Chateau herbicide California-registered for caneberries

Valent U.S.A. ‘s Chateau Herbicide SW has been registered by the California Department of Pesticide Regulation for use on citrus and caneberries.

A preemergence herbicide, Chateau offers growers residual protection against more than 90 annual weeds, including California winter annuals such as shepherd’s purse, chickweeds, fleabane, groundsel, mallow and marestail, according to Valent USA. Chateau has been used commercially since 2005 in California.

This supplemental label will bring California citrus and caneberry growers much needed options for weed-control, said John Pawlak, product development manager at Valent

“Chateau is a valuable new tool for California citrus and caneberry growers because it stays where the weeds germinate to provide consistent and long-term control,” Pawlak said. “Chateau won’t leach, volatilize or co-distillate upward to help ensure long-lasting performance.”

Chateau is farm friendly, weather ready and does not photodegrade in sunlight after application, according to the company. That means Chateau remains active under various weather conditions until a quarter-inch of rainfall or irrigation releases its activity.

Chateau can be applied on more than 40 crops in California, including bearing and non-bearing citrus, caneberries, tree nuts, tree fruit, grapes, alfalfa, cotton, blueberries and strawberries.

The preferred application timing for Chateau is in the fall to maximize the potential for rainfall to activate and set the herbicide, before the weeds emerge and compete with the crop for nutrients. If weeds have emerged at the time of application, Chateau should be applied with a labeled burn down partner.
