What is resistance management in turf pest control?

• A. Rotating modes of action and using higher label rates to boost efficacy.
• B. Focusing on one product to build consistent results.
• C. Constantly applying the same pesticide regardless of pest.
• D. A program to rotate modes of action, monitor pest responses, and use labeled products to slow resistance.

Answer: (D)

Resistance management means planning how you use pesticides so pests don’t quickly adapt and become harder to control. The best approach rotates modes of action so pests aren’t exposed to the same chemical over and over, which reduces the selection pressure that favors resistant individuals. Regularly monitoring pest responses lets you spot declining control early and adjust tactics before resistance takes hold. Using products exactly as labeled ensures proper rates and timing, which preserves efficacy and minimizes unnecessary selection pressure. In turf, this typically involves mixing chemical diversity with nonchemical controls as part of an overall IPM strategy rather than relying on a single product or increasing application rates. The goal is a sustainable, effective program that slows resistance and maintains control over time.
