Doubling water-limited yield potential by reengineering sands and texture contrast soil in Western Australia
No full textWhile grain yield increased significantly due to soil amelioration, the gap between the theoretical and actual yield potentials remains substantial in Western Australia (WA). Soil reengineering (building ideal soil profiles) might remove all interacting soil constraints and maximise uptake of subsoil water and nutrients. Therefore, true yield potential will be determined for various crops, soil types, and environments
Wheat blast: emerging future disease threat of wheat in South Asia and Australia
No full textWheat blast (WB) caused by the fungus Magnaporthe oryzae Triticum (MoT) lineage (synonym Pyricularia oryzae Triticum) is one of the potential future disease threats to the wheat industry in Asia and Australia. This paper is designed to create awareness among growers, professionals, and researchers about WB disease and its potential risk to wheat production systems in Australia

Fisheries science update - Pilbara Demersal Scalefish Resource - November 2023
No full textKey points: 2023 stock assessment outcomes: The Pilbara Demersal Scalefish Resource (PDSR) spans from the North West Cape to 120ºE and comprises over 60 demersal scalefish species, including indicator species red emperor, rankin cod, and bluespotted emperor. The PDSR is accessed by recreational fishers, charter operators and three commercial fisheries: Pilbara Fish Trawl (Interim) Managed Fishery, Pilbara Trap Managed Fishery, and the Pilbara Line Fishery. The PDSR is a key ‘food bowl’ for Western Australia, supplying the local market with about 2,500 tonnes of demersal scalefish annually. The PDSR provides unique and valuable recreational fishing opportunities at locations such as the Montebello and Mackerel Islands, and the Dampier Archipelago. The status of the PDSR is assessed by the Department of Primary Industries and Regional Development (DPIRD) via weight of evidence stock assessments undertaken every 3 to 5 years. The assessment of red emperor in the Pilbara region is the most comprehensive finfish assessment in WA due to an extensive timeseries of catch and biological data. The 2023 stock assessment shows that there are significant sustainability concerns for red emperor and goldband snapper and management action is required to reduce fishing pressure and begin recovery
Gouldian Finch Monitoring: Foraging Activity and Grass Phenology - Goomig Project 2022 to 2023
No full textThe Goomig Project (Weaber Plains Development Project) is an irrigated agricultural development located approximately 30 km north of Kununurra, which involves clearing of approximately 9,260 ha of vegetation for agriculture. Approximately 11,470 ha of native vegetation surrounding, or remaining between, the cleared areas is designated as a buffer area (the study area) to be managed to protect surrounding conservation reserves and watercourses (Strategen 2014). Monitoring of Gouldian Finch wet season foraging activity and phenology and productivity of grasses important for foraging in the buffer area during ongoing operation are required as conditions of the approval for the project, and is outlined in the Gouldian Finch Conservation Plan (GFCP; Strategen 2014).
Item 8 of the monitoring regime requires “annual wet-season monitoring of foraging activity in critical wet-season feeding areas in close proximity to breeding areas, to be undertaken between November and April each year”, and Item 9 requires “mapping and annual monitoring of the phenology and productivity of wet season feeding habitat, and assessment of their use by Gouldian Finches, to be undertaken between November and April each year”
Profitable low-emission crop rotations?
No full textIn some southern WA grainbelt regions it is feasible to alter crop rotation selection while maintaining farm profitability and reducing agricultural GHG emissions. In the northern WA grainbelt, shifting into crop-based rotations increases profitability while decreasing agricultural GHG emissions. Research and innovation in low-emission fertilisers and anti-methanogenic feeds or pastures will help further reduce agricultural emissions

WA Insecticide Guide 2023 - Winter Spring
No full textRegistered chemicals for broadacre crops in Western Australia.
The insecticides listed in the tables within this guide can be used on any crop appearing on the chemical label, if the rate used does not exceed the highest rate that is registered for use on that crop.
There are many products with different trade names that contain the same active ingredient. This list is not exhaustive and does not imply any specific recommendations of brand names.
Unless otherwise specified all insecticides listed are emulsifiable concentrate (EC). Insecticides with SC are suspension concentrate, WP is wettable powder, CS is capsule suspension, WG are wettable granules (water dispersible granules), EW is emulsion and DF or WDG is dry flowable or water dispersible granules. Ultra-low volume (ULV) insecticides are not listed.
Read the chemical label before use and check label withholding periods for grazing or hay/silage/fodder production before application.
Please turn on punctuation if using a screen reader.
