Powdery mildew damages which parts of the grapevine, contributing to reduced yield?

Explanation:
Powdery mildew causes the most yield loss when it harms tissues that are actively growing and crucial for fruit development. Infection of young shoots stunts new growth, inflorescences can have reduced fruit set, and berries themselves may develop poorly or shrink. When these parts are damaged, the vine’s ability to form a full, well-sized harvest is directly reduced. Leaves can be affected as well, but the immediate impact on yield comes from damage to these growth and fruit-forming tissues, while roots or trunks are less directly tied to the current season’s yield.
