Physical Weed Control Techniques

Where chemical and mechanical weed control is undesirable or not feasible, physical weed control techniques may be the perfect solution.

Weed Barriers
Aquatic Control is the most experienced and largest distributor of benthic weed barrier in the northeast. We distribute Aquatic Weed Net(tm) and several other lines of bottom barriers. These gas permeable barriers are secured to the lake bottom, preventing rooted plant growth. Benthic barriers provide an effective and fairly low cost weed control strategy for small beachfront areas.

Diver Hand Pulling
Diver hand pulling is often used where plant density is low, or in combination with Mechanical Harvesting to "clean up" the edges of a waterbody where the water depth becomes insufficient for the harvester to operate. Diver hand pulling is also recommended in areas where desirable species are intermixed with nuisance or invasive species.

Lake Level Drawdown
Lowering the water level of a waterbody can have a dramatic impact on some nuisance vegetation problems. Drawdown can be used where there is a water control structure that allows the managers of lakes or reservoirs to drop the water level in the waterbody for extended periods of time. In winter, lowering the water level exposes the sediment to both freezing and loss of water. Freezing can have a dramatic impact on aquatic plants that have no overwintering structures such as viable seeds.
