Itchgrass Identification and Control in Virginia

On October 3, 2007, the Weed Identification Clinic at Virginia Tech received an itchgrass [Rottboellia cochinchinensis (Lour.) Clayton] sample from a cornfield in Westmoreland County, near Montross (Figure 1). Currently, itchgrass is considered a federal noxious weed and the Westmoreland County sample is the first record of this plant in the state of Virginia.
