What does 'economic threshold' refer to in pest management?

In pest management, the term 'economic threshold' refers specifically to the point at which the population of a pest is high enough that its presence could lead to significant damage to crops or plants. This threshold helps inform decisions on whether control measures are financially justified. It indicates the level of pest infestation at which the cost of damage caused by the pests exceeds the cost of controlling them. This concept is vital because it allows pest management strategies to focus on preventing economic loss rather than eliminating all pests, which may not be economically viable.

By establishing an economic threshold, pest managers can adopt a more strategic approach, monitoring pest populations and determining the most appropriate timing and methods for intervention to protect crops effectively while minimizing unnecessary expenditures.
