Which statement about white grub control emphasizes soil reach of the insecticide?

• A. Watering in after application
• B. Leaving on the surface
• C. Applying during frost
• D. Applying only in windy conditions

Answer: (A)

White grubs live in the soil and feed on turf roots, so the insecticide has to reach that root zone to be effective. Watering in after application helps move the product from the surface down into the soil where grubs are located, improving contact with the pests and often aiding product activation and distribution through the soil profile. Leaving the product on the surface won’t reach the grubs as effectively and can be washed away or degraded. Applying during frost keeps the soil frozen and slows uptake and movement, and windy conditions cause drift, reducing the amount that reaches the soil. Watering in after application best ensures the insecticide reaches the grub-infested zone.
