Although our understanding of how Erwinia initiate infections in plants has become clear, a comprehensive understanding of how these bacteria rid themselves of noxious antimicrobial agents during the infection is important. Erwinia is a genus of Enterobacterales bacteria containing mostly plant pathogenic species which was named for the famous plant pathologist, Erwin Frink Smith.It contains Gram-negative bacteria related to Escherichia coli, Shigella, Salmonella, and Yersinia.They are primarily rod-shaped bacteria.

Leaves showing symptoms, and infected plants, must be removed and discarded immediately to lower the bacterial count and amount of Erwinia present in a production facility. Erwinia attack can be mistaken for fungal disease:

1. Disinfectants such as bleach or quaternary ammonium compounds should be used on clipping shears, tools, and benches between plantings. Craters may form around the colonies on some media. Plants respond to bacterial infection with a powerful chemical arsenal and signaling molecules to rid themselves of the microbes. Pigments may be produced by some species; ranging from cream, pale yellow to light pink.
