Xanthomonas

Under wet conditions, slimy bacterial exudates are typically produced by the lesions on the abaxial surface (underside) of the leaf. This exudate serves as inoculum for new infection.

Brief Description: Infections often
follow major veins, producing long water soaked lesions along
them. When lesions get older, they become necrotic and turn
reddish brown. Older lesions often coalesce resulting in symptoms
that are difficult to distinguish from other foliar diseases such
as Phomopsis leaf blight. Under wet conditions, slimy bacterial exudates are typically produced by the lesions on the abaxial surface (underside) of the leaf. This exudate serves as inoculum for new infection. |
