🦠 Grapevine diseases
Fungi, bacteria and viruses that harm the vine and the crop.
Grapevine diseases are illnesses caused by fungi, bacteria and viruses. They damage leaves, berries, wood and roots and can cut the harvest sharply. For growers this is one of the main worries.
The best-known ones are powdery mildew, downy mildew, grey rot, black rot, sour rot and anthracnose. There are also wood diseases, such as esca, and the bacterial Pierce's disease. Viruses cause, for example, leaf roll, while flavescence dorée is caused by a phytoplasma, a bacteria-like organism. Wet and warm weather usually makes fungal diseases worse.
Several measures help: airing the canopy, pruning, healthy planting material and resistant varieties. Some diseases are treated with fungicides, which are products against fungi, but their use is limited by rules. Vine diseases affect wine quality, so protecting the grapes is an important part of vineyard work. Regular inspection of the vineyard helps spot a disease early and treat only the affected areas.
