Virulence Assessment Of Australian Pyrenophora Tritici-Repentis Isolates, Pao Theen See, Kefei Chen, Kalai A. Marathamuthu, Nikki Schultz, Manisha Shankar, Caroline S. Moffat

Biosecurity Research Articles

The virulence of 57 Australian isolates of Pyrenophora tritici-repentis (Ptr), a necrotrophic fungal pathogen responsible for the major wheat disease tan spot, was assessed through plant infection assays. Isolates collected from the northern, southern, and western wheat-cropping regions of Australia were evaluated against 16 Australian bread wheat cultivars under controlled growth conditions. Following infection, the wheat panel displayed varying disease symptoms ranging from tiny necrotic specks to spreading chlorotic and necrotic lesions. Analysis of variance indicated that the wheat cultivar exhibited a greater effect on the disease response, explaining 62.7% of the variation, in comparison to the isolate …

Native And Non-Native Sources Of Carbohydrate Correlate With Abundance Of An Invasive Ant, Lori Lach, Benjamin Hoffmann, Melinda L. Moir

Biosecurity Research Articles

Invasive species threaten many ecological communities and predicting which communities and sites are invasible remains a key goal of invasion ecology. Although invasive ants often reach high abundances in association with plant-based carbohydrate resources, the source and provenance of these resources are rarely investigated. We characterized carbohydrate resources across ten sites with a range of yellow crazy ant abundance in Arnhem Land, Australia and New Caledonia to determine whether yellow crazy ant (Anoplolepis gracilipes) abundance and trophic position correlate with carbohydrate availability, as well as the relative importance of native and non-native sources of carbohydrates to ant diet. …

Plant Diseases Impacting Oaten Hay Production In Australia - A Review, Kylie Chambers, Geoff J. Thomas

Bulletins 4000 -

In Australia, there are a range of fungal, bacterial and viral pathogens that infect oats, impacting on yield and quality of grain and hay crops. The overall impact of these diseases on oaten hay production is not well researched or understood, especially compared to that of other cereal crops. Export hay is evaluated on physical qualities such as stem thickness and greenness and nutritional qualities including water-soluble carbohydrates, neutral detergent fibre, acid detergent fibre and dry matter digestibility. The colour/ greenness of oaten hay can be reduced by disease lesions, chlorosis and saphrophytic fungi growing on dead tissue all of …

Bedstraw Eradication Program 2019/2020 - Annual Report To Grain Growers, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity published reports

Three-horned bedstraw (Galium tricornutum) is a competitive weed that can cause considerable yield loss in crops, and its seeds are contaminants of fodder and grain. The presence of bedstraw requires infested areas to be quarantined whilst a nine-year program is undertaken – six years of herbicide treatments followed by a three-year ‘release phase’.

In 2019/20 the Program reached a major milestone with quarantine restrictions fully lifted from one property and lifted from the arable areas of a second property. This is a major step toward eradicating bedstraw from Western Australia.

Skeleton Weed Program 2019/2020: Annual Report To Grain Growers, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity published reports

2019/20 saw the Skeleton Weed Program expand its surveillance and control activities, with financial support from the IFS, specifically:

- Landholder incentives for paddock surveillance were increased and made available for surveillance undertaken on reinfested ‘Code 2’ paddocks. These changes were anticipated to enhance the level of surveillance for skeleton weed, enabling plants to be identified and treated and, therefore, reducing the risk of seed-set and spread.

- The IFS covered the cost of chemical for winter spraying undertaken on heavily infested paddocks. It was anticipated that this would help landholders reduce the level of skeleton weed infestation and, in …
