Which of the following is a step in implementing an IPM plan for turf management?

• A. Rely exclusively on chemical controls on a fixed schedule.
• B. Monitoring and identification, action thresholds, prevention, least-toxic controls, evaluation.
• C. Waiting for significant damage before acting.
• D. Applying the most toxic pesticide available when pests appear.

Answer: (B)

In IPM, pest management is a proactive, stepwise approach that combines knowledge, prevention, and selective controls, then checks results to refine the plan. The sequence—monitoring and identification, action thresholds, prevention, least-toxic controls, and evaluation—embodies that approach. You first know what pest you’re dealing with, then decide when action is warranted using thresholds so you act before damage becomes severe. Prevention reduces pest pressure through cultural practices and sanitation, lowering the need for interventions. When you do intervene, you choose the least-toxic, most targeted options first, reserving stronger chemicals as a last resort. Finally, evaluating how well the plan worked lets you adjust for future seasons. This makes IPM efficient, environmentally responsible, and sustainable for turf management.

Relying only on fixed-schedule chemicals ignores the identification, thresholds, and prevention steps and misuses resources. Waiting for significant damage is reactive and can be too late to prevent harm. Using the most toxic pesticide whenever pests appear contradicts the “least-toxic” priority and increases risk to non-target organisms and the environment.
