Reduce Dutch Elm Disease
Any government or organization that owns and manages elm trees can benefit by incorporating Dutch Trig® into their elm management program. DED-related elm tree losses in cities, villages, golf courses and cemeteries can be reduced from 4-14% per year (ambient natural infection rates) to less than 1% per year.
Manage BudgetsDutch Trig® is a cost effective treatment that can easily be integrated into existing DED management plans and budgets. By utilizing induced resistance, treated elms are protected from DED which can eliminate removal, sanitation and replacement costs. Dutch Trig® allows tree managers to make choices regarding DED control and avoid the costs incurred from dead trees. The net benefit to the community is that fewer mature elms die from the disease. With Dutch Trig®, budgets can be used to manage the disease instead of the costly removal and sanitation of diseased trees. How many trees to treat?Dutch Trig® is effective in both large and small groups of elms allowing for flexibility in how treatments can be incorporated into existing DED management plans. Whether it is applied to large groups of standing elms or in a more targeted capacity for the highest value trees, Dutch Trig® can provide the same degree of protection against DED infection. |

The Hague treats approximately 10,500 trees per year out of the 30,000 elm street trees they manage. In addition to the dramatic reduction of disease incidence in the treated group of elms, DED incidence also drops in the non-treated groups of elm trees over a number of years.
Positive MessageMuch like a flu shot, Dutch Trig® is applied annually. Because of the annual spring application of Dutch Trig®, the overall awareness of DED prevention goes up in the community. This activity can help to promote public awareness of the City's desire to prevent DED every year. Any organization or institution that incorporates Dutch Trig® in their DED management program sends a positive message to the community and stakeholders. Some important points are:

Complimentary DED Check-upDutch Trig® treatments are quick and easy to apply. Depending on their locations, hundreds of elms can be treated in one day by a single arborist. The yearly application provides an opportunity to integrate treatment with any ongoing DED detection programs. Furthermore, since the arborist inspects the elm when they are injecting, they can ensure that any other actions needed for the health of the tree can be prescribed. Who can do the Injections?Dutch Trig® can be injected by both City arborists and commercial tree care companies. In many jurisdictions, city arborist crews are trained to do injections. Local tree care companies can also be contracted to do the injections for municipal, private or institutional properties. Community Partnership ProgramsIn cities like The Hague , citizens living in untreated areas will often ask their city foresters to include “their” street elms in the Dutch Trig® program. Where budgets allow, the city will agree to do so, because the extra cost of injecting “one more street” is relatively small. In other cases, a partnership between the city and local residents is arranged where the residents agree to pay for the injections and the city provides the treatment. This approach of cities and homeowners collaborating to protect elm trees has saved many elms around the world! |
