Bladderwort， coontail， elodea， hydrilla， naiad， pondweed， and watermilfoil. These are just a few of the many problematic species of aquatic weeds that can quickly overrun a pond， lake， canal， or reservoir. When weeds take over a waterway， ecosystems are disturbed and recreational use is often halted. Sonar has become a world leader in aquatic herbicides by successfully combating these nuisances. Now， Sonar offers an even more effective and improved treatment with their Precision Release (PR) formula.

After delivering a strong initial dose of concentrated active ingredient， Sonar PR maintains a higher concentration for an extended amount of time. The stamina of this product is particularly effective for combating more tolerant weeds or for treating more challenging areas of your pond. When applied early in the season， this product provides superior season-long control.

Application rates for Sonar PR pellets vary from 3.2 - 25 pounds per acre for ponds to 4 - 80 pounds per acre for lakes. Minimal post-usage restrictions apply. While there are no restrictions on water use for swimming， fishing， or domestic use following treatment， one should wait 14 to 30 days before using treated water for irrigation purposes. See manufacturer’s label for details.
