What is the Economic Threshold (ET) in pest management?

The Economic Threshold (ET) in pest management refers to the level at which control measures must be taken to prevent the pest population from reaching a point where economic damage occurs. This concept is critical in integrated pest management, as it helps determine the optimal time for action to minimize costs and maximize benefits.

Choosing to act at or above the Economic Threshold helps ensure that pest management efforts are both effective and economically viable. If pest populations are below this threshold, it may not be cost-effective to implement control measures, as the associated costs could outweigh the potential economic losses caused by the pests.

Understanding the correct context of ET aids in making informed management decisions that balance economic factors with pest control practices. In pest management programs, this threshold guides practitioners on when to employ treatments based on economic implications rather than simply the presence of pests.
