Abstract
The most serious foliar disease of eucalypt plantations in WA is Mycosphaerella leaf disease (MLD) (1). Since the commencement of the plantation industry, several fungal species contributing to MLD, previously known only in eastern Australia or overseas, have been reported on E. globulus in WA. Initially only three species were identified (2). More recently, five new records from WA (M. aurantia, M. ellipsoidea, M. mexicana and M. fori) have been identified that have not been recorded elsewhere in Australia (1, 3). Currently, 13 species of Mycosphaerella have been recorded in WA from Eucalyptus (3). Re‐examination of cultures adds six new species that have yet to be described from E. globulus in WA. The impact of MLD on growth of E. globulus plantations in WA was examined in a chemical exclusion trial at two plantations in the Albany region.
