Abstract

The invention concerns a method for adjusting a field sprayer (10), which consists in controlling, according to treatment parameters, the flow rate of a treating product, sprayed by a set of nozzles (1), characterised in that it consists in dimensioning the discharge orifice (1c) of the nozzles (1c) to obtain a given aperture or closure of said discharge orifice (1c) on the basis of values related to data derived from sensors and set-points.
