Caribbean pigeon disease

Caribbean pigeon disease is a specific fungal condition affecting primarily decorative and agricultural crops in tropical environments. The pathogen is identified as a complex of micromycetes that thrive under conditions of high humidity and elevated temperatures, which are typical for island ecosystems in the Caribbean region.

The primary hosts for this pathology include tropical fruit trees and several species of ornamental shrubs. Under conditions of intensive farming, this disease can spread to closely related plant species, causing significant damage to both vegetative biomass and the fruit yield.

The main symptoms of infection include characteristic necrotic spots with a grayish-blue hue, which resemble the plumage of pigeons, hence the disease's name. As the infection progresses, affected tissues become deformed and undergo necrosis, while a sporulating layer of the fungus forms on the surface of the plant epidermis.

Disease development is favored by prolonged rainy periods, poor aeration within plantings, and high plant density. The infection spreads through spores carried by wind, water splashes, and pests that breach the integrity of plant surfaces, creating entry points for the fungal mycelium.

To prevent the spread of this disease, it is recommended to strictly follow agronomic practices: removing plant debris, utilizing resistant cultivars, and ensuring regular ventilation in greenhouses. During outbreaks, systemic fungicides are employed, alongside sanitary pruning of affected branches to reduce the overall infection pressure.
