I've got a gallon of the REAL Round-Up from the 70's. My Dad got it to use in our garden. It's for real farming. Put just 1/2 tsp. in a 5 gallon spayer of water and sprayed sidewalk and driveway cracks. Three days later it rained. Not only did everything growing up thru the cracks die, everything within a foot of where the cracks met the yard turned to dirt the rest of the summer. You gotta dilute it to dilute it. This gallon is going to last longer than I am.
