Coral spot refers to a plant disease caused by the fungal pathogen Nectria cinnabarina, primarily affecting deciduous trees and shrubs. It is characterized by the development of small, closely grouped, coral-pink or red pustules on the infected plant's stems, branches, or twigs. This disease usually appears during the late summer and continues to thrive throughout the winter months.
The symptoms of coral spot include the formation of raised pustules with tiny pinhead-sized openings, from which spore masses may emerge under moist conditions. As the infection progresses, the pustules can expand and merge, eventually leading to branch dieback or even the death of the entire plant. In severe cases, the disease can cause aesthetic damage to ornamental plants and affect the productivity of fruit trees or the overall health and appearance of other affected species.
To manage coral spot, cultural practices such as proper sanitation and good plant care are essential. Pruning infected branches and improving air circulation can help reduce the pathogen's spread. Applying fungicides during the early stages of the disease might control its progress, although prevention is usually more effective.
Overall, coral spot is a plant disease characterized by the development of coral-pink or red pustules caused by the fungus Nectria cinnabarina. Awareness of this condition is paramount in order to timely implement appropriate management and control measures, thus safeguarding the affected plant's health and minimizing potential damages.
The word "coral" in "coral spot" comes from the Old French word "corail", which is derived from the Latin word "corallum". "Corallum" originally came from the Greek word "korallion".
