ABSTRACT:
This invention relates to a device for depositing a treatment liquid, such as a weedkiller, on plants, the device comprising a tank for the liquid, a plurality of wicks outside the tank, and elements for transferring the liquid contained in the tank to the ends of the wicks. The tank has a horizontally elongate shape and a cross-section which is very much greater than that of the wicks. The tank forms a ramp integral with a dispensing tube, which is mounted underneath the bottom of the elongate tank, parallel to its longitudinal axis, so that the dispensing tube is fed with liquid from a zone of the tank bottom, preferably adjacent to one of the ends of the tank. The dispensing tube has a cross-section similar to that of each wick, and a plurality of inlets or branches in which the ends of the wicks are immobilized by clamping and sealing devices, so that the remainders of the wicks extend freely outside the dispensing tube and the tank.
