When comparing pest damage to irrigation-related damage, which pattern is more typical of pest damage?

• A. Pest damage is typically localized and not limited to dry spots; irrigation damage tends to be more uniform across the area.
• B. Pest damage always covers the entire lawn.
• C. Irrigation damage is always localized to sunny spots only.
• D. Pest damage never affects color change.

Answer: (A)

Understanding how damage patterns form helps separate pest problems from irrigation issues. Pest damage typically appears in patches that are localized and not tied to the irrigation pattern. Pests feed where they are active, which often creates irregular, blotchy spots rather than a uniform spread across the entire area. In contrast, irrigation-related damage follows how water is distributed, so it tends to be more uniform across zones that receive similar irrigation coverage.

So, choosing that pest damage is localized and not restricted to dry spots best captures the common pattern. Irrigation damage, by comparison, would show a more even spread corresponding to the watering pattern. Color changes can occur with pests, so saying pest damage never affects color isn’t accurate.
