Survival and growth of selected trees is an
important aspect of forest management. Weeds compete with these
trees for light, moisture, nutrients and space.
To examine the possibility of using a fungus
to control forest weeds.
- Evaluate the efficacy of a fungus (Chondrostereum purpureum)
on red maple and speckled alder stump sprouting.
- Compare the degree of efficacy of the fungus relative to conventional
chemical herbicide treatment.
Weed management alternatives included in this
research project:
- Control: Cut weeds with no additional treatments.
- Fungus: Cut weeds and apply fungus (Chondrostereum purpureum)
- Herbicide: Cut weeds and apply conventional herbicide treatment
(triclopyr).
- Fungus exhibited greater efficacy
on speckled alder as compared to red maple.
- Conventional cut-stump treatment
with herbicide (triclopyr) provided better efficacy than the fungus
on both red maple and speckled alder.
- Where herbicide use is restricted
or socially unacceptable, C. purpureum may offer a viable alternative.
Additional research is required for
the use of biological control of woody vegetation.
