Which term describes an observable sign indicating pest activity or environmental stress?

• A. Symptom
• B. Stress Factors
• C. Pore Space
• D. Producer

Answer: (A)

Observing signs of pest activity or environmental stress is about recognizing symptoms. A symptom is any visible change in the turf that signals something affecting its health, such as yellowing or wilting blades, thinning patches, stunted growth, or unusual patch patterns. These signs indicate that pests or environmental factors are at work, prompting investigation for pests or issues like drought, nutrient deficiency, or soil compaction. The other terms don’t describe the observable sign: stress factors are the causes of stress, pore space is a soil property, and producer is simply an organism that creates something, not a sign of turf health.
