Downy mildew caused by Pseudoperonospora cubensis is one of the most widely spread and economically important disease of cucumber. The present investigation was carried out to evaluate the efficacy of different fungicides and biocontrol agents for the management of the disease. Soil application of Trichoderma harzianum through farm yard manure (enrichment – 1kg / 100kg for 15days), seed treatment with Metalaxyl (2.0g/kg seeds). Prophylactic spray – Mancozeb (2.5 g/L) – 3 weeks after planting followed by sprays of Metalaxyl + Mancozeb (2.5 g/L) and Dimethomorph (1.0 g/L)+ Mancozeb (2.0 g/L) based on disease severity at 5th and 7th weeks after planting depending on the disease severity was found very effective in managing the disease.
