Effortless pond weed control with a ready-to-use solution

SePRO Sonar RTU is a ready-to-use aquatic herbicide designed to simplify weed management in ponds, lakes, and water features. No mixing, no spray equipment, and no boat needed—just pour the measured dose into your pond and let the product work. This streamlined approach can save time while supporting a cleaner, healthier-looking water body.

What it targets and how it works

  • Targets duckweed and a range of common aquatic weeds, helping to reduce crowded, green mats on the water surface.
  • Systemic action travels through plant tissue for broader, longer-lasting impact across treated plants.
  • Formulated to be used in residential ponds, farms, and lakes with safety considerations in mind when used as directed.

Key benefits for different environments

  • Residential ponds may experience clearer margins and improved water aesthetics.
  • Farm ponds and lake settings can benefit from a simple DIY option that fits seasonal management plans.
  • Season-long treatment is possible when applied according to label directions, with ongoing monitoring for best results.

Easy dosing and safety at a glance

  • 4 quarts per 1/2 acre at an average depth of 4–6 ft; dosing is straightforward and doesn’t require special equipment.
  • No mixing, no spray gear, and no boat needed—pour the measured dose directly into the water.
  • EPA-approved and non-toxic for fish, pets, and wildlife when used as directed, making it suitable for family-friendly settings.
  • Note: shipments are restricted to AK, CT, HI, ME, NJ, NY, WA, and Canada due to regulatory compliance.

For best results, follow the dosing guidance and monitor weed response over time. Sonar RTU offers a practical option for ongoing pond management without requiring complex application steps.
