What does Economic Injury Level refer to?

The Economic Injury Level (EIL) is defined as the lowest number of pests that will cause damage to crops equal to the cost of implementing control measures. Understanding EIL is crucial for pest management as it helps farmers and pest control professionals make informed decisions about when to act against pest populations. By calculating the EIL, one can assess whether the cost of controlling a pest population is justified by the potential damage that could occur if control measures are not taken.

This concept assists in minimizing unnecessary pesticide applications while ensuring that economic viability is maintained. It is a key factor in integrated pest management strategies that aim to balance economic and ecological outcomes. The focus on the relationship between pest density and economic thresholds provides a clear guideline for making financial decisions regarding pest control.
