Occurrence of fungal pathogens associated with grapevine nurseries and the decline of young vines in Spain
Journal of Phytopathology 154 (10), 598-602
Abstract: The occurrence of fungal grapevine trunk pathogens associated with grapevine nurseries and the decline of young vines in Spain was determined in extensive surveys conducted in nurseries and vineyards with young plants. The presence of Phaeomoniella chlamydospora, Phaeoacremonium aleophilum, Cylindrocarpon spp., Botryosphaeria obtusa and Botryosphaeria spp. was detected in all the surveys that were carried out. This study provides evidence for the presence of these pathogens in Spanish grapevine nurseries. Cylindrocarpon spp., B. obtusa and Botryosphaeria spp., were isolated very early in the planting material production process, nevertheless, P. aleophilum and P. chlamydospora were not detected until the rootstock-scion combinations were planted in the field to develop shoots and roots during summer. The occurrence of trunk disease pathogens in symptomatic young vineyards was also high, suggesting that infected plant material might have been used. Phaeomoniella chlamydospora and P. aleophilum were the main species associated with the decline of young vines, followed by Botryosphaeria spp., Cylindrocarpon spp. and B. obtusa. This research confirmed the importance of fungal grapevine trunk pathogens associated with the decline of young vineyards in Spain and suggested the connection between the presence of these fungi in the nurseries and the disease in the fields.
