UPI Aquathol K: Aquatic Herbicide


Description:UPI Aquathol K is a highly effective aquatic herbicide formulated with the active ingredient Endothall. It is designed to control a wide variety of aquatic weeds in freshwater environments, including submerged and floating vegetation. Aquathol K is commonly used in lakes, ponds, irrigation canals, reservoirs, and other water bodies to maintain clear and healthy water ecosystems.


Active Ingredient:

  • Endothall (40.3%) — A systemic herbicide that targets the root systems and foliage of aquatic plants, ensuring thorough and long-lasting control.

Benefits:

  • Broad-spectrum control: Effective against a variety of aquatic weeds, including species like Eurasian watermilfoil, hydrilla, and water hyacinth.

  • Systemic action: Absorbed by plants, providing long-term control by disrupting cellular processes, leading to plant death.

  • Targeted application: Can be used to treat both submerged and floating plants, making it versatile in addressing different types of aquatic vegetation issues.

  • Rapid results: Visible plant damage can often be seen within a few days after treatment.

  • Minimal impact on aquatic animals: When used as directed, Aquathol K is generally safe for fish, wildlife, and other aquatic organisms.

Application Rates:

  • Slow Moving Water: Apply 0.45 to 3.2 gallons per acre-foot of water, depending on the severity of the infestation.

Application Method:

  • Aquathol K is a contact herbicide; consequently, apply when target plants are present.

  • Aquathol K may be sprayed on the water or injected below the water surface. It may be applied as a concentrate or diluted with water depending on the equipment.

  • In instances where the plant(s) to be controlled is an exposed surface problem (i.e., some of the broad-leaved pond weeds), coverage is important. For best results, apply the concentrate with the least amount of water compatible with the application equipment.

Restrictions:

  • Do not exceed the recommended application rates. Overuse may result in adverse effects on non-target vegetation and wildlife.

  • Avoid applications near drinking water sources or water used for irrigation, unless permitted by local regulations.

  • Do not apply during fish spawning periods to minimize the risk of disrupting aquatic life cycles.

  • Use only in freshwater environments; not intended for use in brackish or saltwater environments.

  • Re-entry intervals: Wait at least 24 hours after application before allowing contact with treated water.

Safety:

  • Personal protective equipment (PPE): Wear long-sleeved clothing, rubber gloves, and protective eyewear when handling and applying the product.

  • Environmental precautions: Keep away from waterways and ensure proper disposal of any unused product or rinse water to avoid contamination.

  • Storage: Store in a cool, dry place, away from direct sunlight, and keep containers tightly closed when not in use.

  • Emergency procedures: In case of accidental exposure or ingestion, follow safety data sheet (SDS) instructions and seek medical attention immediately if necessary.

By following the recommended application guidelines, UPI Aquathol K provides a safe and efficient solution for managing aquatic weed growth, promoting the overall health and clarity of water bodies.
