If pest density remains below the action threshold, what is the recommended practice?

• A. Do not apply control measures
• B. Apply preventive pesticide anyway
• C. Reseed the turf
• D. Increase watering dramatically

Answer: (A)

Action thresholds guide management decisions: pesticides are used only when pest levels are likely to cause economic damage. If pest density stays below that threshold, there’s little risk of meaningful injury, so applying control measures isn’t warranted. This approach saves money, reduces environmental impact and non-target effects, and helps prevent resistance by avoiding unnecessary chemical use. It also allows natural enemies to keep populations in check. Keep scouting and maintain good turf health, so you can act quickly if densities rise above the threshold. The other options don’t fit because applying pesticides anyway wastes resources and can cause harm, reseeding doesn’t address pest pressure, and dramatically increasing watering doesn’t control the pest.
