    Abstract: An apparatus and method for removing rooted aquatic weeds. An elongated pole includes a remotely operated arm at its distal end. The arm is movable from a disengaged position to an engaged position. The user pushes the distal end of the pole underwater, until it enters the tendrils of a target weed. The remote control is activated, deploying the arm into an engaged position, generally perpendicular to the pole. Simultaneously, the user begins to rotate the pole until resistance to further rotation is detected. This indicates that the tendrils of the weed have been engaged by the arm. Pushing and pulling forces are applied to the pole, until the user detects that the roots of the weed have been extracted from the soil. Continued rotation of the pole while pulling upwardly brings the weed to the water surface, where it may be pulled completely out of the water.
