Online published on 10 September, 2024. Abstract Downy mildew (Pseudoperonospora cubensis) is an important disease capable of causing heavy losses to cucumber in a short time and as a result judicious and timely application of fungicides remains one of the most important strategies for management of this disease. The present study was undertaken during two seasons of year 2019 and 2021 under field conditions to assess the efficacy of iprovalicarb 8.4% + copper oxychloride 40.6% WG (750 g, 1000 g and 1250 g/ ha) in comparison with copper oxychloride 50% WP @ 1015 g/ha and cymoxanil 8% + mancozeb 64% WP @ 1500 g/ ha against downy mildew of cucumber. Results from two years experiment indicated that three foliar applications of iprovalicarb 8.4% + copper oxychloride 40.6% WG @ 1000 g/ha at 7 days intervals were highly effective when applied as soon as the first symptoms of the downy mildew appear. The treatment iprovalicarb 8.4% + copper oxychloride 40.6% WG @ 1000 g/ha provided 74.52 and 80.69 per cent disease control during 2019 and 2021, respectively.
