Cannot ship to AK, CT, ME, NJ, NY, VT, WA, or outside the USA. Whole-Pond, Systemic Action: Sonar is absorbed through the leaves and roots of target plants, traveling throughout their entire system (systemic action), ensuring the entire plant, including hard-to-reach roots, is effectively controlled. Effective on a Broad Spectrum of Weeds: It is highly effective against many troublesome submerged, emergent, and floating weeds, including Duckweed, Eurasian watermilfoil, hydrilla, pondweeds, coontail, and elodea. Long-Lasting, Residual Control: A single application provides season-long control, preventing regrowth for an extended period and reducing the need for multiple treatments. No Dissolved Oxygen Depletion: Unlike fast-acting contact herbicides that kill plants rapidly and can cause a dangerous drop in dissolved oxygen as they decay, Sonar works slowly, minimizing the risk of fish kills from oxygen depletion. Easy-to-Use Liquid Formulation: The "Ready-To-Use" (RTU) liquid formulation is designed for simple application and mixes readily with water for uniform distribution. No Water Use Restrictio
