    Remember Tupersan only lasts about a month.....Usually enough time to get some seed up and cut.

    I was about to say that.... but I read page two first! Actually, I think you can get 6 weeks out of it, but it does need a follow up app of another Pre-M... the timing is important. Too early with a second pre_m and you will kill the late germinating grass seed, too late and the CB will break through the barrier. I'd follow up thre siduron (Tupersan) with a straight pendi app at 5 weeks.

    Is Prodiamine available straight, not as a combo product? Or the AI in Dimension? I hate straight Pendi.... such a mess.
