Abstract

La présente invention concerne un procédé pour épandre un produit à pulvériser (36), en particulier un produit phytosanitaire (36), sur une surface agricole (38) à traiter au moyen d'un dispositif de pulvérisation (14) présentant un réservoir (18) pour produit à pulvériser et au moins une conduite de raccordement fluidique (24) allant du réservoir (18) pour produit à pulvériser jusqu'à une buse (20). Le procédé présente les étapes suivantes, à savoir : - l'épandage sélectif du produit à pulvériser (36) sur une parcelle de début de la surface agricole et ensuite - l'épandage en surface d'une quantité résiduelle de produit à pulvériser (36) sur une parcelle résiduelle de la surface agricole avec une quantité d'épandage prédéfinie, de telle sorte qu'à la fin du traitement de la surface agricole, la totalité de la quantité résiduelle de produit à pulvériser (36) soit sensiblement épandue.
