Descrição da doença
Botryosphaeria sp. It is a genus of pathogenic fungi that affects various plant species, including avocado. This fungus is known for its ability to survive in plant remains and woody tissues. The sporangia produce spores that are released and dispersed by wind and water. When the spores find a wound or cut on the plant, they germinate and colonize the internal tissues. The fungus develops specialized structures, such as mycelium and pycnidia, that allow it to invade woody tissues, causing necrosis and cellular degradation. Infection can persist for long periods, especially under favorable conditions of high humidity and moderate temperatures. Botryosphaeria sp. It reproduces both asexually, through the production of conidia, and sexually, through ascospores that develop in structures known as perithecia.

Descrição do patógeno
Branch drying or dieback caused by Botryosphaeria sp. In avocado it is a devastating disease that mainly affects the branches and trunk of the tree. The infection begins in wounds or damaged areas of the cortex, where the fungus penetrates and spreads through the vascular system. This causes obstruction of the conductive vessels, preventing the flow of nutrients and water, which leads to the progressive death of the affected branches.
- Branch dieback
- Necrotic lesions in the cortex
- Dark sap exudation
- Cracking and drying of the bark
- Withering of leaves and branches
- Loss of vigor and productivity of the tree
