Abstract
A method for destroying plants by superheating air, compressing it and using it to melt the plant's waxy cuticular coating while utilizing foam made in the process as an insulating agent. The melting of the waxy layer causes dehydration and death to the plant. The foam has a temperature close to the boiling point of water and surfactant combination. This requires that not only the water but also the compressed air be heated above the boiling point of water to achieve a foam whose temperature is approximately 212.degree. F.
