Disease Details

Name: Twig Dieback

Latin Name: Botryosphaeria berengeriana

Description: It is most often found on limbs that are under stress. The stress may be caused by over-production, defoliation by scab and other foliar pathogens, drought, or excessive shading. Prune out dead wood and destroy it.

Disease Life Cycle: This fungal disease infects through natural openings in the bark or through pruning wounds. The fungus is dormant in the winter, and spores are spread by wind in the spring.

Disease Symptons: Twig death is usually general over a tree except under shady conditions, where it will occur only in the shaded areas. Some limbs may die back as much as 24-30 inches.
