What does the economic level of injury refer to in pest management?

The economic level of injury is a critical concept in pest management, indicating the specific population density of a pest that results in economic damage to crops or plants. This is determined by assessing the extent to which pest presence affects yield, quality, and overall profitability.

When pest populations reach this level, the cost incurred from the damage caused by the pests outweighs the cost of implementing pest control measures. This concept helps farmers and agronomists make informed decisions about when to apply pest management strategies, ensuring that they are economically viable and justified. Understanding this threshold assists in optimizing resource use and minimizing unnecessary pesticide applications, which can lead to environmental and economic benefits.
