Abstract:

Downy mildew is a common and serious disease in cucumber (Cucumis sativus L.), caused by the obligate fungus- Pseudoperonospora cubensi. The downy mildew disease causes abundant reduction in both quality and quantity of cucumber in countries around the world. In the present study, different doses of fungicide mixtures were used to determine the most effective dose for the management of the disease under the field conditions. The Experiment was conducted during the year of 2017-18 and 2018-19 at the University farm. The use of seven fungicide mixtures against the downy mildew pathogen were applied T1-T7 with T8 as control.  The Average minimum Disease severity was found in 1st year T3 (2.221) and T2 (2.246) followed by T6 (2.982), T1 (3.709), T5 (3.773), T4 (4.499) and T7 (4.931). The average maximum disease severity was found in T8 (7.888).  Similarly, the Average minimum disease severity was found in 2nd year T3 (2.184) and T2 (2.301) followed by T6 (3.079), T1 (3.684), T5 (3.824), T4 (4.628) and T7 (5.014). The maximum disease severity average was found in T8 (8.091). Thus, our studies concluded that these fungicide mixtures were effective in lowering the disease severity under the field conditions if used with recommendations.
