At one time we had nothing that could kill Johnson grass,,
We tried Pramitol, it did kill the Johnson grass, but, in 3 years, the first plant that would grow in that spot was,,,,, Johnson grass,,,

Johnson grass is next to impossible to kill. BTDT. WE don't have much of it here.
Pramitol is only a single season killer. It does have residual, but if you kill what is there at the root, it would likely appear to work for a few seasons. It's made to kill at the root, and is a bare ground herbicide. However, it too can spread, and with the flooding that drive takes, I still wouldn't use it. It can spread. I'm surprised TSC carries that. I thought you had to have an applicators license to buy it. It must not be full strength.
