Blackleg-like Symptoms of Potato

​In 2014 and 2015 blackleg-like symptoms were observed in some U.S. potato growing areas. The presence of a bacterium of the species Dickeya was confirmed by PCR testing. Symptoms caused from this pathogen may include leaf wilts and tuber soft rots which may extend internally up the vascular system of the stem. USDA APHIS PPQ would like to determine if Dickeya spp. are present in Indiana. If you are a potato grower and have observed the symptoms described here, contact Dan Egel.
