Popular Herbicide Registered for California Bearing Citrus and Caneberries
July 28, 2017 Valent U.S.A. announced that Chateau Herbicide SW has been registered by the California Department of Pesticide Regulation for use on citrus and caneberries. The supplemental label is particularly welcome for California growers of bearing citrus fruit, as it’s a new use.
A long-lasting preemergence herbicide, Chateau offers growers residual protection against more than 90 annual weeds, including tough California winter annuals such as shepherd’s purse, chickweeds, fleabane, groundsel, mallow, and marestail. Chateau has been used commercially for more than a decade in California with proven residual activity in various weather conditions.
John Pawlak, product development manager at Valent, said the supplemental label will bring California citrus and caneberry growers much-needed options for reliable, long-lasting preemergence weed control.
“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 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.
