Define Symptom.

Define Symptom.

• A. Alterations of turf grass as a result of disease
• B. Sign of the actual pathogen
• C. A change in color only
• D. Irregular growth not related to disease

Answer: (A)

Symptoms are the plant’s visible responses to disease or stress. They are the changes you can observe in the plant’s appearance or functioning, such as discoloration, wilting, or abnormal growth, caused by the problem. In this question, the best description is the alterations of turf grass as a result of disease because it captures those observable changes in the plant due to disease. A sign would be something you can see that indicates the pathogen itself, like fungal structures, which is not a symptom. A change in color alone is too narrow to define symptoms, and irregular growth not related to disease wouldn’t reflect a disease-induced change.
