What is a threshold limit?

Study for the Ontario Pesticide Training and Certification CORE Test. Prepare with multiple-choice questions, get hints and explanations. Ensure readiness for your certification!

Threshold limit is the pest density or damage level at which you should start pest control actions to prevent unacceptable damage or economic loss. It’s a concrete decision point used in integrated pest management to balance effective control with costs and environmental impact. By monitoring pests and crop value, you apply measures only when the population reaches this point, rather than on a fixed schedule.

This isn’t about a legal pesticide concentration limit, nor a vague usage guideline, nor a time to the next inspection.
