An investigation by Agriculture Western Australia in association with the viticulture industry has concluded that no serious viruses were found in a Great Southern vineyard. A six week investigation was initiated after a grower reported a bright yellowing of leaves on several vines. Plant material was sent to interstate and overseas laboratories for testing. Agriculture WA principal research officer Tony Devitt said the results showed the presence of two viruses, however neither pose a threat to the industry in isolation - as has occurred in this instance. Vines containing these viruses are accepted by the industry, according to Australian Vine Improvement Association's policy on vine material accredited for distribution.
