Title: Vascular contact rotating and stationary abrading electrode devices for electric weed killing

Abstract: Undesirable vegetation or weeds are destroyed by electrical current conducted therethrough by prolonged contact with electrodes. Internal plant tissues of the vegetation are exposed for electrode contact by removal of electrically resistant external layer portions through abrasion of the plant stems or stalks along a path of movement of the apparatus to reduce the electrical energy requirements for plant destroying purposes.
