Aquashade® Aquatic Plant Growth Control is an EPA-registered aquatic dye that limits sunlight penetration below the water surface, inhibiting the photosynthesis of submerged weeds and algae before they take hold. It's the go-to choice for professional applicators managing lakes and large ponds. How It Works The precisely blended dye absorbs and filters sunlight in the wavelengths plants need to grow. By reducing light availability below the surface, Aquashade starves submerged aquatic plants of the energy required for photosynthesis — preventing growth without the use of chemicals alone. Key Benefits EPA-registered formula — tested and proven effective Most effective in water deeper than 2 feet Prevents and controls submerged aquatic weeds Compatible with herbicides or algaecides for surface algae and shallow-water plant control Best applied early in the season, before plant germination Application Pour directly into the water. For faster dispersion, apply at multiple points around the treatment site or allow fountains and aerators to run during application. Approved Use Suitable for natural and manmade contained lakes and ponds — including ornamental, recreational, fish-bearing, and fish-farming bodies — with little to no outflow. Safety & Restrictions Wait 1 hour before swimming, irrigation, or animal consumption Do not apply to water intended for human consumption Cannot be shipped to: AK, CA, CT, MA, ME, NJ, NY, VT, or WA
