The occurrence of “wasting disease” of Zostera in Ireland in the 1930's

Abstract There is only one publication quoted in connection with “wasting disease” of Zostera marina L. in Ireland. This was examined and it was concluded that in fact, it did not describe “wasting disease”, but merely the normal seasonal changes of Zostera . However, another report which has not been quoted before did give an account of the disease in County Down. Evidence that the disease occurred in County Mayo is presented for the first time.
