(FR) SYSTEME DE PULVERISATION A DOSAGE ADAPTE
Abstract:
(EN) A method and a device for the dosage of plant protection agent for delivery to a cultivation area using a spray device consisting of at least two tanks (1, 2) having lines which connect the tanks (1, 2) with a mixing chamber and a spray device having nozzles, such that the contents of one tank (1) may be mixed with the contents in the other tank (2), characterized in that one tank (1) contains a plant protection agent in a maximally permissible concentration and the other tank (2) contains a diluent, preferably water.
(FR) Cette invention concerne un procédé et un dispositif permettant le dosage d'un agent de protection des plantes avec lequel on souhaite traiter une zone de culture. Ledit procédé consiste à utiliser un dispositif de pulvérisation constitué d'une part d'au moins deux réservoirs (1, 2) reliés au moyen de conduits à une chambre de mélange et d'autre part à des diffuseurs, le contenu de l'un des réservoirs (1) pouvant être mélangé au contenu de l'autre réservoir (2). Le dispositif de l'invention se caractérise en ce que le réservoir (1) contient un agent de protection des plantes en concentration maximale admissible et l'autre réservoir (2) contient un diluant qui est, de préférence, de l'eau.
