Berl. and de Toni. Following the foliar inoculation of plants with conidial suspensions of selected B. bassiana strains, colonization of leaves by the fungus was determined using culture-based and PCR techniques at different time intervals. Seven days following B. bassiana inoculation, grapevine plants were challenged with P. viticola and symptoms were assessed by calculating the disease incidence and severity. Although all tested strains were able to colonize grapevine plants, percent colonization differed significantly among strains. Disease incidence and severity were, on the other hand, significantly reduced in B. bassiana-inoculated plants compared to control plants irrespective of strain. This study is one of very few studies investigating the promising role B. bassiana could play as a plant disease antagonist.
