Q&A

DutchTrig is a 100% organic vaccine that protects elms against Dutch Elm Disease. The agent contains specific fungal spores of Verticillium, which activate the elm’s natural defense mechanism.

The vaccine is administered annually in the spring via an injection into the trunk of the healthy elm. This treatment stimulates the tree to develop a defense response against Dutch Elm Disease, similar to a flu shot in humans.

Yes, DutchTrig is safe for humans, animals and the environment. It contains no chemicals or toxins and the mold spores used are not pathogens for humans or animals.

DutchTrig is effective for all elm species and cultivars worldwide, provided the trees are healthy and vaccination is repeated annually. The vaccine works only preventively. Diseased elms or trees infected through root contact cannot be cured with DutchTrig.

Vaccination with DutchTrig should take place annually in spring, preferably at a minimum of 25% leaf development. This is the time when the sap flow starts and the tree can optimally absorb the vaccine.

Treatment with DutchTrig is carried out by trained and certified specialists. Worldwide, the remedy is only applied by professionals approved by idverde Bomendienst.

By using DutchTrig, existing and healthy elms can be preserved, helping to preserve monumental avenues and parks for future generations. It also significantly reduces the cost of removing and replacing diseased trees.
