Abstract
The mycoherbicide of the present invention is effective in the control of Calamagrostis canadensis and/or related grasses, particularly in areas undergoing reforestation. The mycoherbicide includes one or both of Fusarium nivalis (ATCC #26050) and a fungus, Colletotrichum calamagrostidis (PFC-215, ATCC #74287), isolated from a diseased plant of C. canadensis var. canadensis. The mycoherbicidal formulation preferably includes an allelopathic agent, such as straw, straw-based material, straw extract, grass extract or an endophyte. An especially effective treatment was demonstrated with C. calamagrostidis (PFC-215) and an inoculum of endophytic Fusarium nivalis. An embodiment of a method of treatment according to the present invention includes the application of endophytes of reduced virulence to grass bordering a target area or in grazing lands, to prevent either natural or inoculative infection.
