How do I get rid of johnsongrass?

I've heard two recommendations that make sense. Using glyphosate (RoundUp) formulated for wick-applicators will work, especially if this is a large area and you have access to a tractor. Farm supply stores may have this product and equipment, but following the label directions is paramount. The other remedy is to till the area where the Johnsongrass is growing, pick out any runners that surface, allow the grass to sprout again, till it again, pick out the runners, and continue repeating. This last suggestion takes time and patience, but usually pays off in the end because weeds cannot tolerate being disturbed often. Most other recommendations fall short from what I've read.
