Intensive and reduced protection against common diseases of grapevine and its influence on bunch weight

During two years (2004, 2005) the experiments were set in a vineyard of the Polytechnics of Pozega, with the aim to examine the influence of reduced and intensive protection of grapevine against diseases. The experiment focused on two grapevine cultivars, Grasevina and Zweigelt (pruning techniques Double Guyot). Intensive protection of both experimental cultivars in both years gave better results (average weight of bunches, yield per grapevine). In 2005, disease occurrence (Plasmopara viticola and Botrytis cinerea) was very strong because environmental conditions contributed to secondary infections and negatively affected development of bunches, irrelevantly of protection system applied.
