  • Product Details

    • Available in 16 fl. oz. tip and pour container.
    • Concentrated liquid flumioxazin formula
    • ​US EPA Registration No. 8959-61

  • Application

    • Mix with AB™ Brand Aquatic Adjuvant and Nonionic Surfactant and dilute with water before spraying on floating pond plants for best results.
    • Subsurface plants should be treated by applying the solution (16 – 32 fl. oz. per acre foot) evenly to the plants in the water column by inserting the spray nozzle underneath the water surface.
    • While rapidly absorbed by target plants, Pond-Klear™ Aquatic Herbicide is pH sensitive with an ideal application pH of 5 – 7. Check the pH of the water immediately surrounding the treated plants as it can exceed 8.5 by early to mid-day due to photosynthetic processes. Application of this product under high pH conditions may provide only partial control and regrowth will be likely.
    • Readily tank mixes with most aquatic herbicides and algaecides
