Diseases caused by Tobacco streak virus (TSV) have resulted in significant crop losses in sunflower and mung bean crops in Australia. Two genetically distinct strains from central Queensland, TSV-parthenium and TSV-crownbeard, have been previously described. They share only 81% total-genome...

A new distribution map is provided for Beet mosaic virus. Potyviridae: Potyvirus. Hosts: beetroot (Beta vulgaris), sugarbeet (Beta vulgaris var. saccharifera) and white yam (Dioscorea alata). Information is given on the geographical distribution in Europe (Albania, Austria, Belgium, Bulgaria,...

Recent laboratory studies have demonstrated that Prunus necrotic ringspot virus (PNRSV) can be readily transmitted when thrips and virus-bearing pollen are placed together onto test plants. For this transmission mechanism to result in stonefruit tree infection in the field, PNRSV-bearing pollen...

In late 1994, bushfires in the Beerburrum area north of Brisbane, in Queensland, Australia, damaged 8688 ha of pine plantations (mostly Pinus elliottii, P. caribaea and P. taeda). In the 4712 ha of government-owned plantations affected, large-scale salvage operations were commenced quickly in order ...

In September and November 1994, wildfires caused damage to 9 thousand hectares of slash pine (Pinus elliottii var. elliottii) in plantations near Beerburrum, SE Queensland. During the salvage operation sapstain and decay were monitored by periodically felling and sectioning trees in five plots in...

Incidence of tobacco streak ilarvirus (TSV) in an Australian (Queensland) tobacco crop at flowering was shown by ELISA to be 58-59% in outside rows near weeds infected with TSV, decreasing to 10-18% in the 12th row inside the crop. The most prevalent dicotyledonous weed, A. houstonianum, had a 50%...
