancozeb 40% + Azoxystrobin 7% OS @1750 also was at par with dose of @1500g/ha, hence the fungicide@1500- 1750 g/ha may be recommended for the control of downy mildew of grapes. The test fungicide was not phytotoxic to the grapevines. Not Available |
