Tuberculate canker is a plant disease caused by certain fungi, primarily affecting trees and shrubs. It is characterized by the formation of raised, wart-like growths, or tubercles, on the bark. These growths can disrupt the flow of nutrients and water, leading to tree decline or death if left untreated. The disease often occurs in oak and maple trees, particularly in areas with high humidity and poor air circulation. Management typically involves pruning infected branches and improving tree health through proper care. In severe cases, chemical treatments may be necessary to control the spread of the fungus.
