White Grub Damage
Posted by John Penton on Thursday, September 17th, 2009 at 4:56pm.White Grub damage is showing up in Nebraska. The white grub larvae feeds on turfgrass roots causing lawn areas to turn brown and sometimes die if grubs damage a large percentage of the roots. The majority of white grub eggs have hatched and reports by the University of Nebraska is showing numbers similar to past years. However, here in eastern Nebraska the growing conditions have been conducive to Kentucky bluegrass and it is likely preventing or delaying damage. Turfgrass should continue to be inspected for white grubs. If birds are feeding in a lawn, areas torn up overnight from raccoons or skunks, or browning occurs, roll or pull the sod back to look for c-shaped, cream colored, red headed larvae. If eight (8) white grubs are found per square foot, an insecticide application may be justified. At this time of year, Dylox is the insecticide of choice. Do not apply Merit or Meridian at this time of year. As always feel free to give Penton Enterprises a call with any of your lawn care needs.
