Subject: Karnal bunt found in Texas outside regulated area
Date posted: June 07, 2001
Source: APHIS
Karnal bunt (KB) was found on wheat from a field in Throckmorton County, Texas, in May 2001. This is the first KB discovery outside a regulated area since 1997. The bunted wheat, found stored in an elevator in adjacent Young County, was isolated from other wheat, and restrictions were placed on the harvesting equipment and the host field. A new regulated area will be established three miles around the field next year. KB-infected wheat was also found recently in the regulated areas of McCulloch and San Saba Counties, Texas; Maricopa County, Arizona; and Riverside County, California. Minor changes in the regulated areas will be made in Arizona and Texas. Wet weather during the wheat flowering period this year favored KB development.
