1. A spraying apparatus for delivering liquid mixtures of phytosanitary products, the spraying apparatus equipped with a pneumatic liquid mixture atomization system which comprises:
a fan for generating a carrier airflow through a conduit of a diffuser tapering towards a reduced section;
at least one delivery nozzle for releasing said liquid mixture within said diffuser, said at least one delivery nozzle comprising a delivery end configured to be located in a first delivery position (pos.in) within said airflow at said reduced section, and in at least a second delivery position (pos.out) located downstream of said first delivery position (pos.in), external to the diffuser or at a location within the diffuser where the diffuser is wider than said reduced section, where the airflow has a lower speed compared to said first position; and
control means for alternatively selecting said first delivery position and said at least a second delivery position depending on a desired condition of reducing a drift effect on droplets of phytosanitary liquid.
