Reemergence of Goss’s Wilt and Blight of Corn to the Central High Plains

T. A. Jackson, R. M. Harveson, and A. K. Vidaver

September 2007


Goss’s bacterial wilt and blight, also known as leaf freckles and wilt was first identified in Dawson Co. in south central Nebraska in 1969. The disease was soon identified in 54 Nebraska counties and six bordering states. Widespread development of symptoms in NE, WY, and CO early in the 2006 growing season led to submission of more than 50 samples to the UNL Panhandle Research and Extension Center’s Plant Disease Diagnostic Clinic in Scottsbluff, NE for analysis. Pathogen identification was made based on a combination of test results.
