Objectives:  1. Management of GTD in nurseries and young vineyards a) investigate non-destructive methods and evaluate molecular tools to efficiently detect Grapevine Trunk Diseases (GTD) pathogens in nursery material; b) evaluate the status of domestic and imported nursery material with regard of GTD; c) determine abiotic stress factors favoring GTD development in newly established vineyards. 2. Management of GTD in mature vineyards. a) investigate and implement novel and existing chemicals and/or biological control agents against GTD; b) investigate and implement best cultural practices to mitigate GTD under BC growing conditions
