What is the relationship between economic injury level and pest control?

The relationship between economic injury level and pest control is best represented by the idea that it indicates the maximum loss before control measures are implemented. The economic injury level (EIL) is defined as the point at which the cost of pest damage equals the cost of pest control measures. If losses are below this level, it may not be economically viable to take action, while at or above this level, control measures become necessary to prevent unacceptable economic damage.

This concept is crucial for pest management decision-making, as it helps practitioners determine when to intervene based on economic factors rather than solely on pest presence or damage observations. By understanding the EIL, pesticide applicators can make informed decisions that optimize both pest management strategies and economic resources, ensuring that control measures are applied only when they are justified based on potential financial losses.
