The Atarus Stinger, a propane-powered thermal weed control machine prototype, has been introduced to the United States by Australian Company D.J. Batchen. The weed control technology built into the Atarus Stinger is recognized by USDA as an authorized organic production practice, along with other propane-powered weed control technologies. It uses steam-quenched combustion technology, which provides weed control without chemicals, so it fits especially well into an organic operation where spraying is not an option.
Through steam quenched combustion technology, steam is generated instantaneously and mixed with combustion gases. The gases emit from the generator outlets at about 430 degrees Celsius, or 806 degrees Fahrenheit. When the heat is applied to the weed, the temperature of the moisture in the plant cells quickly rises, causing the plant cell structure to rupture. This kills the weed since it prevents nutrients and water from entering the weed’s stalks and leaves.
