What does a threshold limit indicate?

A threshold limit indicates the specific number of pests that triggers control action. This concept is crucial in pest management, as it helps determine when the presence of pests is significant enough to warrant an intervention to protect crops or other targets. By establishing a threshold, pest management professionals can avoid unnecessary treatments and interventions, focusing resources only when they are genuinely needed.

Setting a threshold limit is based on factors like the type of pest, the level of damage it causes, the value of the crops, and economic considerations. This prevents overreliance on pesticides, promoting integrated pest management strategies that aim to balance environmental health and agricultural productivity.
