Powdery mildew (Erysiphe cichoracearum) of cucurbits is an important disease causing heavy losses to vegetable growers. Among the four fungicides tested for effective control of the disease, four sprays of Amistar 25 SC @ 0.1 per cent at seven days interval from initial onset of infection was found most effective. This treatment was followed by four sprays of Carbendazim 50 WP @ 0.1 per cent, followed by Amistar 25 SC @ 0.08 per cent and Penconazole (Topaz) 10 EC @ 0.05 per cent.
