Quick Summary

Erwinia is a genus of motile bacteria belonging to the family Enterobacteriaceae. These bacteria are known to be pathogens of plants, causing various diseases such as dry necrosis, galls, wilts, and soft rots.1

Erwinia species are among the infectious agents that cause plant diseases. For instance, Erwinia amylovora causes fire blight in apples and pears, and Erwinia carotovora is responsible for soft rot in many fleshy fruits and vegetables like cabbage, carrots, and celery. Controlling bacterial diseases can be challenging due to the speed at which bacteria invade plants.2

fruit spot
…decays that are caused by Erwinia and some Pseudomonas species are watery to mushy and putrid and follow injuries. Other bacterial and fungal decays (except Pythium and Phytophthora) are generally firm and dry. Fruit-infecting organisms may attack other plant parts. Insects commonly transmit the infecting microorganisms and provide the entry…

Bacterial wilt
…species of the genera Corynebacterium, Erwinia, Pseudomonas, and Xanthomonas, induces stunting, wilting, and withering, starting usually with younger leaves. Stems, which often shrivel and wither, show discoloured water-conducting tissue. A bacterial ooze is often evident when infected stems are cut and squeezed.
