Rhizome dormancy can be induced by incorrect herbicide application. Where dormancy exists, the Knotweed may look dead above ground (or may not even be visible) but the rhizome system in the ground remains alive ready to send up new shoots when the dormancy is broken.
Japanese Knotweed can identify when it is being attacked either by chemicals or by being chopped down and go into a state of dormancy, and can remain dormant for up to 15 years.
If you suspect that dormant rhizomes might be present on your property, the Japanese Knotweed Agency can assist with a Japanese Knotweed survey which are conducted by qualified and experienced Japanese Knotweed survey specialists and can detect rhizomes in any state that underground.
