Valent Professional Products and Nufarm Americas Inc. report that ClipperAquatic Herbicide has been registered by the California Department of Pesticide Regulation for use by golf course superintendents.

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, according to the companies. 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, watermeal, giant salvinia and water lettuce.

With a new chemistry and a new mode of action for California applicators, Clipper plays an important role in herbicide resistance management programs, according to the companies. 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 in California has lacked options for control of tough plants such as duckweed and watermeal as well as invasive species such as water lettuce,” said Dr. Mike Riffle, manager of development and technical services for Nufarm. “Clipper provides these markets with a new mode of action for control of floating and submerged weeds, an effective new tool for invasive species control and versatile application methods for ease of use.”
