Which turf pest is most commonly managed with nematicides?

• A. Chinch bugs
• B. Nematodes affecting roots and turf health (root-knot or sting nematodes, depending on region)
• C. Grubs
• D. Annual bluegrass weevil

Answer: (B)

Nematodes are soil-dwelling pests that attack turf roots, causing feeding injury, impaired water and nutrient uptake, and thinning or yellowing patches. Nematicides are chemicals designed specifically to kill or suppress these soil-dwelling nematodes, making them the go-to option for managing root-knot nematodes and sting nematodes in turf, with the exact species depending on regional soil and climate conditions. The other pests listed are insects whose damage and control fall under insecticides or integrated pest strategies rather than nematicides; chinch bugs, grubs, and annual bluegrass weevils affect the turf differently and are not primarily targeted by nematicides.
