DRUMHELLER, May 26, 2015 - The Black Knot Fungus on Mayday, Chokecherry and
Schubert Chokecherry trees is widespread across the Province. The Town of
Drumheller has been proactive in the eradication of Black Knot Fungus on our trees for
the last ten (10) years within the limit of our resources. In order to control the spread of
this fungus, the Town is asking homeowners to examine their trees for this fungus as
seen in the picture below. Homeowners can also be proactive by pruning off infected
branches 2-4" below each "knot" and dispose of them in the landfill. Although the best
time is during late winter when the abnormal "knotty" growths are easy to see, we are
asking homeowners to carry out this work now to limit its spread from plant to plant. The
fungus is transported by spores so the proper sanitization of pruning tools is also very
important. Ensure your pruning tools are sanitized after you have carried out this work.

Parks Staff Penny Kushko commented that "the Town continues to be proactive in
managing this problem". Penny is in and out of our parks throughout the day and will
gladly answer your questions should you see her or by calling the Public Works phone at
403-823-1330 and leaving a message. As well, please report any trees with the black
knot fungus on Town owned property to the Public Works number.
