Botryosphaeriaceae species affecting table grape vineyards in Chile and cultivar susceptibility

Several Botryosphaeriaceae species have been identified as the causes of cankers and dieback of Vitis vinifera in several grape-growing regions around the world. This research was conducted to further study the species of Botryosphaeriaceae associated with table grapes in Chile, to estimate the prev...

This research was conducted to further study the species of Botryosphaeriaceae associated with table grapes in Chile, to estimate the prevalence and severity of the disease as a function of vineyard age, to study the susceptibility of table grape cultivars to infection by Botryosphaeriaceae species, and to evaluate the effect of tissue age on the infection caused by Botryosphaeriaceae species. Symptoms were characterized by the presence of the partial or total death of the grapevine cordons and distorted leaves. Brown V-shaped or U-shaped cankers and black spots were observed in cross-sections, while brown vascular streaks were observed in longitudinal sections of the cordons and trunks. Pathogenic isolates of Diplodia seriata, D. mutila and Spencermartinsia viticola were consistently obtained from wood cankers and/or vascular streaking; D. seriata was the most common (83.3%) Botryosphaeriaceae species. In 11- to 20-year-old vineyards, the disease incidence varied between 22.0 and 69.0%, and the severity varied between 6.0 and 21.3%. The table grape cultivars 'Thompson Seedless', 'Redglobe' and 'Flame Seedless' were equally susceptible to infection by D. mutila, D. seriata and S. vitícola. The age of the inoculated tissue had no significant effect on the development of the vascular necrosis.
