Abstract
  • Pedicel necrosis is a grape disorder that is recorded in all the world's grape growing regions. Synonyms for similar disorders include stiellahme (Germany, Switzerland), dessechement de la rafle (France), palo negro (Chile), shanking (New Zealand, Britain) and waterberry (USA). Pedicel necrosis can be a serious problem. Large reductions in yield and quality have been associated with this disorder in both wine and table grape vineyards. In this brief article pedicel necrosis symptoms are described and a report is given on a survey of Oregon vineyards which showed there were very few affected clusters in 1986. Also, research on pedicel necrosis at Oregon State University is outlined.
