U of W launches new DED research project

Dutch elm disease (DED) has traditionally claimed about 3000 trees per year, but recently, Winnipeg has been losing closer to 6000 trees per year – a significant increase . Rapid removal of the infected elms is one of the best ways to help reduce the spread of the disease to other elms, but in recent years, the City of Winnipeg has been struggling to keep up with the disease.

DED is spread by the elm bark beetle which breeds beneath the bark of elm trees. Some trees hold more beetles than others, and these “brood trees” can act as ground zero for new DED infections. The University of Winnipeg has recently begun a new research project to see how we can identify these brood trees so that they can be removed sooner, and therefore help prevent the spread of DED to neighboring trees.
