    hello general grounds,
    I am going to switch every year between merit and mach II.
    we used merit last year with no breakthrough but I wanted to kill the SWW also without making another app.
    next year we will go back to merit to keep mr chinch bug supressed.

    regards,
    pete

    Its a good idea to change the products but be aware, Merit does not provide chinchbug control, unfortunately.

    Yes, merit is not labled for chinch bug But....some reliable sources told me 3 years ago that merit supresses chinch bug and I have found this to be true. See for yourself.

    I wish that was true but I've used Merit quite frequently and can't say its actually stopped chinchbugs, since we've used Talstar or Deltaguard for surface insect control in most chinchbug situations. I know this year chinchbugs have been showing quite frequent and these yards have had both Merit or MachII.

    The label does say that Merit will supress chinch bugs and cutworms.

    I applied merit (granular) at the high rate on a bentgrass green last season and I was suprised to see cutworms only one month later and the half life of merit is like 120 days so I don't always believe what the big companys say....but my personal exp. is that it does supress chinch bugs for about 2 months in central new jerseyand it definately does nothing for sod webworm larva.

    Thanks guys, I did have a discussion with an entimologist today and he did indicate that Merit does have some ability to stop chichbugs. My preference is still to use Talstar or deltagard, since obviously its less cost involved.

    Chinch bug rate is 25% higher.
