In the IPM steps for turfgrass, which action involves evaluating the effectiveness of the strategy and keeping records?

• A. Detect pest
• B. Identify pest
• C. Determine the amount of damage and whether it is below or above the tolerance thresholds
• D. Evaluate the effectiveness of the strategy and keep records

Answer: (D)

Evaluating how well a strategy worked and keeping records is about closing the IPM loop. After you’ve detected and identified the pest and assessed whether the damage is below or above your tolerance, you need to see if the management action actually reduced pest pressure and injury. This step asks: did the treatment achieve the desired effect, and by how much? It also involves documenting what was done, when, under what conditions, and what the outcomes were. Keeping these records creates a history you can use to decide whether to repeat, modify, or stop the action in the future, and helps refine thresholds and timing for next time. The other steps focus on finding the pest, identifying it, and judging damage against tolerance — they don’t include measuring results or recording outcomes, which is why this option is the best fit.
