Subject: Phakopsora euvitis responsible for grapevine rust in Asia
Date posted: April 11, 2002

Recent taxonomic studies have revealed that the pathogen which causes grapevine rust in Asia is Phakopsora euvitis, and not P. ampelopsidis or P. vitis, which are restricted to other host plants (Ampelopsis spp. and Parthenocissus spp., respectively). This pathogen is found in east and southeast Asia, but in 2001 was detected in the Darwin area of Australia. The primary hosts are species of Vitis, mainly V. labrusca (fox grape) and V. vinifera (wine grape). Phakopsora euvitis is native to tropical and subtropical regions, and has been reported as more serious in these areas. The impact of this rust in temperate regions is poorly known, as is its status in North America. Grapevine leaf rusts have been recorded from the Americas, however, none appeared to be the two species mistaken for P. euvitis.
