| Abstract/Contents: | "Dallas area landscapes were severely affected by an extended period of drought during the hot summer months of 1980. Unusually high temperatures and a virtual absence of rainfall during the summer were particularly damaging to established St. Augustinegrass lawns maintained under restricted water use programs. Large areas of poorly developed and dying St. augustinegrass on residential landscapes were observed from June to Septemer. Field studies of St. Augustinegrass homelawns indicated a common occurrence of a stolon die-back condition associated with dark brown to black lesions on stolon internodes recovered from declining areas of turf. Laboratory observations and isolations from infected stolons associated severe disease activity with a fungus identified as Nigrospora spp. Inoculation studies demonstrated pathogenicity of the fungus on stolon internodes. Disease activity by the fungus contributed to poor development and die-back of St. Augustinegrass stolons during the hot summer months." |
