Which condition could indicate that a plant is experiencing injury rather than disease?

• A. Yellow veins
• B. General wilting
• C. Localized damage
• D. Stunted growth

Answer: (C)

Localized damage on a plant typically suggests injury rather than a disease. This type of damage often results from factors such as physical impacts, herbicide exposure, or environmental stressors like frost or extreme heat. When damage is confined to a specific area, it often points to an isolated incident that affects only a part of the plant rather than a systemic issue that a plant disease, which usually presents more widespread symptoms, would cause. In contrast, yellow veins may indicate problems related to nutrient deficiencies or diseases affecting the vascular system, and general wilting can be a symptom of both environmental stress and disease. Stunted growth can also be a result of a variety of conditions including disease, pests, or environmental stresses. Thus, localized damage distinctly signifies an injury, making it the correct choice in this context.
