Bedstraw Eradication Program 2024-25: Annual report to grain growers
No full textThe Bedstraw Eradication Program operates under the Biosecurity and Agricultural Management Industry Funding Scheme (Grains) Regulations 2010.
Approved Plans developed annually for each infested property in consultation with the Grains, Seeds and Hay Industry Management Committee (GSHIMC), the Department of Primary Industries and Regional Development (DPIRD) and the landholders detail management actions, estimated costs and timeframes of agreed actions
Fisheries Research Report No. 353: Ecological Risk Assessment for the North Coast Demersal Scalefish Resource
No full textOn the 26 March 2025, the Department of Primary Industries and Regional Development (DPIRD) convened an ecological risk assessment (ERA) of the fisheries that access the North Coast Demersal Scalefish Resource (Resource). This Resource comprises a large number of tropical demersal scalefish species that occur in waters of the North Coast Bioregion, including tropical snappers, emperors and cods.
This document contains the results of the ERA along with the background information used to support the risk scoring process. This includes an overview of the Western Australian commercial fisheries that access the Resource, namely the Pilbara Fish Trawl Interim Managed Fishery, the Pilbara Trap Managed Fishery, the Pilbara Line Fishery and the Northern Demersal Scalefish Managed Fishery, and an overview of the recreational and charter fisheries that access the Resource
Western Australia’s agricultural R&D ecosystem
No full textDecades ago, the agricultural R&D ecosystem in Western Australia (WA) was fairly simple with few funders and some key providers of R&D services such as the Department of Agriculture, CSIRO and the University of Western Australia. Since then, the agricultural R&D ecosystem in WA has increased in complexity with more R&D providers and a greater injection of industry and private funding. These changes have occurred against a backdrop of the total investment in agricultural R&D declining as a share of agriculture’s gross value of production. State and federal governments have reduced their share of the total investment in agricultural R&D. Despite the changes in WA’s agricultural R&D ecosystem, productivity growth in WA agriculture has remained impressively high. Many farmers and local consumers of WA agricultural products and foods continue to benefit from this productivity growth. A rising need amid WA’s complex agricultural R&D ecosystem is the provision of hubs, incentives and infrastructure that enables cost-sharing and enhanced scientific collaboration. An efficient and highly productive WA agriculture sector that can readily draw on R&D and innovation outcomes will help maintain export revenues and place downward pressure on local food prices
Effect of Clay Amendment and Strategic Deep Tillage on Soil Water Dynamics and Plant Growth Under Control Environment
No full textStrategic deep tillage (SDT) practices, such as soil mixing following the application of soil amendments, are promising approaches to alleviate topsoil water repellence and other subsoil constraints and improve crop productivity. However, there is a lack of knowledge on the effect of SDT on soil water dynamics, especially under water-limited environments. This study evaluates the effects of clay incorporation, soil inversion and deep soil mixing on soil water infiltration, surface evaporation rates, soil water storage and subsequent impacts on the below and aboveground growth of wheat (Triticum aestivum L. var Scepter) in controlled environments. Results show that soil mixing significantly improved water infiltration compared to an untreated control. Clay incorporation exhibited the highest bare soil surface evaporation rates immediately and two years post-tillage, leading to substantial water losses under warm and dry ambient conditions. Despite improving soil water storage in deeper layers, high evaporation rates in clay-incorporated soils negatively impacted wheat growth, with reduced shoot biomass and root length density. Conversely, soil inversion and mixing-only treatments demonstrated balanced improvements in water infiltration, soil water use, and wheat shoot biomass. These findings underscore the trade-offs associated with SDT practices, particularly in managing soil water loss and crop productivity in water-limited environments. This study also highlights the need for the careful selection of SDT for soil amelioration strategies tailored to soil types and climatic conditions to enhance agricultural productivity and sustainability
WA Insecticide Guide 2025 - Autumn Winter
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.https://library.dpird.wa.gov.au/fc_pestfactswa/1020/thumbnail.jp
Pastoral land condition: Kimberley land condition standards
No full textThis report outlines the conceptual basis and quantitative land condition standards that define acceptable pastoral land condition for the Kimberley, Western Australia (WA), to meet the regulatory requirements of the Land Administration Act 1997 and the Soil and Land Conservation Act 1945.
The Department of Primary Industries and Regional Development (DPIRD) develops regional-level pastoral land condition standards for WA to implement the Framework for sustainable pastoral management – Revised edition, which is designed to address the Office of the Auditor General’s recommendations to improve the management of pastoral lands in WA. The application of these standards is expected to result in improved pastoral land condition.
Section 2 of this report summarises the Kimberley’s regional geography, climate and pastoral history. Section 3 describes how land condition and land management are used to determine the risk of future land degradation. Section 4 explains how the standards were developed. Section 5 provides detailed information about the Kimberley rangeland types, key rangeland vegetation groups and the standards for each rangeland type.
DPIRD will apply the principles outlined in Section 4 to develop land condition standards for each of the pastoral regions of WA
Fisheries Research Report No. 354: Recreational fishing for Abalone in Western Australia in 2024/2025 - estimates of participation, effort and catch
No full textThe Western Australian Recreational Abalone Fishery (RAF) operates in shallow coastal waters as a hand collection fishery while wading or diving. Three species of abalone are allowed to be caught. Roe’s abalone (Haliotis roei) are generally collected while wading from the shore in accessible nearshore reef complexes along the West and South Coast Bioregions. Greenlip abalone (H. laevigata) and Brownlip abalone (H. conicopora) are collected while wading (including snorkelling and freediving) and diving (using compressed air) predominantly along the South Coast Bioregion.
Recreational fishing for the three abalone species is licensed and highly regulated, especially in the Western Zone (which includes the Perth Metropolitan Roe’s Abalone Fishery) where fishing is only permitted for a one-hour period on four days per year. The northernmost part of the Western Zone (the Mid-West Region from Moore River to the Greenough River Mouth) was also open to recreational fishing for the 2024/25 fishing season for the first time since 2011
Skeleton Weed Program 2024-25: Annual report to grain growers
No full textSkeleton weed is a major pest of grain crops and can significantly reduce grain crop yields by competing for moisture and nutrients (mainly nitrogen), due to its deep perennial root system.
Skeleton weed is a declared plant in WA under section 22 of the Biosecurity and Agriculture Management Act (2007) and is assigned to control category 2 (Eradication) for the whole of the State, except in the Narembeen and Yilgarn Shires, where it is category 3 (Management).
Modelling indicates that under a nil management scenario, the cost to WA broadacre agriculture will be approximately 2.8 million per year.
With annual program costs of approximately 15.8 million over twenty years
