    Dylox (trichlorphon 6.2%) is the fastest insecticides on the market that's albeled for use on White Grubs. It is highly soluble, so even moderate amounts of water get it moving into the root zone. It is therefore less likely to bind with thatch.

    Grub mortality is usually less than 24 hours.

    But Dylox only lasts in the soil for 10-14 days. Some Grub species hatch here in Metro NY as early as August 15-21. Others may not hatch until well into late September.

    Timing is the key to Dylox performance. Scout for gubs early & often. Know the life cycle & plan accordingly. Keep in mind that in some years, two treatments could be required to cover the different species that may inhabit your area.

    A local extension agent should be helpful.

    so, would your preference be merit? my programs right now are not set up for multiple insecticide applications. ive always treated for grubs at this time of year and have not had a problem. ive used mach 2, merit, grubex. what would be the chemical of preference?

    We're getting towards the end for Merit.

    Mach2 & Grubex are the same chemical with grubex being a consumer preperation.

    I'd either do Merit in the next week or two, or use Mach2 again.

    Use dylox when grubs are present. Otherwise go with merit or mach 2.

    I thought that the "window" of applying Merit was June to mid July. Wouldnt it be useless to put it down now? I have been using Chlorpyrifos for Grub Controls lately, & had very good results with it last year as a curative.
