Valent Professional Products and Nufarm Americas unveiled Clipper Aquatic Herbicide has been registered for use in California.

According to the companies, the Clipper herbicide is the only PRO inhibitor with proven activity on both floating and submersed plants. It is able to control aquatic plants including hydrilla, Eurasian watermilfoil, curlyleaf pondweed and cabomba as well as floating plants such as duckweed, watermeal, giant salvinia and water lettuce.

“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 Mike Riffle, Ph.D., 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.”

When the herbicide is done controlling weeds, it dissipates from the water column and does not accumulate in the sediment, added the companies.

Available through Nufarm, Clipper can be used in California via foliar and/or surface spray, submersed injection or aerial application.
