DESCRIPTION
WHO CAUSES IT?
Monilia laxa and Monilia fructigena are phytopathogenic fungi responsible for the disease known as monilinia or brown rot, mainly affecting cherry crops and other stone fruit trees. Both pathogens produce asexual spores known as conidia, which are spread primarily by wind and rainwater. During periods of high humidity, conidia germinate on the surface of flowers, fruits or wounds on the plant, penetrating the tissues and causing infections. Fungi can survive in the form of mycelium in the remains of mummified plants and fruits that remain in the soil or on the tree during the winter. In spring, when environmental conditions are favorable, conidia are released and new infections begin in plant tissues. Additionally, spores can directly infect wounds caused by insects or human activity, facilitating the spread of the disease.
SYMPTOMS
Monilinia or brown rot significantly affects the cherry tree, causing serious damage to both flowers and fruits, which reduces the production and quality of the harvest. Infection can begin in flowers during spring and spread to fruits as they ripen, causing rapid decay and death of infected tissues.
- Appearance of brown Taches on flowers and fruits
- Withering and death of flowers and young shoots
- Development of concentric rings of gray spores in infected areas
- Mummification of affected fruits, which remain on the tree
- Discoloration and necrosis of branches and shoots
- Premature fall of affected fruits

Effective against all types of fungi
- Carry out adequate pruning to eliminate and destroy branches and mummified fruits that can serve as sources of inoculum.
- Apply specific fungicides during the critical stages of cherry tree development, especially during flowering and before harvest.
- Avoid sprinkler irrigation and reduce the density of the plantation to improve air circulation and reduce humidity in the foliage.
- Regularly inspect the orchard to detect early symptoms of the disease and quickly eliminate affected parts.
- Use varieties of cherry trees that are more resistant to Monilia laxa and Monilia fructigena.
- Implement integrated pest management (IPM) practices to control insects that can cause wounds and facilitate the entry of pathogens.
- Maintain good soil health through crop rotations and the incorporation of organic matter.
- Promote biodiversity in the garden to encourage the presence of natural enemies of pathogens.
