Prevention Should not be released in the wild. Dispose of garden and pond waste responsibily. Check vehicles, boats, equipment and clothing for plant fragments when leaving infested sites and clean if necessary. Physical Control Mechanical removal is not recommended as the plant spreads through fragmentation. Chemical Control A recently completed Defra funded research project has shown that treatment with glyphosate herbicide reduces biomass by 75% in one year. This is not sufficient to eradicate the species even with two treatments. However a 97.8% reduction in biomass was ahieved using glyphosate and a non-oil soya sticking agent (codename TFWLM1). This latter product is not yet licensed for use in Britain but may be registered in the near future. To download final report of research project click here |
