Rural Japanese Knotweed Control

Japanese knotweed is high on the Environment Agencies red list of invasive species in the rural landscape. It out competes all native plant species and will quickly establish and smother large areas. It regenerates by vegetative propagation rather than from seed and even a tiny fragment will take root and grow. It will usually find its way into the rural environment through the practice of fly tipping, the illegal practice of dumping rubbish, garden and building waste in field gate ways and lay-bys.

JKW that has been cut down from a garden or building site is classed as hazardous waste and should be transported buy a specialist waste carrier to a registered waste facility able to deal with it. This is be can expensive and time consuming, and so fly tipping has become a common problem.

I practice a ‘FaST' system approach to treating JKW. Foliar and Stem Treatment. Using specialist equipment I inject neat herbicide into the hollow stems of the plant. This has the advantage of getting into the plant cell quickly, not being affected by the weather and not damaging other plant life in the area.

I can also treat the leaves of the plant by spraying with a conventional professional knapsack sprayer where conditions allow, and also by using a leaf wipe applicator which applies neat herbicide to the leaf surface.

Due to the nature of JKW, it can take  3-5 years to stop its growth with treatment being required every year on any new regrowth that appears.
