Subject: Re: [CANUFNET] CANUFNET Digest, Vol 62, Issue 6
I need some good information on the importance of hedgerows in an eco
system. Can anyone point me to some good information that comments on
wildlife, insects, small trees and bushes and their interrelationship with
large trees, farmland etc.?

> For the past few years the City of Edmonton has been experiencing an
outbreak of black knot (Apiosporina morbosa). Edmonton's urban forestry
unit, River Valley Forestry and Environmental Services (RVFES) has been
responding by pruning out the visible fruiting bodies, and by removing trees
that are beyond saving. However, if we continue these practices we will
eventually end up removing thousands of our valuable ornamental trees of the
genus Prunus. So, we are asking other municipalities about their experience
with this fungal pathogen and what steps they have taken to battle black
knot. RVFES would greatly appreciate if you could aid us in our fight
against black knot by taking the time to answer the following questions.
>
> * Does your region have problems with black knot? If so do you have a
campaign or strategy for combating it? If yes, how do you communicate your
strategy to the public, and what do you do to encourage citizens to take
care of black knot on their own trees?
> * If your municipality does treat for black knot, what treatments were and
were not successful?
> * How serious is black knot mortality in your municipality?
> * Aside from Amur cherry, do you know of any black knot resistant
varieties? Have you had success with any of these varieties?
> * How does your municipality dispose of infected material?
> * Has your municipality tried or had any success with the biological
control agent, Trichothecium roseum (fungal parasite)?
