Grapevine trunk diseases (GTDs) of mature vines (Botryosphaeria and Eutypa diebacks and Esca) largely contribute to the grapevine decline in all viticultural regions of Europe. Different biotic and abiotic factors may explain this situation. Among them, cultural practices may increase or decrease the incidence of GTDs. Under the framework of the COST action FA1303 'Sustainable control of grapevine trunk diseases', an anonymous questionnaire was designed and sent to growers representing the most important viticultural regions in Europe (plus Israel). The objective of this survey was to know more about the current interest for prophylactic measures, including cultural practices, recently or traditionally recommended within a control strategy towards GTDs. Questions were divided in four categories: general questions to know whether growers applied cultural practices to control GTDs or not, questions to know more about the practices used to remove or reduce inoculum sources, to prevent GTDs, or fially to control infection. Results indicated that growers generally have a better knowledge on the application of remedial strategies for disease control, than on preventative practices that can be used for the control of GTDs. A small number of growers are aware of pruning systems that can have the potential to reduce GTDs, such as the Guyot Poussard pruning system. Therefore, a major effort seems necessary to increase the knowledge and training on the principles and methods to prevent and to reduce infection by GTDs in mature vineyards.

Abstract
Grapevine trunk diseases (GTDs) of mature vines (Botryosphaeria and Eutypa diebacks and Esca) largely contribute to the grapevine decline in all viticultural regions of Europe. Different biotic and abiotic factors may explain this situation. Among them, cultural practices may increase or decrease the incidence of GTDs. Under the framework of the COST action FA1303 'Sustainable control of grapevine trunk diseases', an anonymous questionnaire was designed and sent to growers representing the most important viticultural regions in Europe (plus Israel). The objective of this survey was to know more about the current interest for prophylactic measures, including cultural practices, recently or traditionally recommended within a control strategy towards GTDs. Questions were divided in four categories: general questions to know whether growers applied cultural practices to control GTDs or not, questions to know more about the practices used to remove or reduce inoculum sources, to prevent GTDs, or fially to control infection. Results indicated that growers generally have a better knowledge on the application of remedial strategies for disease control, than on preventative practices that can be used for the control of GTDs. A small number of growers are aware of pruning systems that can have the potential to reduce GTDs, such as the Guyot Poussard pruning system. Therefore, a major effort seems necessary to increase the knowledge and training on the principles and methods to prevent and to reduce infection by GTDs in mature vineyards.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
