White Grubs
Symptoms: Grub injury causes the turf to turn brown in large irregular patches that can be pulled up and rolled back like a carpet, usually exposing the grubs.
What causes damage: Grubs are the larvae or immature stages of several species of scarab beetles. The most important in our state are the Japanese beetle, the Asiatic garden beetle, the oriental beetle and the European chafer. The grubs of these beetles are all similar in form; they have a whitish body with a brown head and, they usually lie in a C – shaped or curled position in the soil. Adults emerge from the ground in late spring to early summer, mate and lay eggs in lawns. Grubs soon hatch from these eggs. In mild weather they live one to three inches below the surface of the lawn and feed on grass roots. In the winter they move deeper as the soil surface freezes. In the early spring they move up, as the soil warms to feed and to complete their development.
What we can do: A Granular insecticide (Dylox) should be applied and watered into the lawn as soon as grubs appear. If damage is extensive it is possible damaged areas of turf will have to be repaired.
