Abstract: A device for killing weeds by application of a high temperature fluid to the weeds includes an elongated applicator chamber having a plurality of fluid discharge openings and an elongated distributing member arranged in the applicator chamber. The distributing member includes at least one fluid inlet and a plurality of distribution openings in fluid communication with the applicator chamber. A method for killing weeds by application of a high temperature fluid to the weeds includes: supplying the high temperature fluid to at least one inlet of an elongated distributing member; distributing the high temperature fluid in a longitudinal direction of the distributing member; transferring the high temperature fluid to an elongated applicator chamber through a plurality of distribution openings; and applying the high temperature fluid to the weeds through a plurality of fluid discharge openings.
