WHO CAUSES IT?
Nectria galligena or Cylindrocarpon mali are phytopathogenic fungi that affect apple trees, causing the disease known as canker. These fungi can enter the plant through wounds or cuts, establishing themselves in the bark and woody tissues. They develop spores that spread to other nearby plants through wind and water, infecting new wounds on trees. Fungi can remain dormant during dry periods and become active under high humidity conditions.
SYMPTOMS
The canker caused by Nectria galligena or Cylindrocarpon mali causes lesions on the bark of apple trees, causing cracks, wounds and a general weakening of the plant. These lesions can affect the branches, the trunk or even the fruits.
• Lesions and cracks in the bark.
• Wounds on branches and trunk.
• Appearance of an orange powder on the bark.
• General weakening of the plant.
• Increased susceptibility to other infections.
