Clipper Aquatic Herbicide

Clipper Aquatic Herbicide, manufactured by Valent, is a versatile contact herbicide that selectively controls invasive floating and submerged weeds in aquatic environments. 

This specially formulated product contains the active ingredient flumioxazin 51%, which gets rid of aquatic weeds like duckweed or water lettuce by interfering and halting the plants’ production of chlorophyll. 

Clipper Aquatic Herbicide is an effective aquatic herbicide that quickly dissolves in water for easier and less mess during application. Plus, it also avoids sediment buildup in water leading to reduced toxicity in water. 

Tools Needed

You will need a separate mixing container or sprayer tank to mix the product in. It may be applied with a backpack sprayer, hand held sprayer, airboat, helicopter, airplane, or a spray rig. 

How to Use

• Step 1: Determine how much Clipper Aquatic Herbicide you will need to treat your waterbody. To do this, calculate the surface area by measuring (in feet) the surface length and the width and then dividing by 43,560 to get the surface acreage. To treat the surface of water bodies with a water depth greater or less than 3 feet as a surface spray use the rate of 6 to 12 oz. of Clipper Herbicide in 30 gallons of water per surface acre. Refer to the label for specific application rates and restrictions. Do not retreat the same section of water with this product more than 6 times per year or exceed 400 ppb of product during any one application. 
• Step 2: While wearing gloves, mix the proper amount of Clipper Aquatic Herbicide with water that has a pH of 5 to 7. If pH is higher than 7, use an appropriate buffer to reduce pH to desirable range. Fill the sprayer tank with half of the amount of clean water, add the measured amount of product, then fill with the remaining of half water. Throghout this entre process maintain continual agitation to ensure the product has been mixed. Apply Clipper Herbicide within 12 hours of mixing. 
• Step 3: Apply Clipper Aquatic Herbicide as a broadcast spray to all areas of water bodies where weeds exists. If a second application is needed, it is recommended that a treatment be made once the return of these weeds is first observed, but no sooner than 28 days after the last treatment. In areas with dense weed vegetation, treat only 1/2 of the water body at one time and wait 10-14 days before treating the remaining area. 

Where to Use

Clipper Aquatic Herbicide can be used in waters like bayous, canals, drainage ditches, lakes, marshes, ponds (including golf course ponds), and reservoirs with a pH less than 8.5. 

Do not apply to intertidual or estuarine areas. This product may also not be applied in water utilized for crawfish farming. 

When to Use

Use when weeds are present in water bodies and when the pH is less than 8.5. Make applications during the early morning hours to enhance weed control. 

To control weeds like hydrilla in Florida perform applications during the late winter and early spring and or early to late fall.

Do not retreat the same section of water within 28 days of application or more than 6 times per year. 

Safety Information 

Clipper Aquatic Herbicide is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product. 

Special Considerations

If Clipper Aquatic Herbicide is applied to mature topped out hydrilla, it was cause some discoloration and loss of growing tips, but regrowth will be rapid. 

Treated water may not be used for irrigation purposes on food crops until at least 5 days after application. 

Treated water may be used for irrigation purposes on turf and landscape ornamentals as outlined in the Irrigation Restrictions Following Application table on the label. 

There is no post-application holding restriction against use of treated water for drinking or recreational purposes (e.g. swimming, fishing).
