Description
Precise fluridone control for freshwater weed programs
Sonar Genesis is for buyers who want systemic freshwater weed control with more planning precision than a simple pour treatment. Its 6.3% fluridone formulation fits ponds, lakes, reservoirs, and canals where depth, flow, and target species affect rate selection. It can be metered, sprayed, or used on labeled foliar and sediment sites.

Application Notes |
| Ponds, single application |
30 to 90 ppb |
Use the higher end for dense weed mass, harder species, and ponds under 5 acres with average depth under 4 feet; annual sum max 90 ppb. |
| Whole lakes or reservoirs |
Single: 10 to 90 ppb; split or multiple: initial 4 to 50 ppb |
Lower rates may improve selectivity for Eurasian watermilfoil and curlyleaf pondweed. Split programs should maintain sufficient concentration for at least 45 days; annual sum max 150 ppb. |
| Partial lakes or reservoirs |
30 to 150 ppb single, or split applications |
Use higher rates where untreated water may dilute the zone; within 1/4 mile of a functioning potable water intake, no single application may exceed 20 ppb and split or multiple programs require FasTEST. |
| Canals |
Static: 30 to 150 ppb; moving water: maintain 10 to 40 ppb |
Moving-water programs should hold target concentration for at least 45 days. |
| Dry sediments or floating, topped-out, or emerged vegetation |
Max 4 gal per surface acre per annual growth cycle |
Use 30 to 100 gal spray solution per surface acre on dry sediments; use 20 to 100 gal per surface acre on floating, topped-out, or emerged vegetation. Spot treatments may use up to 5% product by volume when the total rate stays at or below 4 gal per surface acre. |

Label reminder: This chart is an example only for single application planning. The 45 ppb guide values are calculated for planning convenience using the official label formula and should be verified against the full Sonar® Genesis product label before application. Refer to the official label for complete directions, restrictions, annual maximums, potable-water intake rules, irrigation limitations, use-site limitations, permit requirements, and any state or local requirements.

Why Choose a precision liquid fluridone program?
- Systemic reach: Fluridone works through susceptible plants over time instead of only treating exposed top growth.
- Planning control: ppb-based dosing gives buyers a clearer framework for matching acreage, depth, and target weeds.
- Buyer confidence: EPA-registered label directions cover ponds, lakes, reservoirs, canals, and labeled foliar or sediment uses.
