Dead Centipede Grass

Centipedegrass (Eremochloa ophiuroides) is a dense-growing grass with a low maintenance level. A native of Southeast Asia and China, the grass has minimal water, fertilizer and mowing requirements. Centipedegrass spreads with stolons and is likely to die from pest infestation.
  1. Identification

    • White grubs are common pests of centipedegrass. The creamy white, C-shaped insects with brown heads are the larval stage of scarab beetles. White grubs hatch from the eggs that the beetles lay in the soil.

    Damage

    • The insects are root feeders and extensively damage grass. Initial symptoms include yellowing and thinning grass. Lawns feel spongy and soft and eventually die in irregular patches that continue to spread with time. White-grub-infested grass starts to invite secondary pests like raccoons, moles and birds that damage grass further.

    Control

    • Use predatory insects like ground beetles and parasitic wasp larvae to control white grubs. Parasitic nematodes from the steinernema or heterorhabditis species are also an effective control option. Chemical control strategies include the use of trichlorfon, imidacloprid or clothianidin on newly hatching grubs.
