New use brings greater ease of application to the flexible, long-lasting herbicide

January 16, 2008

WALNUT CREEK, Calif. (January 16, 2008)–Valent U.S.A. Corporation has received a chemigation use label for Chateau® Herbicide in potatoes. Now in its third use season, Chateau has provided long-lasting and consistent preemergence residual protection against tough weeds, including yield-robbing annual nightshades.

Adding to Chateau's reputation as an excellent herbicide that also allows rotational flexibility, the new chemigation label will mean greater application flexibility for potato growers who may choose to apply Chateau via ground, air or center pivot irrigation.

"Year after year, growers have seen outstanding, season-long results on nightshade and other tough weeds with Chateau," said Trevor Dale, Valent field market development specialist. "Now Chateau will be easier to apply through chemigation, giving growers the flexibility and ease of use they need with the same proven preemergence action they expect from Chateau."

Additionally, chemigation will mean immediate activation and incorporation of Chateau into the soil for a more streamlined treatment process and fewer trips across the fields for resource-stressed growers.

Chateau should be applied at 1.5 ounces per acre, after planting and before crop emergence when the growing tip is at least three inches below the soil surface.

In addition to its superior long-lasting control, Chateau is broad spectrum, farm-friendly (rotational flexibility) and can be used on all potato varieties. It requires minimal PPE and is clean and easy to handle and apply. Chateau contains the active ingredient flumioxazin, a PPO inhibitor that binds to the soil and has low water solubility.
