Bean bacterial wilt/ leaf spot/ canker
Curtobacterium flaccumfaciens pv. flaccumfaciens

Bean bacterial wilt/ leaf spot/ canker (Curtobacterium flaccumfaciens pv. flaccumfaciens) is a bacterial pathogen. It was first detected in Colorado in 2007.

Young bean plants may be attacked and are usually killed. The disease is characterized by a wilting of leaves or parts of leaves during the heat of the day and recovery as the temperature drops in the evening. As a result of bacterial plugging of the vessels, the water supply is cut off and the leaves turn brown and abscind.
