APPLICATION AND SPRAYER INFORMATION

Mixing Instructions

• Mix with water having pH of 5 to 7. If pH is higher than 7, use an appropriate buffer to reduce pH to desirable range.
• Fill clean spray tank 1/2 full of desired level with water and add buffering agent if necessary.
• Add the required amount of Clipper Herbicide to the spray tank while agitating.
• Fill spray tank to desired level with water. Ensure that Clipper Herbicide is thoroughly mixed before making applications. Agitation should continue until spray solution has been applied.
• Mix only the amount of spray solution that can be applied the day of mixing. Apply Clipper Herbicide within 12 hours of mixing.

Volume and Pressure

Apply Clipper Herbicide in 5 gals of water per acre, with a maximum spray pressure of 40 PSI. Application at less than 5 gals per acre may not provide adequate weed control. Higher gallonage applications generally provide more consistent weed control.

Nozzles and Nozzle Operation

Use nozzles that produce flat or hollow cone spray patterns. Use non-drip type nozzles such as diaphragm type nozzles to avoid unwanted discharge of spray solution. The nozzle must be directed toward the rear of the aircraft, at an angle between 0 degrees and 15 degrees downward. Do not place nozzles on the outer 25% of the wings or rotors.

Surface Application

Apply Clipper Herbicide as a broadcast spray at 6 to 12 ounces of formulated product per acre plus an adjuvant approved for use in aquatics. Apply Clipper Herbicide in a minimum of 30 gals of water per acre to all areas of the water body where weeds exist. Coverage is essential for effective control as all floating weeds need to be exposed to lethal concentrations in all parts of the water body. Any untreated escapes or re-introductions of plants that were not treated will reestablish in areas where surface weeds had previously been controlled. If a second application is required to provide control, 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.

Clipper Herbicide may be tank mixed with 2,4-D, diquat, glyphosate or other registered foliar applied herbicides for enhanced control of floating and emergent weeds. Consult a manufacturer’s label for specific rate restrictions and weeds controlled. Always follow the most restrictive label restrictions and precautions for all products used when making an application involving tank mixes.

Subsurface Application

Apply Clipper Herbicide at a rate that will produce an initial concentration of 200 to 400 ppb (of active ingredient flumioxazin) in the water column. Clipper Herbicide is rapidly absorbed by target plants, but also breaks down quickly in water with a pH greater than 8.5. The pH of water surrounding mats of submersed vegetation can exceed 8.5 by early to mid-day, due to photosynthetic processes. Application of Clipper Herbicide under these conditions may provide only partial weed control, and regrowth is likely. For best control, apply Clipper Herbicide in a minimum of 30 gals of water per acre in the early morning to actively growing weeds and early in the season before surface matting occurs.
