Abstract: Cucumber (Cucumis sativus) is a widely cultivated plant in the gourd family, Cucurbitaceae. It is a creeping vine that bears cucumiform fruits that are used as vegetables. Downy mildew caused by Pseudoperonospora cubensis (Berk. and Curt.) Rostow has become a serious problem for successful cultivation of cucumber. Therefore, a field experiment was carried out on the effect of Mandipropamid 23.4 % w/w SC (Revus 25 SC) against downy mildew during 2017-18 and 2018-19, at College of Horticulture, Hiriyur. Experimental results revealed that all the treatments significantly reduced the downy mildew disease severity over untreated control. Amongst all the treatments in both season significantly least disease severity of downy mildew (5.97 and 3.66 %) was recorded with foliar application of Mandipropamid 23.4 % w/w SC (Revus 25 SC) at 1ml/lt with highest yield of 16.27 and 16.92 t/ha respectively followed by Mandipropamid 23.4 % w/w SC (Revus 25 SC) at 0.8ml/lt.
