One more case of Dutch Elm disease has been found in Regina over the past week, taking the total to six cases this year.
On average Regina loses four trees to the disease each year.
Elm bark beetles and elm firewood are the leading causes of the spread of Dutch Elm in Regina.
Russ Eirich the city’s Manager of Forestry, Horticulture and Pest Control says as fall gets closer it becomes more difficult to spot Dutch Elm infected trees.
“Once the heat of the summer goes it just doesn’t flag out anymore, and again we’re going to be heading into the fall period now which makes it incredibly difficult for any crew to really recognize the difference just from an outwards appearance, but we’re going to monitor until the Labour Day, maybe go a week past that,” Eirich said.
Since 1981, including this year only 100 trees have been lost to Dutch Elm, Eirich predicts with the hot dry weather this year ten trees will be identified and destroyed due to Dutch Elm.
The worst year came in 2002, when 14 trees were killed by the disease.
