N2  - A witches' broom condition of lucerne, characterized by foliage symptoms similar to those attributed to a leafhopper-transmitted virus, is described. The lucerne bud mite, Aceria medicaginis Keifer, has been found to be consistently associated with affected plants collected in a number of localities in northern Victoria. Mites transferred to healthy lucerne seedlings induced the leaf and foliage proliferation symptoms observed on field-collected plants. Experimentally and naturally affected plants recovered when sprayed with thiometon, which indicated that the mite was not acting as the vector of a virus. This previously unreported association of eriophyid mites with witches' broom of lucerne is discussed in relation to findings from earlier aetiological and ecological studies on the disease in Australia.
