Japanese knotweed

Help! We have Japanese knotweed along our fenceline. We have tried cutting it back & digging it out & neither has worked. In fact, it's spreading. I'm going to try round up but hear that even that and/or covering the soil with a tarp could take years to work. Any suggestions? What about the testing they've done on steaming it to death? Thank you! - Laura -
