Researches regarding the reduction of pesticide soil pollution in vineyards

For the vegetation phase V and for the forward speeds and operating pressures taken into account the quality of the treatment was evaluated using the mean foliar deposit. The results obtained by the means of ImageJ processing software indicated an adequate operating process of the spraying equipment; the values of this index were ranged between 21.4% and 36.2% for the upper side of the leaves and between 18.6% and 29.7% for the lower side of the leaves. The best indices were attained for low forward speed and an operating pressure of 0.6 MPa.
