If a discussion about IPM mentions economic, functional, or aesthetic significance, which basic step is being described?

• A. Third basic step
• B. First basic step
• C. Fourth basic step
• D. Fifth basic step

Answer: (A)

Deciding when to act is tested here. In IPM, you use action thresholds to determine whether pest levels are causing enough harm to warrant intervention. When a discussion mentions economic, functional, or aesthetic significance, it’s describing how you evaluate the potential impact of pests in those terms and decide if control is justified.

• Economic significance means considering potential monetary losses if the pest is left unchecked.

• Functional significance looks at how damage affects the turf’s growth, vigor, or usable quality.

• Aesthetic significance focuses on appearance, such as color, uniformity, or surface quality.

If the pest presence or damage crosses the point where these factors indicate unacceptable harm, you trigger control measures. This threshold-setting step is what guides whether to act, while the other steps cover identifying the pest, monitoring populations, selecting control methods, and evaluating results.
