Pesticide Applicator Practice Test – Pass the Wisconsin Exam in 2026

The correct answer is A. Economic injury level.

The economic injury level represents the point at which the cost of pest control equals the revenue loss caused by the pest. This threshold is important for determining when it is economically beneficial to implement pest control measures.

The other options, action threshold, economic threshold, and pest resistance level, all have different meanings and cannot be used interchangeably with the economic injury level. The action threshold represents the level at which pest control measures should be taken to prevent pest populations from reaching damaging levels. The economic threshold is the point at which it becomes more cost-effective to implement pest control measures than to accept crop damage. The pest resistance level is the threshold at which the pest has developed resistance to a specific control method.

Therefore, A is the correct answer because it specifically refers to the point at which the cost of pest control equals the revenue loss caused by the pest.
