Ergot: A New Disease Threat to Sorghum in the Americas and Australia.
TLDR
The most significant technological change since the 1960s has been the development and use of F1 hybrid seed, which has lead to a dramatic improvement in the crop’s productivity.
Cercospora traversiana on fenugreek (Trigonella foenum-graecum) in Queensland

    Australasian Plant Pathology
  • 1 September 1989
TLDR
Cercospora traversiana was isolated from 25.3% of darkcoloured fenugreek seed harvested from a crop in southern Queensland and caused rapidly expanding lesions on all above-ground parts and a darkening of seeds.
Soybean Diseases of the North Central Region

  • Biology
    Australasian Plant Pathology
  • 2011
TLDR
This publication is based on the proceedings of the North Central Region Soybean Disease Workshop held in Indianapolis, Indiana in early 1987 and contains 20 papers which have been written by 21 authors and is likely to be the most comprehensive reference source up to 1988 for many of the diseases.
Fungal diseases of temperate annual pasture legumes in southern Queensland
TLDR
Improved knowledge of diseases of temperate annual legumes in southern Queensland will assist in the future selection and breeding of suitable cultivars for use in the subtropics.
Changes in the Racial Composition of Phytophthora sojae in Australia Between 1979 and 1996.
TLDR
Only races 1 and 15 have been found in the northern soybean-growing regions, with the latter dominating, which coincides with the widespread use of cultivars with the Rps2 gene.
The evolution of races of Phytophthora sojae in Australia
TLDR
The low levels of genotypic diversity observed in Australian fl sojae populations compared to the high level observed in the U.S. population indicates that the Australian population was most likely established by a single introduction of the pathogen.
Phylogenetic relationships of graminicolous downy mildews based on cox2 sequence data.
TLDR
A first molecular phylogeny based on cox2 sequences comprising all genera of the GDM currently accepted, with both lasting (Graminivora, Poakatesthia, and Viennotia) and evanescent (Peronosclerospora, Sclerophthora, and SclerOSpora) sporangiophores is presented.
Identity and genetic diversity of the sorghum ergot pathogen in Australia
TLDR
It is confirmed that ergot of sorghum in Australia is caused by C. africana and the genetic diversity among isolates of the ergot pathogen from Australia and overseas is unexpected.
Sorghum ergot (Claviceps africana) associated with agalactia and feed refusal in pigs and dairy cattle.
TLDR
Clinical, pathological, toxicological and epidemiological examination of clinical cases in 10 piggeries and 4 dairies establish the main clinical features of a syndrome characterised by severe feed refusal, death of piglets and reduced milk production in pigs and dairy cattle.
Alkaloids of the sorghum ergot pathogen (Claviceps africana): assay methods for grain and feed and variation between sclerotia/sphacelia
TLDR
Within batches, there was much less variation in the alkaloid content of ergot bodies, but larger ergots tended to contain more alkaloids than smaller ergots, and those infected with Cerebella species contained even less; this probably related to the ratio of sclerotial/sphacelial tissue present.
