    if it sod go ahead with a pre-m application, if its seed and has germinated I would wait a couple weeks and apply Dimension.

    I would avoid pre-m's on any new lawn. You wanna get those roots established before the big heat comes. Check with the supplier of the sod. Often they are treated with pre-m's at the sod farm and do not need an additional app for up to one year.

    Enough of the speculation here......

    There is only one preemergent you can safely apply to this new sod, which is Ronstar. Ronstar is not labeled for residential use...so your option is gone unless you are into doing illegal applications.

    What should you do?

    Apply a starter fertilizer now eg 18-24-12, then a couple of weeks later apply Ammonium Sulfate 21-0-0. Apply 21-0-0 again two weeks after that. Your new sod will respond to this in a big way.

    After this series you can apply Vessel at 0.75 oz/M if necessary to control broadleafs.

    There has been two studies that I'm aware of, one particularly from Texas A&M.
    Pendulem will not affect the roots on Bermuda sod unless applied at a minimum of 3X the label limit.
    So, go ahead and apply if you want to - if it was me - I would applied either Momentum or an ester based herbicide to control for weeds now - then apply the Pre-M when the temps are more suitable.
