Integrated elm management programme
To retain elms, conducting an integrated elm management programme is essential. In addition to inventories, inspections, phytosanitary measures and monitoring, injecting elms with DutchTrig® is one of the basics in an elm management programme.
DutchTrig® makes it possible to retain existing healthy trees so that greenspaces, long-established tree lined avenues and parks with beautiful mature trees, can be retained for future generations and reduce the cost of sanitation felling.
What is DutchTrig®
DutchTrig® is a biological and organic control agent. This vaccine consists of spores of a specific strain of Verticillium fungus that activates the elm’s natural defence mechanism.
How does it work?
In practice, it can be compared with an influenza vaccination. Instead of making healthy elms sick, DutchTrig® ensures that they respond sufficiently to infection by Dutch Elm Disease. In other words, it induces an immune response. Because elm trees grow a new outer layer of sapwood every year, the treatment has to be repeated every spring.
