Isolates of Rhizoctonia solani AG-10 have been collected at low frequency from wheat and barley roots in Washington and Oregon. In Western Australia, AG-10 is collected regularly, but at low frequency, from the roots of cereal, lupin and pasture species. In this study all attempts to induce AG-10 to sporulate were unsuccessful. However, earlier studies by(More)
The field symptoms of Eradu patch are distinct, stunted patches in narrow-leaf lupin and ill-thrift patches in barley. The pathogen, a thin, binucleate Rhizoctonia (TBR), is difficult to isolate with standard methods. To develop an assay specific to TBR, the ribosomal RNA ITS region was amplified and a 610 bp section including the conserved 5.8S region was(More)
Eradu patch is a relatively newly discovered disease causing distinct patches in narrow-leaf lupin and ill-thrift patches in barley. Because the field symptoms are similar to Rhizoctonia bare patch and the pathogen, a thin, binucleate Rhizoctonia (TBR), is difficult to isolate, it has been impractical to conduct incidence surveys. The development of a PCR(More)
It is with considerable pleasure that I write this short introduction to this 25th anniversary issue of our journal. In 1969 the first meeting of the then Australian Plant Pathology Society took place on Monday 18 August at the Waite Agricultural Research Institute, Adelaide. The meeting was held in a small lecture room and was attended by plant(More)
A survey of Pythium spp. from carrot-growing regions of Australia showed that P. sulcatum was the most common pathogenic species and occurred in all Australian states. It was isolated from carrots with a range of symptoms including cavity spot, and brown, discoloured, forked or hairy roots. Hordeum murinum P. violae was also isolated from tissue with cavity(More)
Transgenic tobacco plants expressing chitinase, ribosome-inhibiting protein or glucanase transgenes from barley, either singly or in combination, were tested for resistance to Rhizoctonia solani Kühn AG 4 and AG 8. With two exceptions out of 12 tests, the transgenic plants were resistant to AG 4 isolates, whereas only those plants showing high level(More)
Being the first son of a farmer, it was assumed by my parents and me that I would take over the family farm. Thus, it was planned that I should attend Muresk Agricultural College to gain an academic and practical grounding in farming. This plan changed, when in Year 9 at high school, the principal suggested to my parents and me that I should go to(More)
Former colleagues and friends "ill be saddened to hear of the recent death of Miss Olga Goss. Miss Goss, a former senior plant pathologist with the Western Australian Department of Agriculture, died in Perthon 13 March. Olga joined the Department in 1945 and became a highly respected plant pathologist. It is thought she was the first female university(More)
RAPD-PCRs were used to study 79 isolates of Rhizoctonia solani AG 8 representing four pectic isozyme groups [zymogram (ZG)] (ZG1-1, 1-2, 1-4 and 1-5) from various locations in southern Australia. RAPD-PCR was performed on all isolates using six primers and the relatedness of the isolates determined by generating a neighbour joining tree. All isolates were(More)
