As you enter into fall, you may be struck with a horrible realization: “Oh no! I forgot to apply an insecticide for grub control this summer! That’s why my customer’s grass looks like that!”
Preventative grub control is usually done between June 1 and July 15 with one or two applications of an insecticide containing imidicloprid.
If you missed this application, you may start seeing damage from grub larvae. Unfortunately, it’s too late to get control with imidicloprid products. This time of year, grub control switches from being a preventative mentality to a curative control approach.
The damage might be yellowing leaves or turf that pulls up easily with no roots. If this sounds familiar, you can still get 75 percent or more control of larvae with an application of a curative grub control product like Dylox.
Dylox, available from Ewing in a 2.5-gallon container of Dylox 420 SL and a 30-pound bag of Dylox 6.2 granular, contains trichlorfon and works both on contact and when ingested.
Encourage grubs to move to the surface of the soil by watering the day before you plan to apply or spread. Once the Dylox has been applied and watered in with half an inch of water, it begins working immediately, with results in one to three days.
