Purchased the Q4, based upon recommendation, (not cheap). Primary goal was the nutsedge, along with some crab grass and broadleaf weeds. Made sure the sprayer was calibrated, coverage was as expected. Went out and applied the Q4, and results we're disappointing. I'm going to take the blame, as I applied when the heat was near 85 degree's. I should have sprayed in cooler temperatures. But was excited with trying the Q4 and a new tow behind sprayer.
I saved a bit and will apply with the hand wand in a few weeks, to the really bad area's of nutsedge. Not giving up on Q4 as yet. What did I learn? Be patient, read the instructions, and not try to hit the home run. Take on one major weed at a time, knock it out, do prevention, and move onto the next weed.
Last year went after the crab grass with DLR8, great product by the way...
