Integrated Sanitation Program
Traditionally, people have tried to control Dutch Elm Disease by stopping it from spreading. Many communities, like the City of Winnipeg, have adopted a highly co-ordinated program to try to
save their elms.
Detection is the first step. The earlier the disease can be caught, the quicker it can be stopped.
Some communities and government agencies have designated experts to help make a definitive diagnosis. Contact these experts at the first suspicion of DED. Early detection can help prevent infection of nearby trees.
Dead wood is an ideal breeding ground for the elm bark beetle. Dead wood must be properly removed and destroyed.
Firewood spreads the disease. Storing elm firewood is illegal in many jurisdictions with active DED control programs.
All elm wood should be buried, burned or chipped immediately.
Pruning promotes tree health. Regular pruning helps a tree use its natural defenses against DED. It also removes breeding sites for the elm bark beetle. Click here
