Treatment has promise against Dutch elm disease
Treatment has promise against Dutch elm disease Most of Canada's elm trees have been killed over
the years by the tiny bark beetle, which carries a fungus that
infects the tree. Recently, however, a pathologist in Toronto has
discovered a non-toxic compound that may save the trees. This is
extremely good news for places like Winnipeg, Saskatoon and Regina,
where the tree is one of few that can survive the harsh winters and
provide large amounts of shade in the summers. The compound would
be injected into elm trees and would stimulate the tree's own
natural immune system. 8 JANUARY 1999
