Wheat streak mosaic virus and wheat curl mite and their management
No full textWheat streak mosaic virus (WSMV) is a seed and mite-borne virus that infects wheat, causing severe leaf symptoms and reduced yields. The symptoms and damage are more severe in wheat than other hosts, in which infection is symptomless.
Wheat streak mosaic virus can cause crop failure when widespread infection occurs in seedling wheat, particularly when a heavily WSMV-infected green bridge is not controlled before sowing an early crop, and warm temperatures favour mites.
Wheat curl mite (Aceria tosichella) is the only known vector of WSMV. It can transmit the virus in its nymph and adult stages
Strategic deep tillage and crop rotation for improving productivity of non-sodic heavy soil in the low rainfall regions of Western Australia
No full textNon-sodic heavy soil in the low rainfall regions of Western Australia can be dense and poorly structured with alkaline clay in the subsoil, which prevents root exploration and potentially restricts grain yield. A 4-year long (2020-2023) field experiment was established near Bencubbin in 2020 to investigate whether the loosening of dense soil layers with a strategic deep ripping followed by a summer crop, super sweet sudan (SSS) forage sorghum and crop species of varying root architecture (barley, canola, chickpea, and vetch+oat), or fallow in 2021 can increase barley root exploration in the subsurface soil layers and yield in subsequent years (2022 and 2023). The results showed that deep ripping and SSS had no significant impact on barley grain yield in 2021, 2022 and 2023 compared to no ripping and without SSS. Barley grain yield in 2022 was significantly increased following fallow, chickpea and canola compared to following vetch+oat and continuous barley. In 2023, barley grain yield showed no significant difference due to extremely dry conditions. We concluded that deep ripping in this dense, non-sodic, heavy soil might have limited benefit on crop root exploration or yield. Summer crops such as SSS could be grown to fill the feed gap for grazing without significantly affecting the yield of the crops in the following years. Keeping the land fallow or growing break crops (e.g. canola/chickpea) might be beneficial for increasing cereal crop yield compared to continuous barley
Fer wine grapes in Western Australia
No full textFer is a French variety known to produce concentrated wines of good colour with a medium to full body. Wine aroma and flavour are typified by dark fruits and spice with soft tannins.
Fer grapevines were evaluated for fruit and wine production in Manjimup from 2007 to 2010.
Fer was found to be late ripening when grown here although it showed good disease resistance
Can the necrophagous blow fly Calliphora vicina (Diptera: Calliphoridae) be reared on plant-based meal?
No full textThe use of the blow fly Calliphora vicina as a potential pollination species to augment the current reliance on honeybees (Apis mellifera) in Australian horticulture requires knowledge of how best to mass-rear this fly species. Calliphora vicina lays eggs onto carrion soon after death, and the resultant larvae that hatch are necrophagous and feed on the decomposing tissues of the dead animal. Newly hatched larvae of this fly were provided with plant-based meals (soya bean and canola) and compared with larvae provided with livestock-derived meatmeal to determine if plant-based meal could be used to mass-rear this blow fly species. Both soya bean and canola meal media did not support larval survival through to adult emergence. The addition of only 10% whole egg powder to the plant-based meals enabled survival to eclosion of 39% and 13% on soya bean and canola-based media, respectively, compared with 76% on livestock-based meatmeal with 10% whole egg powder. Larvae fed a diet of livestock-based meatmeal with 10% whole dried egg powder had the fastest development to the pupal stage, the highest pupation rate, the heaviest pupae, and the highest subsequent adult eclosion. This study concluded that the use of plant-based meals as a diet for the mass-rearing of the blow fly C. vicina was not a viable option
Strategies for productivity, profitability, and greenhouse gas mitigation - a Western Australian perspective
No full textThis paper presents new estimates of greenhouse gas (GHG) emissions from six of Western Australia’s (WA) agricultural industries, including pre-farm emissions from the manufacture of inputs such as fertilisers, chemicals and purchased feed. Total on-farm and pre-farm emissions are estimated to have been about 14.5– 15.2 megatonnes of carbon dioxide equivalents (Mt CO2e) per annum (p.a.) from 2019-20 to 2021-22. Emissions originated largely in the beef (5.3–5.6 Mt CO2e p.a.), grains (4.4–5.1 Mt CO2e p.a.) and sheep (3.8–4.0 Mt CO2e p.a.) industries. Methane from enteric fermentation accounted for about 45 % of estimated total emissions, with some indication that this share may be decreasing over time through lower livestock numbers and increasing grain production. As grain yields increase, pre-farm emissions will be increasingly important to the WA agriculture sector’s mitigation efforts. WA studies suggest that strategies exist that can improve the efficiency and profitability of agricultural businesses while delivering mitigation co-benefits

The Changing Retail & Consumer Landscape
No full textGrocery retailing is facing unprecedented challenges driven by a convergence of factors throughout the value chain. The pandemic spurred innovation and permanently altered consumer behaviours, now dealing with rising inflation and tightening discretionary spending. This presents both challenges and opportunities for retailers, producers and supply chain stakeholders.
Sustainability remains a priority for consumers and retailers, but both are hesitant to bear the associated costs. Effectively communicating sustainability efforts and leveraging retailer networks are crucial to build scale and extend reach to consumers, along with developing economically viable solutions.
Additionally, it\u27s vital to recognize the necessary skills for engaging with retailers effectively, particularly from a sustainability perspective. This includes understanding how to navigate sustainability discussions within retail partnerships and aligning sustainability goals with broader business objectives.
Tristan Kitchener, an ex-retailer and an expert in grocery retailing and consumer trends, offers insights into the future trajectory and growth prospects for retailers and producers. As businesses strive to address consumer pain-points and adapt to evolving retailers standards, those that proactively embrace sustainability initiatives will likely emerge as frontrunners in driving growth
Puerulus settlement forecasting in a harvest strategy evaluation of the rock lobster fishery in South Australia
No full textHarvest strategies are utilised in the management of fishery resources globally. Critical to their success is harvest strategy evaluation, whereby future performance is assessed through projection modelling. Using the observed relationship between a puerulus settlement index and model-estimated recruitment, we evaluated a southern rock lobster (Jasus edwardsii) harvest strategy in South Australia. Short-to-medium puerulus settlement recruitment forecasting was incorporated into future projections of catch, catch per unit effort, and percent unexploited egg production (%UEP) during 2019–2022. Observed values of indicators that closely aligned with projected outputs indicated that puerulus forecasting underpinned reliable evaluation of future fishery performance. A key objective of the harvest strategy was to increase egg production in the fishery, with a 20% unexploited egg production targeted by 2036. The target was reached under the proposed strategy, but was sensitive to recruitment, thereby highlighting the need to consider climate change impacts in forecasting scenarios
