Cut and inject herbicide control of Japanese Knotweed Fallopia japonica at Rocky Valley, Cornwall, England

Abstract

Highly invasive, non-native Japanese knotweed Fallopia japonica, was successfully controlled, although not completely eradicated, by cut and inject herbicide application in a coastal valley in south-west England. In areas cleared of knotweed infestation, native flora including bluebells Hyacinthoides non-scripta, successfully re-established.
