System and method for destroying ground pearl

Abstract

A method and apparatus is described for treating ground pearl in infested soil. An apparatus including a plurality of vertically oriented probes having steam outlets in communication with a common source of steam is provided. The probes are arrayed in a plurality of parallel rows with each row including a plurality of probes. The probes are inserted into the soil to a depth of at least 12 inches, and steam is injected through the probes and out of the steam outlets to contact the ground pearl, where all of the soil between said probes is heated to a temperature at least sufficient to kill ground pearl. In a preferred embodiment, the apparatus includes a means for injecting high pressure water or other penetrating fluid into the soil beneath the probes to form holes into which the probes are inserted.
