Key Features & Benefits
| Feature | Benefit |
|---|---|
| 37.3% diquat dibromide | Concentrated contact chemistry for fast knockdown where you spray it. |
| Non-residual activity | Good fit when you want burndown without a long soil program. |
| Aquatic weed label breadth | Covers floating, marginal, and many submerged weeds in still or slow-moving water. |
| Liquid concentrate format | Flexible for spot, broadcast, and depth-based aquatic treatments. |
| Secondary terrestrial uses | Useful for shoreline edges, noncrop cleanup, dormant turf, and renovation. |
Directions & Dosing Snapshot
| Use Case | Label Rate | Application Notes |
|---|---|---|
| Floating and marginal weeds, spot spray | 2 qts./100 gals. spray carrier (0.5% solution) + 0.25-1.0% v/v approved aquatic wetting agent | Wet target weeds completely; do not spray to runoff; repeat escapes within 2 weeks when needed. |
| Cattails, spot spray before flowering | 8 qts./100 gals. spray carrier + approved aquatic wetting agent | Use before flowering for best fit; repeat if needed for control. |
| Floating and marginal weeds, broadcast | 0.5-2.0 gals./surface acre + 16-32 oz./acre approved aquatic wetting agent | Use enough carrier for thorough coverage; dense mats may need retreatment. |
| Duckweed broadcast | 1-2 gals./surface acre | Fits surface infestations within the floating-weed broadcast program. |
| Submerged weeds | 0.5-2.0 gals./surface acre per 4-foot water depth | Use 2.0 gals. for severe infestations; 14-21 day repeats may be needed; at 1 gal./A program: 1 ft = 0.25 gal., 2 ft = 0.50 gal., 3 ft = 0.75 gal., 4 ft = 1.0 gal.; do not exceed 1 gal./surface acre where water is 2 feet or less. |
| Noncrop or shoreline edge spot spray | 1-2 qts./100 gals. water + nonionic surfactant, or 0.75 fl. oz./1 gal. water | Use on nonflooded pond edges, fence lines, and similar noncrop sites; avoid desirable foliage. |
Always follow the full label for complete directions, restrictions, and site-specific requirements.
Comparison Table
| Alligare Diquat Herbicide | Liquid systemic aquatic herbicide | Copper-based algaecide | Biological pond-treatment program | |
|---|---|---|---|---|
| Primary job | Fast knockdown of floating, marginal, and many submerged weeds | Longer-program control of rooted weeds | Algae control, not a rooted-weed program | Organic-load and sludge management support |
| Action style | Contact herbicide | Systemic / translocated | Contact algaecide | Biological digestion |
| Visible timing | Hours to a few days | Slower, varies by label | Varies by chemistry | Gradual, program-based |
| Residual expectation | Non-residual | Varies by label | Varies by chemistry | Maintenance-oriented, not herbicidal residual |
| Best buyer fit | Quick pond cleanup, shoreline touchups, and mixed weed pressure | Buyers prioritizing longer-season weed programs | Buyers prioritizing algae knockdown over higher-plant control | Buyers reducing organics and repeat growth pressure over time |
Why Choose a Liquid Contact Herbicide?
- Fast contact action: For visible knockdown without waiting on a long residual program.
- One concentrate, many jobs: Handles pond weeds, shoreline cleanup, and selected noncrop burn-down from the same bottle.
- Better planning confidence: Aquatic rates, depth guidance, and water-use intervals help you size and schedule treatments more accurately.

Works Well!
Verified Purchase
Started using diquat in 2023 for duckweed, coontail and grassy type weeds. Product does an effective job. Paired with blue dye, ntmax, hydrothol to take care of the chara. Love it!
Verified Purchase
Product does an amazing job when applied by the label and with surfactant added. I work for an Amusement park and we use the same product there. Good product!
Verified Purchase
Gets rid if the growth and does not bother the fish or ducks.
Verified Purchase
Great control product for all growth in and around our Industrial wastewater lagoons. We apply several times per year to keep growth minimized.
Verified Purchase
Works very well for clearing large areas that have weeds and floating mass. Kills the weeds by the next day.
Verified Purchase
First spray turned the weeds around our youth camp beach area brown. Weeds started coming back 2 weeks later. Sprayed again, same things. Adding aquathol super k and nt-max sludge digester to end this and clean the area.
