Yellow dwarf of tobacco in Australia. V. Transmission by <i>Orosius argentatus</i> (Evans) to some alternative host plants.

Abstract

Tobacco yellow dwarf virus disease was experimentally transmitted to 15 species of plants by the leafhopper, Orosius argentatus (Evans). Eight of these plants are summer annuals and seven are autumn-spring growing plants which provide a continuous succession and wide range of hosts. Their occurrence in the districts where tobacco is grown makes control by the elimination of alternative host plants appear impracticable.
