No leaf spots are evident. Eventually, the entire plant collapses on the medium. White runny material oozes from cut stems. Potato: [12]

Once a plant is infected, the bacteria spread through the xylem vessels from the area of infection to the main stem, and the entire plant wilts and dies. Initial symptoms may include the wilting of single leaves and smaller stems. Infected plants may produce a creamy white bacterial ooze when cut.
