Boliniaceae

The Boliniaceae family represents a group of ascomycetous fungi that are ecologically significant in the decay of woody substrates. While primarily saprotrophic, certain species demonstrate opportunistic pathogenic behavior, affecting weakened or damaged trees and contributing to the development of serious necrotic lesions on branches and trunks.

The disease is caused by fungi belonging to the order Xylariales, often categorized as bark necrosis or wood decay. The pathogen type is strictly related to the colonization of xylem and phloem tissues, which disrupts the vascular transport of nutrients and water within the host plant upon severe infection.

Visible symptoms include localized bark discoloration, sunken lesions, and the formation of characteristic hard, dark stroma on the surface of the bark. These structures house the reproductive spores, which can be observed during humid conditions. As the infection progresses, branches may become brittle and experience premature dieback.

Environmental conditions conducive to the development and spread of Boliniaceae include high humidity levels and prolonged moisture on plant surfaces. The dissemination occurs primarily through wind-borne ascospores, which enter the plant host through natural wounds, pruning cuts, or frost-related fissures in the bark.

The economic impact of these fungi is significant in forestry and horticulture, as they reduce the overall vigor and lifespan of affected trees. Effective management involves pruning of diseased material, protecting tree wounds with sealants, and maintaining rigorous sanitation protocols to prevent the build-up of fungal inoculum in the orchard or nursery environment.

• Sanitary pruning of infected wood and branches.
• Application of wound dressings to prevent pathogen entry.
• Implementation of regular equipment disinfection.
• Promotion of tree health through balanced fertilization and irrigation.
