Fruit fly treatment requirements for exporting mango fruit into South Australia, Tasmania and Western Australia
With the 2019 mango season underway, and in light of changes to some interstate quarantine requirements (relating to fruit fly) for mango exports last season, DPIR would like to remind mango growers/exporters that ICA accreditations will soon be due for renewal. A reminder letter will be sent in the near future. We would also like to take this opportunity to clarify the fruit fly treatments that are now permitted for the South Australian, Tasmanian and West Australian markets. A brief summary is provided below in Table 1.
It’s apparent that although these treatments are permitted they may not all be practical to implement, either because they require specialised apparatus (for example, heat treatment) or they are logistically not viable at the present time (for example, irradiation treatment).
CTM01, a systems approach negotiated trilaterally between the NT, Queensland and South Australia last season following South Australia’s unexpected suspension of ICA19, was subsequently accepted by Tasmania and Western Australia. Tasmania accepts CTM01 in its entirety (in lieu of ICA19 which they have suspended). However, Western Australia accepts CTM01 only where the post-harvest treatment option (that is, ICA01 or ICA02) is used. Western Australia does not accept the pre-harvest bait spray option in CTM01.
It is worth noting that Western Australia still accepts mangoes that have only been subject to post-harvest treatment with dimethoate (that is, ICA01 or ICA02). Therefore, ICA01 and ICA02 provide viable alternatives to CTM01 if all requirements of CTM01 cannot be met.
It also should be noted that previous requirements relating to securing consignments against fruit fly infestation during transit to these markets remain in place.
