HUDDERSFIELD residents are being told to use a new weapon in the fight against Japanese knotweed.
Residents living near Clayton Fields - between Edgerton and Birkby - have been battling to stop the spread of the Asian weed that can grow 10ft high.
The weed spreads quickly and forms dense thickets, killing off native plants and altering ecosystems.
It is very difficult to get rid of and, so far, residents in Clayton Fields Action Group have resorted to chopping the weed down. But they now have a new weapon - Tordon 22 weedkiller.
The group was told to use the chemical at a recent meeting with officers from Kirklees Leisure Services and Kirklees Environmental Unit.
The group wanted expert advice and were told to use Tordon 22 in summer, when the knotweed reaches 1.5m in height.
The weed killer costs £78 per five litres, but the group could soon get help to fund this.
The group will soon become constituted, which means it will be able to bid for grants.
Kirklees councillor Mehboob Khan has appealed for local people to help the group tackle the weed.
He said: "Myself and Clr Annie Smith will be there in summer, spraying the weeds. People are welcome to help.
"It has been a massive problem - if it's not kept under control, the danger is it could spread into people's gardens, allotments and the playing fields of St Patrick's School on George Avenue."
