LAST year’s detection of grapevine red blotch virus remains an open incident while the situation is being assessed.
The first vines infected with GRBV are believed to have arrived in Australia in 1969, or earlier, and there are now several wine and table grape variety clone combinations that have tested positive in Victoria and South Australia.
The virus has caused significant economic damage in vineyards in parts of the US, however in Australia it is thought to be isolated to specific variety clone combinations.
