NASS indicated that 16% of the rye acreage was planted in Georgia, 21% in Oklahoma and 64% in 

other states in 2011 including Illinois, Kansas, Minnesota, Nebraska, New York, North Carolina, North 

Dakota, Pennsylvania, South Carolina, South Dakota, Texas, and Wisconsin. Winter rye is the 

predominant crop grown and weed spectrum is projected to be the same as found in winter wheat in 

these states.
