    You unlicensed guys give your self away by the questions you ask. A Certified Operator in Florida would have enough training to know where to look if Imprelis was labelled for St Augustine.

    The label says to spray a test plot on a turf not listed on the label and Dupont is not liable for any plant injury. So....It does not say that it is a violation to spray a turf type not listed. And because residential is listed on the label, it is legal for a PCO to spray this product on St. Augustine residential lawn. So the OP's question is not a bad one. I for one have not applied it, and like OP, would be curious to know if anyone have performed any tests.

    if they do not name st aug as a tolerant turf you can bet it isnt. they do tons of research on these products and if it was tolerable they would include it on the label. They know we would love a new product like this to use on SA. They would make a mint

    I have found some C-3 herbicides that only stress S A at Half Rate. The problem is they only suppress the weeds not control them. Of course application like that only help to build chemical resistances.

    ***Edit, forget this, wrong thread****

    Just probing.

    Wonder if anyone can shed some light on the supposed soil residual properties of Imprellis? How strong of a response could we expect out of the residual? What length of time? Weather affect? What weeds would have control to some degree from the residual effect?

    Curious to know how this applies to Imprelis? Its a group 4 or HRAC group O, a synthetic auxin rather than C-3.
    I'm not questioning your statement, just the context?

    First, C-3 is a 3 carbon bond of Cool Season Turf compared to 4 carbon bond of warm Season turf. Not the classification of Herbicides.

    I was just backing up Olive who was backing me up. We are talking about turf tolerances that were not listed on the label. St Augustine herbicide is a very large market and the reason is S A is very susceptible to herbicides. Trust me if St A isn't listed as Tolerant, then 95% change it isn't

    Ok, I was thinking in terms of imprelis specifically. It has bermuda and zoysia on the label, which of course are C4 plants.

    I would try it myself in a test patch anyway even on bermuda or zoysia. Spotlight was labeled for SA and I'm sure you know that story.
