Weed killing method, comprises spraying hot water onto weeds, followed by deposition of insulating foam layer

摘要

Water is sprayed onto the weeds at a relatively high temperature, preferably greater than 95 deg.C, and an insulating layer of foam is deposited on the weeds which have been sprayed. An independent claim is also included for the weed removal device (1) for carrying out this method, comprising a water heater (5), a pump (3) for forcing the heated water out of a first nozzle (35), a foam forming device (64) and a second nozzle (44) for applying the foam.
