Dutch  Elm Disease can be Prevented!

Canadians can now protect elm trees from Dutch elm disease based on the tree’s own natural resistance mechanisms without the use of chemicals. With the Dutch Trig® vaccine, cities, parks and private elm owners will finally have a proven and affordable tool to safely and effectively prevent Dutch elm disease from destroying valuable elms.

What is Dutch Trig®?

Dutch Trig® is a non-chemical, non-toxic, biological control agent, or vaccine. The vaccine consists of a suspension of spores of a very specific strain of Verticillium fungus in distilled water.

With Dutch Trig® you can:

  • Protect healthy elms from contracting Dutch elm disease
  • Protect a large number of elms
  • Reduce costs of protection
  • Reduce amount of chemicals used in the urban environment
  • Minimize wounding of the elm

Injecting with Dutch Trig®:

The method of injecting (inoculation) is safe, fast and uses as little vaccine as possible. The injection tool requires no drilling, plugs or pressurized equipment. Designed to use the tree’s own vascular back pressure, the injecting tool ensures a direct uptake of the vaccine into the current annual ring of the tree. This closed- system, highly efficient injection method ensures that between 100-200 trees can be treated safely by one applicator in a single day.

The Application is:

  • Safe - no hazard for humans or the environment
  • Easy - no drilling or pressurized equipment
  • Fast - average 2-5 minutes per tree

Superior Results:

Ninety-nine percent of annually injected elms are succesfully protected from Dutch elm disease.
