Seedbed inspections underestimate the overall incidence of ratoon stunting disease* [Full subscriber]

Abstract In Australia, only prospective seedbeds are routinely screened for ratoon stunting disease (RSD). As seedbeds may reasonably be considered to be the healthiest cane available to a grower, it may be expected that there would be a higher incidence of RSD in commercial fields.
