White Grubs

We have had scattered reports of white grub injury to turfgrass. This is to be expected because even in a low grub year as this one, there are always scattered hot spots where the grubs are numerous. Many times these will be in a single client's yard in a housing development, or on one fairway and not the others. Sometimes the infestation can be explained by irrigation or other maintenance practices, but usually there is no logical reason.

White grub damage.

White grub populations at this time of year can be controlled with an application of trichlorfon (Dylox), chlorantroniliprole (Acelepryn), or Heterorhabditis bacteriophora nematodes. Each should be watered in soon after application. (Phil Nixon)
