Efficacy of fungicides and bioagents against powdery mildew of Okra

Five fungicides, two bioagents were evaluated in field condition against Erysiphe cichoracearum causing powdery mildew of okra. Fungicide wettable sulphur 80 WP (0.25%) was found to be the most effective in reducing disease severity (9.23 PDI) after third sprays followed by triadimefon (10.36 PDI). carbendazim (11.46 PDI) and propiconazole (15.56 PDI). Maximum disease control after second and third spraying was recorded in fungicide wettable sulphur (0.25%) followed by triadimefon and carbendazim. Bioagents like Pseudomonas fluorescens and Trichoderma viride were recorded 43.05 and 44.30 per cent disease control (PDC) respectively over. control. Maximum fruit yield (11.25 t/ha) was observed in wettable sulphur (0.25%) spray.
