Minnesota Pesticide Applicator Category A Practice Test

Environmental thresholds are the pest levels used to decide when to apply pest control to prevent environmental damage. They’re about protecting ecosystems—waterways, non-target organisms, pollinators, and overall environmental health—by taking into account the potential harm of pesticide use, not just money or cosmetic appearance. Aesthetic thresholds concern cosmetic damage; economic threshold and economic injury level focus on economic loss and the cost of control, not environmental protection. So when the goal is to prevent environmental harm, environmental thresholds are the appropriate concept.
