Today a very effective crop protection is necessary to improve the production of good quality wine and to limit the environmental pollution. Field tests were carried out in a Sicilian vineyard using two different sprayers, in tree periods, each corresponding to a different canopy distribution. The objective of this research was to determinate the best operative solution in order to obtain an effective vineyard protection. The quality of distribution was evaluated through the coverage index of the canopy, the number of impacts per square centimetre and the mean diameter of the drop prints on artificial targets opportunely placed into the canopy, as the canopy volume varies. The sprayers were controlled before and vertical patternators were used to determine the profile of distribution.
