Management of Powdery Mildew of Okra Caused by Erysipheci choracearum

Percent disease intensity of powdery mildew of okra revealed significant differences due to fungicides spray over water and control after spraying. The maximum percent disease control were recorded with hexaconazole (87.33%) followed by propiconazole (86.08%).Average yield q ha-1 of okra were significantly, influenced due to different treatments over control treatment. Significantly higher yield of okra obtained with 0.1 percent hexaconazole 54.29 q ha-1 and 0.1 percent propiconazole 48.48 q ha-1 were at par with each other and significantly superior over rest of treatments.The highest Incremental cost benefit ratio was recorded by 0.1 percent hexaconazole 1:13.72 followed by fungicides 0.3 percent wettable sulphur 1:5.62 and 0.1percentpropiconazole 1:4.84. From present investigation, it is concluded that three sprays of hexaconazole @ 0.1 percent minimize the intensity 10.78 percent of disease and achieve yield 54.29 q ha-1 with best ICBR 1: 13.72 can be use for management of powdery mildew of okra.
