    I had several lawns last year that had grub damage despit being treated with Lesco's Mach II with 24-5-11. I told my Lesco rep last fall I thought it was happening. He told the Dow rep and she never got back to him or me. This year I am going Merit despite the cost increase. You can't buy customers back.

    Anybody else see less than satisfying results with Mach II?

    at our Turf conference in Jan the university specialists addressed this some. They had been hearing all the negative feedback form Mach II also but could find NO scientific evidence of Mach II resitance or problems wiht the product. They did note that Mach IImay have changed slightly in recent years and that the rates have increased. Timming can be critical wiht any product as welll as rainfall and temps.

    I heard that a few people in Madison area had almost 0% control with Mach II last year. The sales rep said there was a formulation problem and gave some customers Dylox at no extra charge. I used Lesco Bandit (Merit) and it worked great where it got watered in within one day. Had one spot in treated area where sprinkler wasn't working; there was a big round patch of turf infested with Jap beetle grubs. Just reaffirms how important it is to water Merit in immediately.

    I am very familiar with the formulation changes that Mach II has undergone. The company I worked for in 99 had 0% control at .08% AI if I recall. They assured me that the 1.33 was the cure of that problem. It was very difficult to sell me back on that product. I have used it again for 3 seasons now, but this is it. I am not going to let the same product let me down ever again. I invest too much money in grub control products to ever have to accept total catastrophic failure from it...twice.

    I also had some problems with the Mach II. Not last year, but the year before. That is why we went to Merit. No problems at all. Just past the cost on to your customer and give them a guarantee. They like to hear that.

    I was told by a professor at Rutgers Mach 2 really works best with Japanese beetle grubs controlling like 80%, on other grubs it only gets like 40% control at best. Merit seamed to work well on most all grubs comparatively. The key is to identify the grubs your fighting in your location, in central jersey we have mostly oriental beetle grubs.:dancing:

    I think we are primarily Jap beetles, although I have seen my share of European chafers. In recent years though mostly JB.
