Abstract: An apparatus for controlling weed growing on a ground surface includes a liquid supply system configured to supply hot liquid, and dispensing means are operatively connected to the liquid supply system. The dispensing means are configured to dispense hot liquid to the weed. The liquid supply system includes at least one buffer tank that is configured to store and supply hot liquid, a liquid supply container is connected to the at least one buffer tank, and a direct supply line extends between the supply container and the at least one buffer tank. The direct supply line is configured to supply unheated liquid from the supply container directly to the at least one buffer tank and a hot liquid supply line including heating means for heating liquid supplied from the supply container to the at least one buffer tank. A method for controlling weed growth.

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.
