Lychees

Australian Lychee Growers Association are members of Plant Health Australia and signatories to the Emergency Plant Pest Response Deed. Their responsibilities include:

  • biosecurity planning and implementation at the national and farm levels
  • liaising with federal and state governments on trade issues
  • funding and supporting biosecurity initiatives
  • participating in national committees and response efforts in an emergency.

Industry overview

In 2017–18, lychee production of 2,733 tonnes was valued at $24 million (LVP), with 466 tonnes exported valued at $5.2 million.

Higher volumes of lychee exports occur during the lead up to the Chinese New Year. Kwai Mai Pink is the preferred export variety due to availability, taste, quality and price. Salathiel, with a good flesh to seed ratio, is in high demand in Singapore and yields good returns for growers willing to persist with this variety. Exports of Australian lychees to the United States are increasing each year, with 10 tonnes exported in the 2018–19 season. This figure is expected to double in the 2019–20 season.

The new Chinese varieties of Chompogo, Erdon Lee and Baitangying are now appearing in the domestic markets: even though quantities are small, these varieties will continue to increase as current plantings mature.

Following the 2016 signing of the memorandum of understanding between the Australian Department of Agriculture and Taiwan Agriculture Research Institute, six Taiwanese lychee varieties have now been planted on an orchard in central Queensland. This is a long-term project, as it will be a number of years before Taiwan is able to apply for Plant Breeder’s Rights for these new varieties.

Lychees are produced as a single annual crop with the harvest period from late October (north Queensland) to March (northern NSW). This gives the Australian lychee season one of the world’s longest production period, as well as a counter-seasonal supply to most other lychee producing countries.

Industry Biosecurity Plan for the Lychee Industry

Biosecurity planning provides a mechanism for the lychee industry, government and other relevant stakeholders to assess current biosecurity practices and future biosecurity needs. Planning identifies procedures that can be put in place to reduce the chance of pests reaching our borders or minimise the impact if a pest incursion occurs.

The Industry Biosecurity Plan for the Lychee Industry outlines key threats to the industry, risk mitigation plans, identification and categorisation of exotic pests and contingency plans. For a copy, please contact PHA on 02 6215 7700 or email [email protected].

Exotic pests (not in Australia)

The following is a list of high priority exotic pests of lychees. These pests were identified during the development of the Industry Biosecurity Plan for the Lychee Industry in consultation with industry, government and scientists. They have been assessed as high priority pests based on their potential to enter, establish, and spread in Australia (eg environmental factors, host range, vectors) and the cost to industry of control measures.

PHA has a range of fact sheets, contingency plans and diagnostic protocols relevant to these pests. Pest risk review documents are also available for some pests. Please contact PHA on 02 6215 7700 or email [email protected] for more information.

Endorsed National Diagnostic Protocols are available from the National Plant Biosecurity Diagnostic Network webpage.
