What is a key pest?

• A. A pest that often reaches damaging densities or can damage at low densities.
• B. A pest that is easy to control.
• C. A pest that only affects ornamental turf.
• D. A pest that never damages turf.

Answer: (A)

A key turf pest is defined by its potential to cause damage even at low populations or to reach damaging densities quickly. This means that even small numbers of these pests can injure turf, and their populations can escalate rapidly if not managed. That’s why scouting and treatment decisions focus on pests with demonstrated damage potential, because delaying action increases the risk of noticeable turf damage or loss of quality. The other ideas don’t capture this risk-based concept: being easy to control isn’t what makes a pest key, a pest that only affects ornamental turf isn’t necessarily a threat to the turf you manage, and a pest that never damages turf isn’t a pest to manage at all.
