    i recently just started using this product,
    so im still getting familar with it

    but thought id pass on some info for those that havent
    tried it yet,

    i decided to spot treat some weeds at my house
    i mixed up a gallon h20 in my back pack sprayer and
    1oz speedzone, No sticker

    i have a nice variety of weeds at my house , as it always
    comes last(much neglected) after all my customers, anyway
    i mostly sprayed wild violet, dandi, pioson ivy

    1 day later the pioson ivy was bunring down 1st,
    later that day the dandis were looking very ill,
    and 2 days later the violet was about 50% burned down,
    ill post back after a another week,
    im curious if the violet dies or starts recouperating

    I am testing Quicksilver, (carfentrazone) by itself. Same active ingredient as Speedzone Southern, I suspect.

    It burned down violets nicely--but it is a contact herbicide--so the violets may come back from the roots. We will see, later.

    In fact, I heard carfentrazone was dependent on sunlight--and that it would not work in the dark. Mysterious.

    In my experience so far carfentrazone attacked the younger leaves mainly. Not effective on dandelions. Poor on oxalis.
    Fairly effective on ground ivy, veronica, black medic, and oddly enough--nutsedge.

    Not sure about moss--it turned a slightly different color.

    Slight injury to the grass.

    thats interesting, at least your having results on the tough to control
    group of weeds,
    ive been using QS for 3 years, i never have used it solo,
    but mixed with eliminate or drive
    Ive seen dandis laying down after 1-2 hours when spot treating
    in hot sun

    i did look today, and most of the younger wild violet plants are
    completely dead, but the larger plants are not

    I'm using Redzone, and although the violets show a really quick burn and some stem twisting (Due to the 2,4-D, I'm sure) the damned things are thriving within a week.

    Metsulfuron smokes violets.
