Dutch elm disease was first detected in Belgium by a Dutch researcher at the beginning of the 20th century. This was the starting signal to take measures and look for resistant forms. A decades-long control of Dutch elm disease followed. At the end of the 1980s, in a partnership between the University of Amsterdam, the municipality of Amsterdam and idverde Bomendienst (then still: Arcadis Heidemij Realisatie) a research was started to find a solution. Since the approval of the biological vaccine in 1992, it is now successfully applied in countries such as Germany, Denmark, Norway, Sweden, New Zealand, the Netherlands, the United Kingdom, the United States and Canada.
