Abstract
Currently propagating material of all fire blight hosts imported to Australia are kept under quarantine observation for two years in the glasshouse and one year outside before the material is released to the importer.
As this procedure is considered unsatisfactory for several reasons the following new procedure has been proposed.
All propagating wood will be imported only from approved sources, and should have originated from properties which were free of fire blight during the current season and the previous season.
On arrival they will be examined for fire blight, and if free, will be disinfected and either budded or grafted.
New growth will be inspected for disease, and the proximal portion of it removed and further checked on a modified nutrient sucrose agar medium for Erwinia amylovora; any resulting bacterial growth will be tested serologically and by the pear fruitlet test.
If it is found free of E. amylovora, the distal portion of new growth will be released to the importer.
