Spot type net blotch caused by Pyrenophora teres f. maculata (Ptm) has become a prominent disease in Western Australia, as has also occurred elsewhere. The disease has a negative impact on both grain yield and quality resulting from reduced grain size. Lack of resistance and stubble retention are the likely factors in the increased severity of the disease(More)
Stagonospora nodorum blotch (SNB) is a significant disease in some wheat-growing regions of the world. Resistance in wheat to Stagonospora nodorum is complex, whereby genes for seedling, flag leaf, and glume resistance are independent. The aims of this study were to identify alternative genes for flag leaf resistance, to compare and contrast with known(More)
Rhynchosporium secalis can overcome a single resistance gene of barley in a relatively short period of time. Novel genes and quantitative trait locis (QTLs) are therefore vital to control scald in barley. A population of 220 double haploid lines was developed from a cross of Vlamingh and WABAR2147, where Vlamingh showed adult plant resistance (APR) and(More)
This work was done to demonstrate the opportunities provided by application of meta-analysis in plant pathology. It was a case study used to determine the effectiveness of foliar fungicides in minimising yield loss from a complex of yellow spot (Pyrenophora tritici-repentis) and septoria nodorum blotch (Stagonospora nodorum, teleomorph: Phaeosphaeria(More)
The Gauss–Seidel limb scattering (GSLS) radia-tive transfer (RT) model simulates the transfer of solar radiation through the atmosphere and is imbedded in the retrieval algorithm used to process data from the Ozone Mapping and Profiler Suite (OMPS) limb profiler (LP), which was launched on the Suomi NPP satellite in October 2011. A previous version of this(More)
Barley powdery mildew caused by Blumeria graminis f. sp. hordei is a most devastating disease in Western Australia and elsewhere. The disease has a negative impact on grain yield and quality and, thus, affects its marketability. The detection of pathogen variability has further impacted sustainable barley production. Various isolates have been reported to(More)
Perithecia carrying asci with mature ascospores were observed on millet stubble (Panicum miliaceum and Panicum sp.) and were identified as Gibberella zeae and Gibberella coronicola for the first time in Western Australia. Morphological identification and molecular assays confirmed the presence of the anamorph Fusarium graminearum and Fusarium(More)
