    Idiots.... i sent them an email asking if Acclaim can be tank mixed with calcium acid methanearsonate..... which happens to be the AI in Ortho's "Crabgrass Killer for Lawns". Don't ask about the Ortho.... I got it for no cost... so anyways, I get this response:

    Hello John,

    According to the Acclaim label:

    Broadleaf herbicides such as 2,4-D or MCPP may reduce the effectiveness
    of Acclaim Extra Herbicide. Do not apply Acclaim Extra
    within 21 days following a 2,4-D or MCPP application, or 5 days
    before a 2,4-D or MCPP application.

    We do not recommend a tankmixture of the two formulations. If you have additional questions please, please let us know.

    I TOLD them what the Ortho product was, gave them the AI, and this is what they send back to me, 3 days after my email!

    The ortho is labeled for dallasgrass, and while it's early for it here (we do get some) I have a cheap (free) supply of this stuff.... would be nice if I could use it successfully... any suggestions? What do you folks use for a "general purpose" grassy weed killer? I went with Acclaim based on my Lesco rep's recommendation.... mistake? I've got lawns with quack and goose grass.... would like to settle on one tank mix for grassy weeds, if possible. TIA....

    Vernon is correct about the antagonism between Acclaim & Phenoxy herbicides. However that said, many folks do tank mix.

    It's too bad Quinclorac will never registered NY. We still sell a lot of Trimec Plus in NY for this reason.

    Geeze... is NO ONE reading what I asked? I can READ! I have an Acclaim label! I already KNOW all about how incompatable it is with broadleaf herbicides! Is calcium acid methanearsonate a broadleaf herbicide? NOOOOOOO! :dizzy:

    And you actually think your email was fielded by someone other than a pencil pushing, envelope licking, phone answering nobody??

    They put their lead chemical engineer on your question as soon as they got it. He assembled a team of experts to spend overtime hours in a conference room "brainstorming" your question so they could get you, the valued customer the most complete, concise answer in the timliest fashion(3 days) and the answer you got had nothing to do with your question which was, How is Acclaim's comatibility with a known grassy weed herbicide. What a bunch of Numbnuts!

    Quinclorac is also never going to be registered in Hawaii either. Neither is sulfentrazone(Dismiss). Between the golf courses, sod farms, homeowners and landscapers, hundreds of gallons of MSMA, be it in Trimec Plus or 6 lb MSMA are used every year. The DOA's rationale is quinclorac and sulfentrazone have the characteristics of a ground water pollutant. I fail to see how so much arsenic is any healthier. At least those two chemicals are organic compounds that eventually decompose. Arsenic is forever.

    Whitey, It's a CYA thing. Nobody is going to stick their neck out and say sure go ahead and use it without any direct research backing up that recommendation. Especially so when it's a competitors product. The other question that comes to mind is whether the Ortho label specifically OK's tank mixing with other products? Homeowner labels usually don't.

    Saw you bought a Quick 32 a while back, how's that working? I recently bought a used 36 and after a little TLC I'm pretty happy with it especially for the price.

    I will test spray this mix in my own yard and see how it goes. They do however go into some detail both on the label and elsewhere about how to mix Acclaim with Fusilade, which is not a Bayer product.

    The Quick is a nice machine, especially for the money, but it isn't perfect. The deck tends to clog too easilly when mulching, but this is heavy spring growth too... on the lawns I fert, it's fine, but on the ones with too much N down on them, it's a problem. LOL... that is a total of one Tru-Green customer. I kept them on their promise to use me for apps next year, but I have them on a 5 day cut schedule now. I've also gotten a apple tree anti-fruiting GH app from them, mulch, and ither profitable stuff.

    Back on the Quick, the reverse lever handle broke, and I have to watch out not to scald in sidewalk border areas. That is a fixed deck problem really, but the cut and striping is good. I have too many small gates to have gone with a 36. Put in 14 hours yesterday, so I'm going out a bit late today. Almost time for round 2 here...

    I agree. I happily live with it's shortcomings because it's the best machine that fit my weight/size restrictions (limited trailer space). The 36 fits all but one of my gates but just barely.

    definitely do a jar test. Last year I tried to mix a few grassy cides, MSMA + Drive + Acclaim and had some precipitation. I've mixed Acclaim + Drive with no problems, so it was probably the MSMA. MSMA doesn't like to mix with many others. I don't know about the CMA though, I don't have any experience with that.
