| USGA Summary Points: | Initial BDS symptoms appear between mid-May and early June and was greatest between late June and early August, but no new infection centers appeared after early October. The pathogen rapidly produces prodigious numbers of ascospores, which germinate in large numbers in the presence of leaves or roots within a few hours. Ascospores are the primary source of inoculum for secondary spread of the pathogen and they are dispersed by wind and water. During the winter months, the pathogen was most commonly isolated from creeping bentgrass crowns, stolons and roots and from overwintering psuedothecia. |
