The experiment in which the T. atroviride SC1-treated bark mixture was applied as mulch to strawberry plants in the presence of A. gallica inoculum yielded positive results in term of A. gallica control. Three months after pathogen inoculation, most of the A. gallica control plants had withered leaves, with white mycelia and rhizomorphs inside and around the rotted roots and crowns and/or dead. The disease incidence in the A. gallica control was
70 ± 1.4% (mean of 40 plants ± SE), which was significantly higher (p < 0.05) than the incidence of disease on strawberry plants mulched with bark that had been pre-treated with T. atroviride SC1 (25 ± 2.3%). In all of the pots containing infected plants, the rhizomorphs of the pathogen were observed in both the bark mulch layer and the underlying peat. A. gallica was never observed on untreated (control) plants.
