Dutch Elm Disease (DED) is a fungal disease of elm trees which is spread by the elm bark beetle. DED can affect any elm tree and once infected, the disease always kills – over several seasons or sometimes in as little as three weeks.
One of the most important ways that you can help prevent the spread of invasive pests is to avoid the illegal practice of transporting firewood or wood products from an infested area into and around the province.

The City of Weyburn has a successful DED prevention and control program. The 2020 program includes basal spraying of elm trees in specific areas of the city.
If you are unsure whether your property has an elm tree, or you suspect any elm of having DED, please apply for basal spraying online. The deadline to apply is Sept. 18 for the 2020 DED control program.
