Which is a common symptom of Flavescence Dorée on the fruit or vines?

• A. Grapes become more aromatic
• B. Grapes harden
• C. Grapes develop more acidity
• D. Berries shrivel

Answer: (D)

Flavescence Dorée is a grapevine phytoplasma disease transmitted by leafhoppers that disrupts the plant’s ability to ripen and move sugars to the grapes. Because ripening stalls and the berries lose water, the telltale fruit symptom is that the berries shrivel and desiccate. The other options don’t fit because the disease does not make grapes more aromatic or harder; it impairs ripening and often leads to desiccated, shriveled fruit rather than changes like increased acidity.
