It is bacteria disease in maize because of whether change.

Most likely, this is Dickeya zeae (formerly known as Erwinia chrysanthemi).

Occurred once in Belgium.

Isolate the strain by dilution plating on any common medium and identify it by PCR and sequencing.

Akarapu,

Have you found the pathogen? Can you describe the smell? Is it fishy? I have met recently a pathogen that smells like salted fish, but not a P. carotovorum.
