Indexing for grapevine virus diseases in Australia has shown that many vines contain multiple graft-transmissible diseases and that a common combination is leafroll plus yellow speckle.
These two diseases are present in all our high yielding selections of Sultana but the economic importance of the complex is not known.
This paper reports an assessment of the combined infection when experimentally introduced into Cabernet Franc.
This wine cultivar, grown widely in France, is now attracting interest in Australia.
Because there is no information on the training of Cabernet Franc in Australian irrigated environments, and to test a possible interaction between virus and pruning system, two pruning treatments, spur and cane-pruned, were included.
