ACTION: Harvest and remove nuisance or invasive aquatic plants from a pond by hand or mechanical methods. Collected plants may be placed on shore for composting or other disposal. Hand harvesting is the most labor intensive and is most effective when used in concert with whole-lake control strategies, as a follow-up to prevent re-infestation or re-establishment of large beds of weeds. Scuba divers will be required for hand harvesting large plant beds, or for plants growing in water greater than a few feet deep. Mechanical control strategies use equipment to remove the plants and root systems through cutting, rotovating, or hydroraking. Rotovating or rototilling uses a rototilling machine to cut aquatic plant roots from the sediment and remove them from the lake for whole plant control. Hydroraking is essentially the same technique, but uses a mechanical rake to collect and remove some of the cut material.
