In IPM, what is the primary goal regarding pest damage?

• A. Eliminate pests entirely
• B. Achieve zero damage
• C. Maintain pest damage at economically acceptable levels
• D. Maximize pesticide use

Answer: (C)

In IPM, the aim is to prevent economic losses by keeping pest damage below the level where it would cost more to control the pests than the damage they'd cause. This means monitoring pests and taking action only when their numbers reach a point where control is economically justified, using a mix of methods—cultural, biological, mechanical, and, when needed, chemical—to keep damage at an economically acceptable level. The economic injury level is the pest density where the cost of damage equals the cost of control, and the economic threshold is the point at which action should be taken to prevent reaching that level. So, the best goal is maintaining pest damage at economically acceptable levels, not eliminating all pests or maximizing pesticide use.
