Tree Canker Disease
Canker is a fungal disease that affects various plants, including trees, vegetables, and fruits. Ascomycota fungi cause it. Apiognomonia errabunda causes canker in oak and various deciduous trees. Tree canker affects both developing shoots and blossoming leaves, covering the entire aerial part of the plant, including leaves and fruits. First of all, the disease is visible on the leaves. The disease progresses rapidly, and the causative agent overwinters on infected stems and is introduced with seeds that are removed from diseased plants. The disease spreads due to the wind and animals and is transferred to clothes, equipment, etc. The rainy environment seriously induces the spread of tree canker disease.
