What is an economic injury level in pest management?

The economic injury level (EIL) in pest management is defined as the specific pest population level at which the cost of implementing control measures is equal to the anticipated economic loss caused by the pest. This means that if the pest population reaches this level, the costs incurred to control the pests would exceed the financial impact of the damage they cause. Understanding this concept is crucial for developing effective pest management strategies because it allows decision-makers to evaluate when it is economically feasible to take action against pests.

In practice, determining the EIL helps in finding a balance between pest management costs and crop or product losses, guiding pest control efforts to be both economically viable and environmentally responsible. This also assists in preventing unnecessary treatments, as interventions are done only when justified by the potential economic implications.
