Well yesterday morning my governor or something gave out on my Permagreen so I put my new skid to use. Until now I have been using the skid for ants and just small front lawns and side lawns. Spraying Simazine and Speedzone Southern, I treated right at 54K but used right at 60K worth of mix. Is 4-6K a acceptable difference when treating 54K of lawn to you guys that have been pulling hose awhile. I thought .11 or less would be fine. I sure I will get a tad better.
