    I just noticed this...

    Be extremely careful with weed and feed products on Centipede. Centipede wants a very low pH, around 5, 5.5 or 6. The soil in our area naturally tends to have a very high pH, around 7 or so. Great for Burmuda, terrible for Centipede. Any products with a high center number (6-20-6 for example) are completely wrong. You want a product with a 0 or very low center number. You want a W&F that's designed to be used on Centipede. It will say it right on the bag.

    The stomp and twist method will help with herbicide absorption. It also helps you make sure you didn't miss any plants when finished. Sometimes a large infestation makes this impractical, such as when the entire lawn must be blanket sprayed.

    For Centipede, I would suggest using Speedzone Southern. It will cause no harm to the Centipede at labeled rates.

    Wild garlic is often difficult to remove with one application, so expect to spray some of them again in 4 to 6 weeks.

    we get 2. 4 D with ester at the local farm supply for about 30 for 2.5 gallons if im not mistaken. Works good on onion grass for us. Alot of times if its just patchy we use the stomp and round up meathod. Very important to break the skin tension.

    Same as already stated here.

    The use of Roundup is possible but still somewhat risky. If you over apply Roundup when spot spraying, the bermuda greenup in that actual spot could be delayed.

    2,4-D in Bermuda should work very well.
    Depending upon tiller stage a second application may be necessary.
    I would fertilize first with a good quality SCU coated fertilizer than spray the 2,4-D.
    Momentum in liquid form works well yet if other weeds like clover, garlic, especially dandilions or spurge are present, the most efficacious control I have observed has been with 2,4-D and Dicamba.

    This guy has it right. Metsulfuron is far better than 2-4,d based herbicides at removing onions. It removes many other broadleafs as well as rye and will do some damage on poa. It is soil absorbed and has a little residual effect.

    A warm season lawn sprayed with Simazine and metsulfuron in early winter will stay cleaner longer than almost any other combo.

    Blade is labeled for it and works well but is pricey!

    Thanks for all the advice. Sorry for so long in saying so. I also have had an injury that has put me on my back for a while. Better now than when the grass is in full swing.
