Trichoderma as a biological control for Cytospora canker
Field and laboratory experiments were conducted to determine whether the fungus Trichoderma could be used as a protective control against Cytospora leucostoma infection on peach trees in Colorado. Wounds treated with Trichoderma had less infection than the controls. T. aureoviride was the only significantly effective one of the four Trichoderma species tested. The action of Trichoderma against Cytospora may be attributed in part to direct hyphal antagonism and to a possible production of a diffusible antibiotic.
