DESCRIPTION
WHO CAUSES IT?
Monilinia frutícola and Monilinia laxa are two pathogenic fungi responsible for the disease known as Monilinia or brown rot. These pathogens belong to the phylum Ascomycota and are widely distributed in temperate and subtropical regions. Infection begins when fungal spores, produced in large quantities, are dispersed by wind, water or insects to susceptible flowers or fruits. Once the spores find favorable conditions, they germinate and penetrate plant tissues through wounds or natural openings, such as stomata. Within the host tissue, fungi develop infection structures that degrade plant cells and obtain nutrients, thus forming the characteristic sclerotia and conidia on the affected surfaces, which ensure the continuity of the infectious cycle. During the dormant season, sclerotia and conidia can survive in plant debris, waiting for favorable conditions to restart the infectious cycle in the following growing season.
SYMPTOMS
Monilinia or brown rot seriously affects apricot trees, manifesting itself in various organs of the plant, especially in flowers, fruits and young branches. Initial symptoms on flowers include wilting and premature death, followed by characteristic desiccation. On fruits, the disease manifests itself as brown Taches that spread rapidly, leading to complete decomposition of the affected tissue. Young branches may show canker, with gum exudation and dieback. In infected fruits you can observe:
- Brown Taches that expand rapidly.
- Aqueous decomposition of the tissue.
- Appearance of a grayish mass of spores on the surface.
- Easy detachment of the fruit from the tree.
- Mummification of the fruit, which remains attached to the tree.
- Gum exudation on young branches.
- Withering and death of flowers.
