Granular Copper Tea should be spread where for best control?

• A. Directly over nuisance vegetation.
• B. Along the shoreline only.
• C. In deep water only.
• D. At the bottom sediment.

Answer: (A)

Granular copper products work best when they make direct contact with the target plants. Spreading the granules over the nuisance vegetation ensures the copper ions are released right onto the leaves and stems, allowing the plant to absorb them and die more effectively. If you place the product along the shoreline, in deep water, or at the bottom sediment, much of the granules won’t come into contact with the plants. They can settle into the sediment or drift away, reducing efficacy and potentially affecting non-target organisms. So, direct application over the nuisance vegetation provides the strongest, quickest control.
