The university said in a news release Friday that bacterial leaf streak was found in a field in DeKalb County.

Confirmation of the bacterial disease brings the number of states where it has been found to nine. Iowa, Minnesota and Kansas are among them.

Not much is known about bacterial leaf streak, including how damaging it may be or how to treat it.

Assistant Dean for Agriculture Suzanne Bissonnette says anyone who suspects they have found the disease in a field should send a sample to the U of I Plant Clinic to help researchers figure out how widely it has spread.
