Individual study: Cut and inject herbicide control of Japanese knotweed Fallopia japonica in Cornwall, England

Published source details

Ford S. (2004) Cut and inject herbicide control of Japanese knotweed Fallopia japonica in Cornwall, England. Conservation Evidence, 1, 3-5

Summary

Trials at sites infested with the highly invasive Japanese knotweed Fallopia japonica, in southwest England, demonstrated that a cut and inject method of herbicide application is an effective way of controlling the plant. Although not matching the kill of the more commonly used method of foliar spraying, it did allow very selective application. Thus the cut and inject method can effectively avoid damage to non-target species and allows herbicidal treatment near watercourses where foliar spraying may not be permitted.
