Name two common lawn pests and basic management strategies.

• A. Grubs — maintain turf health and apply treatment if thresholds are met; Chinch bugs — ensure proper irrigation; treat if populations reach threshold.
• B. Grubs — monitor soil temperature; never treat; Chinch bugs — ignore irrigation; treat only with soil injections.
• C. Armyworms — spray broadly; Grubs — never treat.
• D. Chinch bugs only — ignore irrigation; treat seasonally.

Answer: (A)

The main idea here is using preventive care together with threshold-based treatment in lawn pest management. Grubs and chinch bugs are two common lawn pests, and the smart approach balances keeping the turf healthy with treating only when pests reach a level that could cause economic damage.

Grubs feed on grass roots, so healthy, well-maintained turf is less susceptible to serious injury. Focus on turf health through proper mowing height, adequate fertility, consistent watering, and good soil conditions. This reduces the damage grubs can cause and helps you avoid unnecessary treatments. When grub numbers meet an established threshold, then apply an approved insecticide or consider approved biological controls, following label directions.

Chinch bugs attack the leaves and are especially problematic when the lawn is stressed by heat or drought. Providing uniform, adequate irrigation helps keep the turf less attractive to chinch bugs and more able to recover from pressure. If chinch bug populations exceed their threshold, treat with an appropriate product at the right time, again following label instructions.

This approach avoids blanket spraying and emphasizes maintaining turf health and treating only when pest pressure justifies it.
