Rhynchosporium causes scald-like lesions on leaves, with early symptoms generally appearing as pale green oval lesions. As the lesions age they acquire a dark brown margin, with the centre of the lesion remaining pale green or pale brown. Lesions often coalesce forming large areas around which leaf yellowing is very common. Infection often occurs in the leaf axil which can cause chlorosis and eventual death of the rest of the leaf.
