    What to do, new customer, entire weeds broad-leaf + grassy weeds with thin patches of Bermuda throughout. Temps are mid 70s to low 50s. Spray with 24-d product or A strong mix of MS MA and hope its hot enough to work. The 2 4 -D doesn't get the grassy weeds and I'm afraid that the strong dose of MS MA (to kill all weeds) will harm or kill the thin patches of Bermuda. Should I wait until the temps reach 80s and Hit it with a strong dose of MS MA.

    Why can't you use 24d ?

    I dont think the 2 4 D would get good results on mature weeds, it takes up to three weeks to be effective, and doesnt get grassy weeds like foxtail, brome, tall fescue.

    What does the label read?
    I'd use the msma .
    It's a top kill only and will not harm the root system .
    It's designed for this purpose .
    The bermuda will come back.
    That's all you can do .
    Use a preemergent to control future weeds .
    Use at least 2 different kinds .
    The more the better .

    You could mix them and use a 2-4-D ester.

    Hey guys I need rates/1000, I want to know what is working. Is 1.75oz/1000 a good burn for MS MA with air temps in 80s .

    I would wait on the MSMA, treat now with 2,4-D, fertilize now to strengthen bermuda, and hit it with MSMA in 4-6 weeks and again in a couple of more weeks. 1.75 is a stout rate and would act if temps were high enough. Sounds like you have some large winter weeds cycling out---I wouldn't worry about them at this point. We don't apply MSMA until after May 15 and only then if night temps are 62+ also. I've tried it many times before that date, but have had consistently poor results. I am sure our temps are a little ahead of yours.LOL
