Bacterial blight primarily kills which part of the grapevine?

Explanation:
Bacterial blight targets actively growing grapevine tissue, and the most serious and visible damage occurs in the shoots. The pathogen colonizes the young canes and spreads through the vascular system, causing rapid necrosis and dieback of the shoots. This weakness in the new growth reduces photosynthetic capacity and overall vine vigor, making shoots the primary tissue killed. Leaves may show spots, but they’re not the main destructive site, and trunk or root tissues are less commonly the primary targets for this disease.
