Which statement best describes the role of pesticides and the purpose of integrated pest management (IPM)?

Which statement best describes the role of pesticides and the purpose of integrated pest management (IPM)?

• A. Pesticides control pests; IPM uses monitoring, multiple tactics, and thresholds to minimize usage and environmental risk.
• B. IPM aims to maximize pesticide use to ensure crop yields.
• C. Pesticides are never effective in agriculture.
• D. IPM uses monitoring but ignores thresholds.

Answer: (A)

Pesticides are tools to suppress pests, but IPM aims to manage pest populations while protecting the crop, people, and the environment. In IPM, you monitor pest populations and crop health, establish action thresholds (the pest level at which intervention is warranted), and then use a mix of tactics—biological controls like beneficial insects, cultural practices such as crop rotation, mechanical methods, and, when needed, pesticides chosen for target pests and applied at the right time and dose. The goal is effective control with the least environmental risk, economic cost, and potential for resistance, which is precisely what the statement captures: pesticides can control pests, and IPM relies on monitoring, multiple tactics, and thresholds to minimize pesticide use and environmental risk. The other choices misstate IPM or pesticide role: maximizing pesticide use goes against IPM; pesticides are not never effective; IPM does not ignore thresholds.
