Marine Biochemists - A complete Aquatic Management Company

Aquatic Weed Control

There are three basic divisions of aquatic weeds. These are:

• Floating Aquatic Plants - These plants either float freely on the surface deriving their nutrients directly from the water via root systems or cell wall interactions, or they have leaves that float on the surface and are rooted in the bottom sediment. These plants include Duckweed, Watermeal, Water Lilies, Watershield, etc.

• Submerged Weeds - These plants are completely underwater and are generally rooted in the bottom sediment. If flowers exist, they may extend above the surface of the water. Plants in this group include the many species of Pondweed, Naiad, Waterstargrass, Eelgrass (also known as Wild Celery), Watermilfoil, Eurasian Watermilfoil, Coontail, Bladderwort, Elodea/Hydrilla, etc.

• Emergent Weeds - These plants grow in shallow areas of lakes, ponds, rivers, and ditches. Generally rigid, these plants do not need water for support. Some of these plants are not considered truly aquatic, but can survive submerged in water or in saturated soils for extended periods of time. Plants in this group include cattail, spikerush, bulrush, creeping water primrose, purple loosestrife, arrowhead, pickerelweed, waterwillow, etc.

Marine Biochemists offer complete integrated approaches to controlling excessive aquatic plant growth including:

• Chemical treatment programs using EPA and state registered aquatic herbicides including Aquathol K, Clearigate, Hydrothol 191, Navigate (a 2,4-D granular –available in most states) Reward, Sonar AS and SRP, etc.
• Aquatic Vegetation Management Plans
• Watershed consultation including addressing non-point source pollution problems (one of the major contributing factors in nutrient-related algae problems-i.e. green lawns can lead to green ponds). See also Aquatic Consulting.
• Treatment programs for reducing and controlling existing aquatic nutrients. See also Nutrient Regulation/Deactivation.
• Benthic Barrier sales and installation.
• Dock-mounted mechanical weed rolling systems.
• Biological controls.
