Next generation varieties resistant to diseases: new opportunities for wine-growers

FLEURTAI-GRAPPOLOMost grape varieties cultivated are affected by pathologies caused by fungi, viruses, phytoplasmas and insects towards which the plants don’t have defences; therefore they require, for their protection, a massive use of pesticides, especially in temperate areas with high rainfall and humidity. Despite today’s phytosanitarian control is conducted with active substances certainly more environmentally sustainable, viticulture remains the agricultural activity more polluting.
In this context, the reduced use of fungicides and environmental resources are considered priorities in the wine sphere. Currently the most important Research Centres who deal with genetic improvement (I.G.A – Udine, the Institute of Freiburg, University of Novi Sad) are very active in the creation and selection of new disease-resistant varieties, just to meet the demand of agricultural products more healthy and with less impact on the environment.
The University of Udine in Italy since 1998 has undertaken an extensive program of crossing and selection of vines resistant to diseases of new generation, which led to the inscription to the National Catalogue of Grape Varieties 10 new resistant varieties: 5 with white berry and 5 with red berry, marketed by Vivai Cooperativi Rauscedo.
The use of these new varieties resistant will allows to reduce the use of pesticides and to achieve a significant energy and cost savings, improving consistently the environmental impact and ensuring productions more healthy for the final consumer. Photo: Fleurtai (UD. 34.111) bunch.
