Tilletia indica not found in Alabama and Tennessee
As reported in EPPO RS 98/043, it has been concluded that Tilletia indica (EPPO A1 quarantine pest) is not present in Alabama and Tennessee (US). These records are now considered as misidentifications with another fungi causing ryegrass bunt which has been identified as a new species Tilletia walkeri. This fungi causes a partial bunt on Lolium perenne and L. multiflorum. An extensive survey of Lolium multiflorum in wheat fields was conducted in spring 1997 and 1998 in Georgia, as well as in Alabama and Tennessee. The survey showed that T. walkeri is widely present in these States but at very low levels. No teliospores of T. indica were found during the survey.
