WHO CAUSES IT?
Pseudomonas corrugata is a phytopathogenic bacteria that affects various plants, including tomatoes. This bacteria can cause a disease known as tomato black marrow or marrow necrosis, which can have a significant impact on the quality and yield of tomato crops.
SYMPTOMS
In tomato, the disease caused by Pseudomonas corrugata manifests itself mainly as necrotic lesions on the leaves, with dark edges and a light brown center. These lesions usually appear on the oldest leaves of the plant and can extend to the stems and fruits, causing the destruction of plant tissue and reduced yield.



TEMPERATURE AND HUMIDITY
20°C - 30°C
80% - 95%
TRANSMISSION PATHS
Contaminated irrigation water, undisinfected agricultural tools, handling of infected plants and dispersal by insect vectors.

Recommendations
To prevent and control the disease caused by Pseudomonas corrugata in tomato crops, it is essential to implement integrated pest management practices. This includes rotating crops, using certified pathogen-free seeds, removing infected plants, and applying preventive treatments such as disinfecting agricultural tools and using irrigation practices that reduce moisture in plant foliage. .
