Nautique Copper Herbicide, manufactured by SEPRO Technologies, is a chelated copper-based herbicide used to control various aquatic weeds and algae.

This fast-acting aquatic herbicide works by absorbing into the plant's tissue through contact. The copper will disrupt the plant's photosynthesis, starving and killing the plant within 3 to 14 days.

This is safe to use in still or flowing potable and non-potable bodies of water to control a variety of floating, emergent, and submersed weeds and algae.

Tools Needed

 Nautique Copper Herbicide can be used through various application methods for surface and sub-surface spraying. It is recommended to use either a tank sprayer or weighted hose depending on your chosen application method.

How to Use

• Step 1: First, determine which weed or weeds that require control. Then measure the body of water's surface area and depth. Your application rate will vary on targeted plant, plant density, and the water body's volume.
• Step 2: This aquatic herbicide can be applied diluted or non-diluted. Read the label for proper mix and application rates for the body of water's volume and your targeted weed(s).
• Step 3: For surface spraying, target the weed being sure to use adequate spray volume to cover the targeted plant. When spraying flowing water surface, spray the chemical against the flow of water. For sub-surface spraying, it is recommended to use a weighted hose to treat submersed plants. Carefully read ALL label instructions for proper mix and application rates and application methods for your particular needs.

Where to Use
