This article is focused on the fact that when dispersing the pesticide in vineyards with a fan sprayer for pest and disease control, any loss of about 30-90% of the working fluid caused by drift, evaporation, settling on the ground, etc. has a negative impact on the environment, health and economy. Therefore, the challenge of minimizing the loss of pesticides is not only a problem of environmental character, but also of a sociological one. This paper presents some results of accomplished investigations proving that the sprayer working fluid recovery sufficiently reduces the specific quantity of pesticide losses.
