It has been reported at the Seventeenth Session of the Asia and Pacific Plant Protection Commission (APPPC) that Xanthomonas campestris pv.citri (EPPO A1 organism) has been detected in an isolated citrus orchard in the Northern Territory of Australia in April 1991. Infected trees were removed and the area is quarantined. Previously, it was thought that citrus canker had been eradicated from the Northern Territory.
It was further reported that the orange stem pitting strain of citrus tristeza closterovirus has been detected in Queensland 1990. The area concerned has been quarantined to restrict spread to other states in Australia.
