White Grubs- Zoysia
White Grub Infestation Zoysia Turf Grass (treatment below)


As you can see is an infestation of White Grubs. Now in this situation this sod has only been down 1 month. We received a call to do some work cutting rings around the trees and found the infestation. So it is hard to tell where it came from. However, obviously treatment is needed. kill grubs in the spring (or fall) use carbaryl or trichlorfon and irrigate these are your proper curatives. Your Imidacloprid is your residual. Rate with your insecticides are key. Make sure your reading the label after identifying the grubs and developing an effective mixture. Spring time grubs are coming up to the surface and turn into Japanese Beetles, this is the time for your curative carbaryl or trichlorfon your other "household" curatives sold DONT WORK. The grubs are at their largest state if you don't have the right chemical you will not kill them. Granulars take weeks to activate and if you have the wrong active ingredient at the wrong rate its useless. Would be a good idea to add Imidacloprid to the mixture I always do, some don't. However you imidacloprid is a residual for many other insects you can target and keep off your turf for your client. Your mid summer is when you want to reapply your residual before the fall. You want to prevent larvae from developing and growing over the fall winter months. -CriXus
