Innovative Foam Weeding Natural and Effective
What are these people doing? Why are they spraying foam on the grass? Are they being idle? In fact, this is a special way of weeding called foam weeding. As the name suggests, it uses foam to achieve the purpose of weeding. Of course, it doesn't rely on any toxicity but high temperature. The foam sprayed from the nozzle has a temperature as high as 90 degrees Celsius. And foam has the function of heat preservation and insulation. It can effectively prevent heat loss and form a high-temperature environment for the lawn. When this foam comes into contact with weeds, the heat will be conducted to the root through the sap and kill the weeds fundamentally. In about 2 to 3 days, the green weeds will wither completely. The main components of foam are vegetable oil, sugar and hot water. There are no chemical agents at all. It is pure natural and pollution-free. There is no need to worry about pesticide residues later. In fact, there is also a similar weeding method called flame weeding. Both use high temperature to burn weeds to death. The difference is that flame weeding is much more simple and crude. The flaming behemoth we see is a real flame weeding machine. Thirty-six flame nozzles spray wildly at the ground. The high temperature generated by the flame can not only burn up the weeds but also remove the rhizomes underground. It uses propane as fuel. The products after combustion are water and carbon dioxide. Similarly, there will be no chemical pollution. In addition to the big one, there is also this small spray gun. It is very suitable for small-area weeding work such as in one's own courtyard and by the roadside.
