The health status of most of the commercially available finger lime cultivars is largely unknown as they have not been tested by the Australian Citrus Propagation Association Incorporated (Auscitrus). Auscitrus budwood trees are regularly tested to ensure freedom from exocortis, psorosis and other graft transmissible pathogens. Currently Auscitrus maintains mother trees of Citrus australasica var. sanguinea ‘Rainforest Pearl’ as well as the cultivars C. australasica ‘D1’ and ‘Ruby’ in their insect proof repository.
