Clipper™ Aquatic Herbicide Registered for Use on Tough Aquatic Plants Provides A

Published on January 28, 2011

WALNUT CREEK, Calif.—Valent Professional Products announced that Clipper™ Aquatic Herbicide has been registered by the Environmental Protection Agency (EPA) for use against a variety of aquatic plants. Clipper provides aquatic managers with a fast, effective and much-needed new tool for selective aquatic plant control and resistance management.

A fast-acting contact herbicide, Clipper is the only PPO inhibitor with proven activity on both floating and submersed plants, providing valuable flexibility for applicators. Clipper selectively controls a number of invasive and nuisance aquatic plants, including submersed plants such as hydrilla, Eurasian watermilfoil, curlyleaf pondweed and cabomba as well as floating plants such as duckweed, giant salvinia, water lettuce and watermeal.

With a new chemistry and a new mode of action for the aquatics market, Clipper plays an important role in herbicide resistance management programs. In addition to providing consistent and effective selective plant control, Clipper works swiftly and then dissipates quickly from the water column and does not accumulate in sediment.

Additionally, Clipper offers reduced personal protective equipment (PPE) requirements compared to many other products, a convenient package size and a non-corrosive, dry, flowable formulation for easy mixing, transport and application.

“The aquatics industry has had very limited options when it comes to selecting an aquatic herbicide for a given problem, and you need new products for resistance management,” said Dr. Mike Riffle, research and development manager for Valent Professional Products. “Clipper provides aquatic managers with a fast and effective new option for controlling a variety of tough plants and a valuable rotation partner for their herbicide resistance management programs.”
