Previous detections of Fusarium mangiferae include: - November, 2007 at the Coastal Plains Research Station (CPRS), about 60 kilometres east of Darwin, Northern Territory (NT). This fungus has not been previously detected in Australia. CPRS was quarantined and the mango trees removed and destroyed. - December, 2008 at Bellemere, Queensland. Four infected trees that were part of private collection that had been imported were identified and destroyed. No further infected trees have been identified in Queensland and the fungus is considered to be no longer present. Between 2009 and 2012 seven infected trees were identified across three additional premises in NT during ongoing surveillance subsequent to CPRS. Further surveillance and monitoring has been undertaken to determine if Fusarium mangiferae is still present in the NT and to consider the feasibility of eradication. No further detections of the fungus have been made since 2012. It is thought the fungus may have been present in NT for several decades and measures are in place to regulate mango nursery stock and propagation stock movement to other states and territories. During this period of heightened awareness to F. mangiferae, other species of fusariums that cause symptoms identical to MMD were also detected.

Mango Malformation Disease (MMD) is a fungal disease of mangoes caused by several species of Fusarium. It affects tree growth and is not spread or carried on fruit. Mangoes are the only known host of the disease. It has been found in many overseas mango producing countries. In other countries, F. mangiferae is reported to cause severe symptoms on susceptible hosts with significant yield loss. During the 10 years that F. mangiferae has been known to occur in Australia, there has been no evidence of adverse economic impact regionally or nationally. Since it is not a fruit borne disease, the detection of F. mangiferae in the NT will not affect the transport of fruit within NT, interstate or overseas markets.
