Embodiment Construction

[0039] see figure 1 , where a weed management device 10 and a tractor 5 (schematically represented) are shown. The weed treatment device 10 comprises a foam generating device 12 intended to be mounted at the rear of the tractor 5 , and a foam dispensing machine 14 intended to be mounted at the front of the tractor 5 . It will be appreciated that the apparatus 10 may instead be mounted on a different agricultural vehicle, which may be a vehicle dedicated for that purpose. The foam dispensing machine 14 is conceived to be mounted at the front of such a vehicle, as this enables the driver to precisely aim the foam dispensing machine to kill weeds between rows of plants, but it will be appreciated Notably, both components of the weed management apparatus 10 could instead be mounted on a trailer towed behind such an agricultural vehicle.

[0040] The tractor 5 includes an engine 6, a cab 7, a three-point linkage 8 at the front, and a power takeoff 9 at the rear. Such features ar...

Abstract

An apparatus 10 suitable for controlling vegetation which apparatus comprises a hot liquid reservoir 28, release means 38 connected to the hot-liquid reservoir and at least one nozzle 74, for applying a stream of foam that contains steam, connected to the reservoir through the release means. The apparatus includes a heating means 34 to keep the liquid hot so the pressure is above atmospheric pressure. The liquid may be pumped by a pump 36 through the hot-water reservoir, the water being heated on demand by heaters within the reservoir. 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.

Description

technical field [0001] The invention relates to a method of controlling vegetation and to a device for carrying out the method. Background technique [0002] Conventionally, vegetation (eg, weeds) is usually controlled by physical removal (eg, human weeding) or through the use of herbicides. Manual weeding can be very hard work. Plants are becoming increasingly resistant to herbicides. In addition, there is growing public opposition to the use of chemicals in the environment, and legislatures are shifting to reduce the use of toxic chemicals as herbicides. Therefore, there is interest in methods of controlling vegetation that do not use synthetic chemicals and avoid human weeding. [0003] Thermal methods have been proposed for weed control. Various methods have been used to provide heat to weeds, for example, hot water, steam, hot air, flames, and hot foam. These methods overcome some of the disadvantages of herbicides, such as spray deflection and soil or groundwater ...
