Bacterial wilt

Bacterial wilt is a complex of diseases that occur in plants such as Cucurbitaceae and Solanaceae (tomato, common bean, etc.) and are caused by the pathogens Erwinia tracheiphila, a gram-negative bacterium, or Curtobacterium flaccumfaciens pv. flaccumfaciens, a gram-positive bacterium. Cucumber and melon plants are most susceptible, but squash, pumpkins, and gourds may also become infected.

Bacterial wilts of tomato, Capsicum (pepper), Solanum ovigerum (eggplant), and Irish potato can be caused by (Burkholderiaceae) Ralstonia solanacearum. Other bacteria in the family Burkholderiaceae can cause bacterial wilt of carnation.

Bacteria in the genus Xanthomonas can cause banana bacterial wilt or bacterial wilt in the genus Agrostis.
