Abstract

Data over two seasons indicated that Azoxystrobin 25 SC at the rate of 125 g a.i. ha−1 (or 500 mL ha−1) dose controlled powdery mildew (85.5%) and downy mildew diseases (83.62%) of grapes. This dose was at par with higher dose and resulted better yield than other fungicides such as Hexaconazole 2% SC and Cymoxanil 8% + Mancozeb 64%. Azoxystrobin 25 SC at 250 g a.i. ha−1 did not cause any phytotoxic symptom in grapevine
