Besides pest suppression, what is a core goal of IPM?

• A. Reduce environmental and human health risk by using least-toxic methods first
• B. Maximize pesticide usage
• C. Eliminate monitoring
• D. Use only chemical methods

Answer: (A)

In IPM, the aim is to manage pests while keeping risks to people, pets, non-target organisms, and the environment as low as possible. That’s why the best choice emphasizes reducing environmental and human health risk by using the least-toxic methods first. Starting with non-chemical options such as sanitation, exclusion, mechanical controls, habitat manipulation, and biological control minimizes potential collateral damage and helps prevent issues like resistance, making pest management more sustainable over time. Pesticides are kept as a last resort, used only when monitoring shows action is needed and when the chosen method poses the smallest risk.

Choosing the option that aims to maximize pesticide usage runs counter to IPM principles, which prioritize reducing chemical inputs. Eliminating monitoring undermines decision-making because you won’t know when a problem requires intervention. Relying on chemical methods alone ignores the value of cultural, mechanical, and biological controls that often provide effective, lower-risk solutions.
