    i thought about using t-zone in my spot spray back packs this year

    maybe mix it with drive or something that kills CG

    i usually use Q4 in backpacks and trimec in the tank

    but my biggest issue is oxalis and violet, and neither one of those seem to do the trick on those

    so i picked up a gallon of t zone to try, and mixed it in a stihl sg 20 BP sprayer, i mixed 5 ounces in 4 gallons (light rate), i did not use a sticker


    i have a little nutsedge in my own yard so i sprayed that


    my neighbor has violet and oxalis, so i sprayed that as well

    it was about 75 degrees and sunny

    ill post results for anyone interested

    I had good results killing oxalis with T-Zone in tests I did about June 9, 2011. Worked better with surfactant. Not much effect on violets, although adding surfactant helped.

    Check the label--Drive is very effective for violets. (And crabgrass). Only problem is that Drive sometimes settled out in the tank when I used it.

    Let us know what happens under your conditions. Your oxalis will be a little more mature in Ohio, rightDGW ?

    Under my conditions, my hand sprayers cover about 2000 sqft per gallon--so naturally I mix it stronger. Spray some water on cement to find what square feet your backpack covers.

    you are correct some are more mature, but the trimec did knock back a bit of them

    i dont blanket spray with my BPs(unless something breaks ) , so i havent calibrated , i just spot spray

    i used the low rate , because tomorrow i plan on mixing with the high rate and a sticker to spray some other sites to compare results

    I found Surge to be very effective and less expensive. How is T-Zone with 90 degree temps?
