Grapevine diseases

Grapevine diseases are infections that affect the health and productivity of grapevines, caused by bacteria, fungi, viruses, or pests. Common diseases include powdery mildew, which creates a white coating on leaves; downy mildew, leading to yellow spots and fuzzy growth; and botrytis bunch rot, causing moldy grapes. These diseases can weaken vines, reduce grape yield, and impact fruit quality. Proper vineyard management, such as pruning, good sanitation, and applying appropriate treatments, helps prevent and control these diseases, ensuring healthy vines and high-quality grapes.
