re: What is the best WEED AND GRASS killer I can buy or mix?

Go to your nearest farm supply or co-op. I picked up a 2.5 gallon of Cornerstone (generic Round-Up) the other day for $35. This will last me at least 2-3 years and I spray around my house as well as food plots and trails. Mix 2 oz per gallon of water and you are good to go. If you want a little extra kick add some 24d, but be careful because it drifts like crazy and will take out the neighbor's garden as well as his cotton field. Lol.
