Abstract

Vegetation such as a weed (45) may be controlled by generating a foam comprising air and an aqueous solution comprising a surfactant; dispensing the foam so as to coat at least a base part of the weed that is to be controlled; and then injecting hot water into the foam (46) so as to contact the weed (45) below or within the coating of foam (46) The hot water causes the weed (45) to wilt and die, while the foam (46) suppresses heat loss from the hot water. The method may be carried out using a portable tool (10) which includes an air blower (14), a container (20) of a concentrate for the aqueous solution, a foam-generating tube (24) ending in an open-topped chute (26). The hot water may be provided through a flexible hose (22) from an external boiler (23), and after being used to produce the foam (46), the hot water be sprayed onto the top end of the chute (26).

The heater (16) is arranged to heat the water in at least two successive stages (66, 67), to an intermediate and then to a final temperature, at least the second stage (67) of the heater being activated in pulses, the frequency and/or duration of the pulses being adjustable to control the resultant temperature. Foaming agent is introduced (18, 40) into the water. Upstream of each hose (22) is a diversion valve (85) connecting to a water return circuit (54) leading back to the water storage tank (14); and the water return circuit (54) includes a heat exchanger (55, 56). The heater (16) may be liquid fuelled. The apparatus can be mobile, for example on a motor-vehicle (12), and it enables a number of people to control weeds separately, using separate lances (24), from the same apparatus (10).

Abstract

An apparatus suitable for controlling vegetation which apparatus comprises a hot-liquid container (28), release means (38) connected to the hot-liquid container (28) and at least one nozzle assembly (100), for applying a stream of foam that contains steam, connected to the container through the release means. The nozzle assembly (100) includes a shroud (102) defining an enclosure around a spraying duct (104) within which are a flow-restricting aperture (113), a primary mixing chamber (114) and a secondary mixing chamber (116) linked by a duct of varying cross-section, and with a turbulence-enhancing structure (124) at an outlet (134) from the secondary mixing chamber. Inlet holes (118) communicate between the primary mixing chamber and the enclosure, so air and steam are sucked into the water stream, and foam is produced. The apparatus is either propelled by or mounted on a vehicle; and during use of the apparatus to control vegetation the vehicle provides power (24) to the heating means.
