The antifungal activity of B. subtilis against C. panacicola was observed on a co-culture medium. Interestingly,
treatment with B. subtilis did not significantly affect the diameter of the lesions, suggesting that
the mechanism of protection was through the reduction in the incidence of infection related to the initial
events of the infection cycle, including penetration and infection via spore germination and appressorium
formation rather than by the inhibition of invasive growth after infection
