Funji associated with diseases of forest weed species were tested for their mycoherbicide potential under greenhouse, growth chamber and field conditions. Several field treatments were applied, and subsequent changes to competing vegetation were measured in terms of foliar disease ratings and % cover estimates. Treatments which have shown positive responses are: hardwood overstory removal (resulting in mortality of aspen stumps); defoliation of thimbleberry (increased foliar disease rating in the subsequent year); foliar inoculation with Septoria rubi (increased disease ratings of thimbleberry in the current year); 1.6 kg/ha glyphosate (some foliar damage to thimbleberry). Biological control using mycoheribicides is seen as a potential alternative to present methods, and also offers numerous ways of improving the efficacy and safety of conventional vegetation management strategies.
