Japanese Knotweed s.l. taxa are persistent, pervasive plant Invasive Alien Species throughout the More Economically Developed Nations (MEDCs) of the world: no less so in Wales (UK). The current study will trial 23 current, proven integrated management and control methods in seventy-two 225 m2 (triplicate & control) field trial plots (randomised where possible) at two sites in South Wales and in a series of glasshouse trials in Swansea University. The principal aim of the project is to highlight effective (and ineffective) management and control methods, under highly controlled field and glasshouse conditions. We hope that this approach will help to promote effective management of knotweed under a range of potential site-specific circumstances. Drawing extensively from European and North American experiences with knotweed, this trial should serve as a reference tool for Academics, Land Managers and Local Government to exercise their responsibilities in an integrated, optimised fashion.

Introduced Petasites spp. are of current concern to land mangers in the UK, particularly in sites of conservation importance. The current study will trial 12 physiochemical control methods against Petasites fragrans in twenty-six 1 m2 (duplicate & control) field trial plots (randomised where possible) in Taffs Well nr. Cardiff (South Wales). The principal aim of the project is to highlight effective (and ineffective) management and control methods, under highly controlled field conditions. It is hoped that this approach will help to promote effective management of introduced Petasites spp. under a range of potential site-specific circumstances.

Japanese Knotweed s.l. taxa are persistent, pervasive plant Invasive Alien Species throughout the More Economically Developed Nations (MEDCs) of the world. The current study will trial 21 proven and novel physiochemical control methods in sixty four 225 m2 (triplicate & control) field trial plots (randomised where possible) at three sites in South Wales. The principal aim of the project is to highlight effective (and ineffective) physiochemical control methods, under highly controlled field conditions. We hope that this approach will help to promote effective management of knotweed under a range of potential site-specific circumstances. Drawing extensively from European and North American experiences with knotweed, this trial should serve as a reference tool for Academics, Land Managers and Government to exercise their responsibilities in an integrated, optimised fashion.
