Here is a post form Neric Smith, Landscape and Turfgrass Instructor at Indian Hills Community College in Ottumwa, Iowa. It is my first contact on white grubs for the season. They generally begin to appear in early August and continue into October. If anyone else is seeing them, send me some pictures. I'm counting on less grubs this season because of the heat and the dry conditions, but I may be wrong.
Neric has a growing turf program at Indian Hills. For those of you from that area that may be interested in his program, here is his contact information.

The Heat is one thing to deal with, but add white grubs and things get worse. Attached are pictures of grub damage found this week August 5th on a softball field here at Indian Hills Community College in Ottumwa, IA. It is a Kentucky bluegrass field that was treated on June 4th with a granular fertilizer and Merit insecticide. The field does have plenty of thatch and the application was at the low rate of product. It doesn’t take long with 100 plus temperatures(yesterday) for things to turn brown even with syringing. Dylox will be applied and life will go on! Just thought that I would share and see if anyone else was seeing white grub damage yet?
