    I live in NC. I sprayed my centipede lawn this spring with Prodiamine and Trimec Southern . I was wondering if it is safe and practical to spray my lawn now with the same 2 chemicals mentioned above. I missed my summer post emergent app.. Thanks guys

    Trimec southern---- 1-1.5 pints per acre with a max of 3 pints per acre per app..max yearly is 6 pints.. i sprayed with 1.5 pints in the spring.. I was afraid the timing of putting down a post emergent in cooler temps in september in NC might harm my centipede lawn.. i do have some bermuda mixed in in some places

    Prodiamine--- 1-2.30 lbs per acre per year.. I put out 1 lb in the spring

    1 pound per/a gets you 6 months control if I recall...I'd have to look, but I think you answered your own question.

    You are ok on the trimec too...you really shoul try Celcius on the centipede.

    What weeds are you seeing that you are putting the trimec down?
    Which weeds are you applying the prodiamine for?

    I'd hold off as our temperatures are cooling down. I'd wait til and try not to spray while the centipede is transitioning to a semi-dormant state.

    Crabgrass, clover dandelions etc. So u think it may harm the grass since we are close to ve transitioning to dormancy
