Black knots are predominantly found on which type of trees?

Black knots are a specific fungal disease caused by the pathogen Apiosporina morbosum, primarily affecting certain species of fruit trees, particularly cherries and plums. This fungal infection manifests as black, elongated galls on the stems and branches of these trees, leading to potential girdling and dieback if not managed properly.

While deciduous trees include a wide variety of species that may be affected by other diseases, black knots are particularly associated with fruit-bearing deciduous trees rather than all deciduous varieties. Coniferous trees and evergreen shrubs are not typically impacted by this type of fungal infection, which reinforces the specificity of black knots to fruit trees. This association with fruit trees is crucial for effective pest management and control strategies, as it allows for targeted preventative measures in orchards and gardens where these trees are cultivated.
