Flumigard® Aquatic Herbicide

Fast-Acting Treatment for Submerged Aquatic Weeds

Flumigard® is a powerful aquatic herbicide designed for rapid control of unwanted submerged and floating aquatic vegetation. It works as an effective stand-alone treatment or as a tank-mix partner for improved weed control in ponds, lakes, canals, and other managed water bodies.
Flumigard is ideal for targeting tough aquatic weeds such as duckweed, watermeal, Eurasian milfoil, and several other submerged vegetation types.

Key Benefits

• Fast-acting aquatic herbicide
• Excellent for submerged weed control
• Ideal for duckweed, watermeal, Eurasian milfoil, and similar aquatic plants
• Can be used alone or as a tank-mix partner
• Selective herbicide that is not affected by turbid, sediment-rich water
• Non-corrosive fine granule formula
• Mixes with water for easy application
• EPA registered

How It Works

Flumigard delivers rapid knockdown of unwanted aquatic vegetation by targeting problem weeds directly. Its fine granule formulation mixes easily with water, making it convenient for spray applications in ponds, lakes, and shoreline treatment areas.
Because it remains effective in turbid or sediment-rich water, Flumigard is a strong choice for ponds where visibility or suspended material may reduce the effectiveness of other herbicides.

Common Uses

• Duckweed control
• Watermeal control
• Eurasian milfoil control
• Submerged aquatic vegetation treatment
