Tackling Japanese Knotweed


Monday, 23 April 2018

Japanese knotweed (Fallopia japonica) is a fast-growing and strong clump-forming perennial plant native to East Asia in Japan, China and Korea, introduced in Europe as ornamental and forage plant during the early 19th century.

The species is widely distributed in Northern Europe, and has been named as the UK most aggressive and destructive plant, while is also listed as one of the world worst invasive species by the IUCN. Currently is spreading in the North of Portugal, Spain, Italy and the Balkan Peninsula.

Several Japanese knotweed control methods have been proposed and used until now. The College of Science at Swansea University in collaboration with the Complete Weed Control, will conduct one of the largest ever field trials for testing the efficiency of 21 different ways of tackling Japanese knotweed by setting up a series of field trials, using both chemicals and biological control agents.
