Subject: First report of deadly wheat streak mosaic virus in Australia

After the discovery of wheat streak mosaic virus at two Commonwealth Scientific and Industrial Research Organization (CSIRO) facilities in Canberra, all potential host material was destroyed. These sites were placed under quarantine by the Australian Quarantine Inspection Service (AQIS) and an extensive program of surveillance and sampling was initiated. This virus, which is transmitted by the wheat curl leaf mite (Eriophyes tulipae), can cause total crop failure. Seed transmission is possible but occurs at very low levels. This is the first report of wheat streak mosaic virus in Australia. Globally it is prevalent in North America, Russia, and Eastern Europe.
