DESCRIPTION
WHO CAUSES IT?
Cladosporiosis is a disease caused by fungi of the genus Cladosporium, which belongs to the Mycosphaerellaceae family. These fungi are ubiquitous microorganisms commonly found in soil, air, and plant surfaces. The best-known species associated with cladosporiosis is Cladosporium fulvum, although other species in the genus can also cause the disease. Cladosporium fungi are saprophytes, meaning they can survive by feeding on dead organic matter. However, they can also act as opportunistic pathogens, especially under conditions favorable for their growth and development, such as high humidity and moderate temperatures.
SYMPTOMS
Typical symptoms of cladosporiosis in tomato include the appearance of necrotic Taches on the leaves, which may appear dark brown or black. These Taches usually start on older leaves and can spread to the stems and fruits, causing defoliation and reducing the quality and yield of tomato crops.
TEMPERATURE AND HUMIDITY
20°C -25°C

HOW IS IT SPREAD?
Wind, direct contact with infected plants, contaminated irrigation water and spread by undisinfected agricultural tools.

To prevent and control cladosporiosis in tomato crops, it is important to implement integrated pest management practices. This may include crop rotation, use of resistant varieties, weed control, and removal of infected crop residues. Additionally, preventative fungicide treatments can be applied and measures taken to improve air circulation and reduce humidity in the growing environment.
