A foliar disease would appear on which part of a plant

Explanation:
Foliar means leaf. Diseases described as foliar affect leaf tissue, so symptoms show up on the leaves first—spots, discoloration, lesions, or powdery mildew on the leaf surface. Leaves are the plant part most exposed to air and moisture, making them the usual site for pathogens that invade leaf tissue. Other plant parts—roots, stems, flowers—are affected by diseases named for those parts, not foliar. Therefore, a foliar disease would appear on the leaves.
