Product Description
Fast, Flexible Aquatic Weed Control for Pond and Lake Jobs
Alligare Flumigard Herbicide helps buyers tackle floating, emerged, and many submerged aquatic weeds with one concentrated WDG format. It stands out when you want fast contact activity, surface or subsurface treatment flexibility, and clearer quantity planning for ponds, canals, reservoirs, marshes, or golf course water features. The 1 lb size is easier to handle for smaller jobs, while 5 lb packaging is also available when the treatment plan expands.
Key Features & Benefits
| Feature | Benefit |
|---|---|
| 51% flumioxazin | Concentrated chemistry for serious aquatic weed knockdown. |
| Water-dispersible granule | Dry format stores, measures, and mixes cleanly. |
| Surface and subsurface use | Lets you match the method to the weed problem. |
| Best on young, active weeds | Early timing supports cleaner, more efficient results. |
| EPA-registered product | Gives buyers label-backed confidence for regulated use. |
Directions & Dosing Snapshot
| Use Case | Label Rate | Application Notes |
|---|---|---|
| Floating and emerged weeds, surface spray | 6 to 12 oz per surface acre | Add an aquatic-approved adjuvant and use at least 30 gallons of water per acre. |
| Subsurface treatment, 1 ft average depth | 1.1 / 1.6 / 2.1 lb per surface acre for 200 / 300 / 400 ppb | Good early benchmark for shallow-water planning. |
| Subsurface treatment, 3 ft average depth | 3.2 / 4.8 / 6.4 lb per surface acre for 200 / 300 / 400 ppb | Use actual average depth to avoid under-ordering. |
| Subsurface treatment, 5 ft average depth | 5.3 / 8.0 / 10.6 lb per surface acre for 200 / 300 / 400 ppb | Higher-depth jobs often push buyers into larger pack planning. |
| Subsurface treatment, 7 ft average depth | 7.4 / 11.1 / 14.8 lb per surface acre for 200 / 300 / 400 ppb | Depth changes product need quickly in broad water bodies. |
Always follow the full label for complete directions, restrictions, and site-specific requirements.

I bought 3 different types of this product ver the last 2 years and they all work well, Just make sure you get the one with the chemical named Flumioxazin at 51.0%.

Just mix with water and a surfactant and you are good to go. A little goes a long way so pricewise, a good deal. Good product at a good price.

I use this for shoreline weed cleanup at our gold club resort. Never fails and works quickly.

Our HOA has 2 ponds that have a serious watermeal issue. The Flumigard does well at killing it off. We use NT-MAX, and Cutrine granular for underwater growth and muck accumulation. Excellent products and helpful company.
