COTINUS DISEASE PROBLEMS
Leaf spots can be caused by various genera of fungi but
are usually not serious.
Scab may cause leaf drop. No controls are listed for scab
caused by Venturia inequalis on this host.
The most serious disease is Verticillium wilt. Smoke tree
is very susceptible, and entire branches wilt and die.
Prune out infected branches, and fertilize and water the
plant during dry weather.
