Coral Spot Fungus (Nectria cinnabarina) is a widespread pathogenic fungus that affects a diverse range of deciduous and evergreen trees and shrubs. Recognized by its distinctive coral or orange-red spore-producing structures, this fungus typically manifests on dead or weakened branches, forming small, sunken cankers. The fungus has a complex life cycle involving both sexual and asexual reproduction, with asexual spores (conidia) produced in characteristic pustules, aiding in the disease's spread during wet conditions.
Coral Spot Fungus thrives in humid environments, causing dieback and potentially compromising the overall health of the host plant. Management strategies involve pruning infected branches, maintaining plant health to reduce susceptibility, and practicing good garden hygiene to minimize the presence of the fungus. While specific natural enemies for Coral Spot Fungus are not well-documented, the soil's diverse microorganisms may play a role in suppressing its population. It's important for gardeners and horticulturists to be aware of this fungus's characteristics and adopt preventive measures to mitigate its impact on cultivated plants.
