ABSTRACT:
Apparatus which comprises a housing having a compartment and a shaft, a piezoelectric crystal captured in the compartment of the housing and an actuator assembly slideably disposed in said shaft for selectively applying a compressive force to the crystal is used to kill weeds by impressing a voltage across the roots of the weed. An electrically conductive path is formed between one end of the crystal and ground. A second electrically conductive path is formed between the other end of the crystal and a probe adapted for insertion into the roots of a weed. When a compressive force is applied to the crystal, the voltage generated is passed through the root to ground to kill the root, thereby destroying the weed.
