Establishing the psyllid: field studies for the biological control of Japanese knotweed
Japanese knotweed is highly damaging. It spreads extremely quickly, preventing native vegetation from growing and has significant impacts on infrastructure. Current control methods rely mainly on chemicals. Research however has identified a tiny psyllid from Japan as a suitable and safe agent to control Japanese knotweed in the UK, Canada, the Netherlands and USA. The current aim of this project is to achieve establishment and impact of the psyllid on Japanese knotweed in these countries.
