ABSTRACT:
The present invention provides a multi-functional tool for applying a fluid agricultural treatment agent, particularly a liquid herbicide, to different types of plant life in the most effective manner for each type. The tool includes a first spray nozzle mounted on the forward tool head and a switch for discharging liquid through the first nozzle in a direction selected by the user. The tool further includes a cutting blade mounted to its head, and a second spray nozzle positioned proximate to the cutting blade. A second switch for the second spray nozzle is automatically actuated to discharge the liquid agent in a direction towards the leading edge of the blade as the blade cuts into a thick plant such as a tree, and is automatically deactuated as the cutting blade is retracted. The single tool of the present invention enables the user to selectively apply the liquid agent both externally and internally in the manner most effective for the specific plant life being treated.
