A total of 50 fields comprising of approximately 59 hectare area covering 11 tehsils with 24 villages of Bikaner, Jodhpur, Sikar, Jaipur and Alwar districts of Rajasthan at preboot to flowering stage were surveyed during kharif 2016 and 2017. Out of these, ten fields of Jodhpur district showed less than 10 per cent downy mildew incidence which was 9.6 per cent of the total fields observed during survey. The average downy mildew incidence in different districts varied from 9.87 to 17.95 per cent. The maximum average downy mildew incidence of 17.95 per cent was noticed in Bikaner district followed by Sikar (17.4%), Jaipur (16.93 %), Alwar (13.35 %), and Jodhpur (9.87 %). The overall mean of downy mildew incidence of five districts was 15.1 per cent. Out of 28 cultivars grown on farmer’s fields, six cultivars were found free from downy mildew incidence. Eleven cultivars showed incidence up to 10 per cent and 11 cultivars showed more than 10 per cent incidence.
