Product Description
Granular submerged-weed control with easier application and clearer sizing
Aquathol Super K Granular is a strong fit when you want contact weed control without liquid mixing or spray gear. The granular format works well for shorelines, coves, lake margins, and targeted pond treatments, while the label’s ppm and acre-foot guidance helps buyers size the job with confidence. It is especially useful where broadcast placement and straightforward rate planning matter.
Key Features & Benefits
| Feature | Benefit |
|---|---|
| 63% dipotassium endothall | Concentrated granular chemistry for serious submerged-weed planning. |
| Granular contact herbicide | No liquid mixing or spray setup for many treatments. |
| Broad submerged-weed fit | Useful across milfoil, hydrilla, naiad, coontail, and pondweed programs. |
| Clear rate structure | PPM and acre-foot guidance make order sizing easier. |

Directions & Dosing Snapshot
| Use Case | Label Rate | Application Notes |
|---|---|---|
| Pondweed spp., whole-water treatment | 0.75 to 3.0 ppm, or 3.3 to 13.2 lbs per acre-foot | Lower rates fit large contiguous blocks and protected coves. |
| Curlyleaf pondweed, whole-water treatment | 0.75 to 1.5 ppm, or 3.3 to 6.6 lbs per acre-foot | Useful low-range guide for early-season planning. |
| Coontail, horned pondweed, milfoil, parrotfeather, water stargrass | 2.0 to 3.0 ppm, or 8.8 to 13.2 lbs per acre-foot | Broad-use submerged-weed rate band. |

| Spot treatments, shorelines, boat lanes, rapid dilution | 3.0 to 5.0 ppm, or 13.2 to 22.0 lbs per acre-foot for many labeled submerged weeds | Higher rates fit smaller areas and faster dilution. |
| Ponds and small lakes with little to no outflow | 7.5 lbs per acre-foot at 1.75 ppm | Perimeter placement, early spring, minimum 24 hours contact time. |
Always follow the full label for complete directions, restrictions, and site-specific requirements.

Used as directed for a 1/4 acrea pond to kill grass typepond weeds. Applied in two separate treatments and added NT-MAX after the first dose. Water is crystal clear and weeds are 90% gone. Thanks!

Our 40 acre industrial lagoon was absolutely covered with duckweed and various shore growth 7 months out of the year. For the last 3 years we have been using 8 gallons of Sonar AS, 120 lbs of Aquathol Super K and 1,200 lbs of NT-MAX. Each year has steadily improved to where, this year, we plan on eliminating the Sonar all together since the Duckweed is now eliminated. We will continue running with 80 lbs Aquathol and 1,200 lbs of the NT-MAX. After that, maintenance plan ahead. Long journey!

Country agent said we had Sago Pondweed so we bought the Aquathol Super K and applied exactly as the label instructed. The product got rid of the Sago Pondweed along with other unidentified growth. Great!
