A localized area of diseased tissue is termed what?

• A. Lesions
• B. Insect
• C. Insecticide
• D. Ligule

Answer: (A)

The term that describes a localized area of diseased tissue is lesion. In turf health and plant pathology, a lesion is a distinct spot or patch on a leaf, stem, or root where tissue has been damaged or killed by disease, injury, or stress. It’s important because lesions are confined to a small area, helping distinguish them from whole-plant symptoms and guiding diagnosis and treatment decisions. The other terms don’t fit: an insect is an animal pest; an insecticide is a chemical used to control insects; a ligule is a small part at the junction of a grass leaf blade and sheath.
