Dock & Swim Area Products PRO

What are these products used for?

This is a comprehensive lake weed management program: Dibrox plus Semera or Flumigard will kill floating and submerged weeds, Mizzen will kill algae, and MuckMaid will eat the inches of muck at the bottom of your water. Together, these lake weed control products will make your swim area usable again.

What are the active ingredients?

• Dibrox: diquat dibromide
• Semera and Flumigard: flumioxazin
• Mizzen: copper triethanolamine complex
• MuckMaid: beneficial bacteria, enzymes, and trace minerals

How to get rid of lake weeds and muck?

Mix Dibrox, Mizzen, plus Semera or Flumigard and water in a sprayer and spray over where the weeds and algae are.

Use a scoop to toss MuckMaid pellets into the area where you have muck.

Is granular or liquid better?

Both our Granular Dock & Swim Area Products and the liquid Dock & Swim Area Products give great weed control for lakes or ponds. This PRO option offers the best control of the most weeds.

Are these lake safe weed killers?

The herbicides and algaecide are all registered with and approved by the EPA. They are safe to use in your lake, even with the fish and other wildlife in and around the water.

MuckMaid contains beneficial bacteria, which is also safe for any fish and wildlife.

Will they kill duckweed, algae, and submerged plants?

Dibrox and Semera or Flumigard will kill duckweed and a wide variety of submerged weeds. Mizzen will kill almost any algae.

MuckMaid is not designed to kill plants or algae; it eats the inches of muck at the bottom of your water.

When should I apply these lake weed killers?

Apply Dibrox, Flumigard or Semera, and Mizzen when the water temperature is 60° F or warmer and the weeds/algae are actively growing.

Apply MuckMaid every 2-4 weeks when the air temperature is 50-90° F.

When will I see results after applying these lake weed killers?

After applying Mizzen, you’ll see full results on the algae in 7-14 days. After applying Dibrox and Flumigard or Semera on duckweed, you’ll see results in 5-7 days. For submerged weeds, you’ll see full results in 17-21 days. Because the bacteria in MuckMaid are live and going through a natural process, you’ll see full results in 30-45 days.

Other tips

• Dibrox, Semera, and Flumigard application rates based on a 4 ft. average depth, areas with dense growth or moving water may require a higher rate to be used
• Mizzen application rates are based on a 2 ft. average depth, areas with dense growth may require a higher rate to be used
  • In a pond, if the algae are around the perimeter, treat the whole perimeter
  • In a pond, do not treat more than half of your pond at one time. Wait 10-14 days before applying a second treatment to the remainder of the pond
