Andersons Goosegrass & Crabgrass Control 28.87lb Bag - Professional Weed Killer for Lawns, Golf Courses & Sports Fields - Commercial Grade Herbicide for Tough Weeds

Really expensive but I needed it for my bent grass green.I know its good stuff have used it for years you just have to be careful on the application rate and the lack of spreaders in the chart. I used a cross reference and it was a bit off so make sure you calibrate with something like cat little or smaller if you dont have the spreaders in the chart.
