What does threshold determination (economic significance) refer to?

• A. The pest population level at which economic control action should be taken.
• B. The maximum number of pests tolerated on a plant indefinitely.
• C. The time required to apply a pesticide.
• D. The cost of the pesticide per acre.

Answer: (A)

Threshold determination in economic terms means pinpointing the pest density at which taking action becomes financially justified. It’s about starting control before losses from pest damage exceed the cost of control, so you don’t waste resources on unnecessary treatments or wait until damage is already economic. This concept focuses on when to act, not how long a pesticide takes to apply, nor the exact per-acre cost by itself. It also isn’t simply the maximum number of pests tolerated indefinitely; it’s the specific population level where the expected benefit of control just outweighs its cost, given crop value, control effectiveness, and market conditions.
