In the paper the authors made a presentation of a nozzle that can endow the machines and equipment for combating diseases and pests, as well as chemical control of weeds by spraying. After describing the communications in which these treatments are performed, conditions presented in the literature, the authors refer in particular to the phenomenon of droplet drift when the speed of displacement of the aggregate exceeds certain limits or when the velocity of the air current increases accidentally during the treatment. Derivatives to spills may lead to phytotoxicity phenomena or the destruction of other cultures that do not support the active substance in the solution. It has thus determined the velocity of the air currents and dynamic wind pressure, moment and torsional force at which is subjected to the nozzle arc and the magnitude of the derivation and the random dispersion of the droplets, was the way the nozzle can be used.
