Vegetation control method and apparatus |
摘要 |
A method of killing or controlling vegetation particularly along roadside berms involves the application of pressurized hot water from a moving applicator head in close proximity to the ground. The pressurized hot water is applied as jets of hot water from an applicator head at a temperature in the range of 100 DEG C. to 110 DEG C. and the flow rate of about 10 liters/minute supplied from one or more pumps operating at a pump pressure of between 200 to 100 psi. The apparatus is mounted on or in a vehicle such as a van, containing a water tank (1), a boiler (2) arranged to heat pressurized water supplied by a pump (4) under pressure to the boiler (2). The pump (4) is a piston pump which supplies the pressurized water through the boiler to a hand held applicator (5) or optionally a towed boom applicator (6). The hand held applicator (5) has an applicator head inside a shroud so that the pressurized hot water is applied to the surface of vegetation as jets of water within the confines of the shroud.
