| Abstract | ||
| The present study was conducted in 2015 and 2016 to find out the best ecofriendly method(s) to control downy mildew disease of grapes. Water extracts of castor, oleander and mint significantly reduced the disease incidence, increased chlorophyll and carotenoids content, improved plant water relations and increased yield production. The same observations were obtained using emulsion oils of castor, thyme and mint. Castor water extract and emulsion oils showed the best results, all treatment of plant oils and plant extracts caused a significant remarkable increase in no. of clusters, cluster length and yield per plant | ||
