The efficacy of spraying programmes and treatment methods against downy mildew in two grapevine cultivars in Kosovo
Archives of Phytopathology and Plant Protection 47 (4), 407-416
Abstract: The present study aimed to assess the efficacy of applied programmes and treatment methods against downy mildew (Plasmopara viticola). Two vine cultivars (Frankovka and Game) were tested in an experimental field (in Rahovec, Kosovo) for a two-year period (2010-2011). The fungicides used were Quadris (azoxystrobin), Antracol EP-70 (propineb), Dithan M-45 (mancozeb), Ridomil (metalaxyl), Curzate (cymoxanil), Bordeaux mixture (calcium hydroxide and copper sulphate) and Mikal (fosetyl-aluminium) applied three treatment methods. The evaluation of the disease severity was performed using the McKinney index. In both tested cultivars and in both treatment years (2010 and 2011), all of the programmes tested significantly reduced the severity of grape downy mildew compared to the control. The highest efficacy against grape downy mildew was achieved with the combined use of Ridomil and Dithan (programme 3); this treatment was more than 80% effective in both cultivars and in both years.
