granular aquatic herbicide for bottom-growing weeds is the ideal approach when you need a treatment that sinks to the target zone and supports flexible water-use practices. Harpoon Granular Aquatic Herbicide is designed to work from the bottom up, helping manage bottom-growing, copper-sensitive aquatic plant species in ponds, lakes, and other managed water bodies—especially where you can’t pause irrigation, swimming, fishing, or livestock watering.

Why choose a sinking granular treatment

Unlike products that primarily treat the surface, a granular aquatic herbicide for bottom-growing weeds delivers the active ingredient down through the water column, positioning it where many nuisance species start and spread. This makes it a strong fit for spot treatments as well as broader applications when infestations are established throughout the waterbody.

Target weeds & use cases

• Helps control common submerged and floating nuisance plants such as hydrilla, naiads, coontail, elodea, and water hyacinth.
• In waters with low alkalinity (hardness), it may also control Eurasian watermilfoil, sago, curly leaf, and select weeds in the pondweed family (performance can vary by site conditions).
• Useful for projects where treated water needs to remain usable immediately for irrigation, animal consumption, swimming, or fishing.

Application notes

• Apply as a spot treatment for localized growth or scale up for larger treatment zones.
• Label rate range: 40 to 240 pounds per acre-foot.
• Active ingredient: 9.87% Copper Ethylenediamine Complex.
• Always read and follow label directions, including any site-specific restrictions and best practices.

Please note shipping limitations may apply by location. If you’re planning a program-based approach, a granular aquatic herbicide for bottom-growing weeds can be paired with monitoring and follow-up treatments to help maintain long-term control and reduce regrowth pressure.

FAQ

Q: Can treated water be used right away? A: The product is intended for sites where water use cannot be restricted; follow the label for your specific use and location.

Q: What determines which weeds are controlled? A: Species present, growth stage, water chemistry (including alkalinity/hardness), and coverage all influence results—use the label and local guidance for best outcomes.
