Powdery mildew attacks which part of the grapevine?

Explanation:
Powdery mildew targets the young, actively growing parts of the grapevine. The fungus colonizes the surface of soft, new tissue—like developing shoots, young leaves, and inflorescences—where the epidermis is thin and conducive to rapid fungal growth and spore production. Mature wood such as the trunk and underground roots are less favorable for infection, and while fruit can be affected later, the most conspicuous and common damage occurs on the green growth. Therefore, the primary attacked part is the young green parts of the vine.
