Abstract
In the Arava, there is little use of pesticides for the control of pests and diseases. This fact makes it possible to evaluate the organic production of table grapes. Together with the increasing public awareness of the issue of pesticide residues, the Yair Research Station was allocated an organic vineyard. In 2007, there was a severe outbreak of powdery mildew in this vineyard and none of the produce from that year could be marketed. In 2008-2009, we tested a treatment program for the control of powdery mildew that was appropriate for an organic vineyard. This program was based on a preliminary treatment following pruning to ensure early and uniform emergence from dormancy, as well as the use of polyethylene sheets on the rows of the vineyard. The pruned vines in the plots that had been covered with polyethylene sheets emerged from dormancy earlier and in a more uniform fashion than the vines in the uncovered plots. The grape yield was relatively high as compared to that observed in a conventional vineyard of cv. SBS (‘Early Sweet’), approximately 3 tons/dunam of high quality grapes and an additional 0.75 tons/dunam of lower quality grapes. Research efforts toward a preventative treatment for powdery mildew should be continued.
