Ongoing research

Herbicides labeled for aquatic use can be classified as either contact or systemic (see table). Contact herbicides act rapidly on the tissues contacted, typically causing extensive cellular damage and membrane leakage.

Mechanical control techniques may physically damage shoots, roots, or root crowns of plants to the point where they can no longer survive. Alternatively, mechanical control options can remove the entire plant.
