I have a long history working with knotweeds, beginning after Tropical Storm Irene in Vermont. In the wake of that storm, I was responsible for the removal of 5,000 -6,000 plants from several watersheds throughout the State of Vermont. Since then, I have discovered some of the southernmost knotweeds in the world, and am part of an international team ascertaining the threat of these plants to the wonders of Patagonia. Here in New England, my focus has much more to do with protecting landowners from the unexpected problems knotweeds cause. Depending on the circumstances, this might include damaging structures, killing other plants in the garden, or making your home more prone to flood damage.
