New Alfalfa Chemigation Herbicide

Chateau Herbicide Approved for Chemigation on Alfalfa.

Valent U.S.A. Corporation, Walnut Creek has received a chemigation use label for Chateau Herbicide in alfalfa just in time for the fall use season in many states; chemigation registration is pending in California. The chemigation label means growers can save time and money and get immediate herbicide activation for long-lasting control of more than 60 tough weeds. Chateau has a new mode of action for alfalfa, and also offers growers excellent rotational flexibility.

John Pawlak, Valent product development manager, says growers who use Chateau through fall chemigation after their last hay cutting improve the overall efficacy of their treatment and save money by eliminating the fuel and equipment costs associated with a separate application.

"Chemigation ensures immediate activation and incorporation of Chateau into the soil for a more streamlined treatment process," Pawlak adds. "Using chemigation will help growers manage their input costs by reducing the number of trips across the fields."

"Chateau is a preemergence herbicide, and requires at least ¼ inch of water for activation. If you don't irrigate or get rain following a Chateau application, weeds are able to germinate during the time between application and activation, which can lead to escapes," Pawlak says. "Applying Chateau through chemigation guarantees that a grower will get maximum activation. Growers who use Chateau can also rely on the chemistry to stay where it's put because it doesn't leach or volatilize."

Growers who intend to rotate into any of a variety of crops in the spring can use Chateau through chemigation after their final cutting in the fall and be ready to plant again in four months.

"The advantage of applying Chateau in the fall is that you control the winter annuals before they emerge, which can have benefits through the first cutting. And with just a four-month plantback restriction, growers will have no trouble planting into a variety of crops," says Len Welch, Valent field market development specialist."

Chateau contains the active ingredient flumioxazin, a PPO inhibitor that binds to the soil and has low water solubility.
