The research project is already under way at the School of Horticulture at Writtle College, led by Dr Pascaline Le Lay and Dr Clive Ireland. Suffolk-based Thurlow Countryside Management, which specialises in invasive plant eradication and control, is collaborating.
The project is being carried out in the recently built research glasshouse and aims to improve methods for the sustainable control of the species.
Dr Le Lay said: "It appears to be more and more important to increase public awareness of Japanese knotweed and to ensure its eradication."
Japanese knotweed was introduced to the UK for ornamental use in the 1800s and spreads so well that it threatens native species.
