What Is The Best Fit For Electric Weed Control In Australia?, Miranda J. Slaven, Catherine Borger

Experimental Summaries - Plant Research

Electric weed control is a non-chemical weed management alternative that will apply to a range of agricultural systems. The current project assessed electric weed control via the continuous electrode-plant contact method (using a Zasso™ XPower).

A wide range of field trials in 2022 and 2023 investigated weed control efficiency, suitability of electric weed control for fence line control of glyphosate-resistant annual ryegrass (Lolium rigidum Gaud.), use for crop topping, fire risk, damage to the soil biota, or use for inter-row weed control in vineyards or lupin crops. Broadleaf weeds were controlled more effectively than grass weeds with electric weed …

Impact Of Soil Amelioration On Weed Ecology And Control, Catherine Borger, Arslan Peerzada Dr, Gaus Azam Dr

Experimental Summaries - Plant Research

The project focussed on three main findings from the literature review:

1. Weed ecology in response to changes in soil characteristics.
2. Soil movement and weed seed burial following use of varying strategic tillage implements; and
3. Management of weeds in the years directly after amelioration.

The work highlighted that weed growth was either less impacted by changes to soil properties than crop growth, or weed growth and competitive ability were favoured by the same amelioration techniques that favour crop growth. Following amelioration, improved growth of competitive weed species needs to be considered in weed management plans.

Research was conducted on weed seed …

Environmental Weed Risk Assessment Protocol For Growing Non-Indigenous Plants In The Western Australian Rangelands, Geoff A. Moore Mr, Christine Munday Ms, Papori Barua Dr

Bulletins 4000 -

This bulletin is a post-border environmental weed risk assessment (WRA) protocol which is based on the Environmental WRA Protocol developed for the Future Farm Industries Co-operative Research Centre (FFI CRC), but with some changes to reflect the different environment and objectives.

The WRA protocol was developed specifically as a post-border assessment of non-indigenous species that may have agricultural value in the WA rangelands and the risk that they may become environmental weeds. Weeds can occur in many land-use systems including agriculture, horticulture and forestry; however, the focus of this protocol is on the risk that non-indigenous agricultural plants may become …

Bedstraw Eradication Program 2021/22: Annual Report To Grain Growers, Department Of Primary Industries And Regional Development, Western Australia

Agriculture reports

Three-horned bedstraw is a competitive weed that can cause considerable yield loss in crops, and its seeds contaminate fodder and grain. To stop the weed becoming established in Western Australia and impacting production, WA grain/seed/hay growers (via the Grains, Seeds and Hay Industry Funding Scheme) fund the Bedstraw Eradication Program.

Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr, Meredith M. Guthrie

Bulletins 4000 -

The Bulletin is a comprehensive guide for pastoralists, agronomists, agribusiness and the broader community on the growing of irrigated crops and pastures within a rangeland pastoral setting.

Dispersed irrigation developments on stations throughout the northern rangelands (sometimes referred to as mosaic agriculture) has created opportunities for the introduction of more productive forage species and pastoralists can now grow high quality forage for 12 months of the year. This can help to overcome the key constraint of traditional pastoral systems, the low quality of the feed over the dry season that typically results in stock losing condition.

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 …

Canola Agronomy Research In Western Australia, Department Of Primary Industries And Regional Development, Western Australia, Jackie Bucat, Andrew Blake

Bulletins 4000 -

The Tactical Break Crop Agronomy Project and the Achieving Stable and High Canola Yield Across the Rainfall Zones of WA Project were initiatives originating from a Western Panel Spring Tour of the low rainfall zone. The panel was focussed on investing in research and development to support the expansion of canola into low-medium rainfall zones where it could be incorporated into short-phase cropping systems. The importance of managing nitrogen application in soil with declining organic matter as farms moved from a long pasture phase system was paramount. Furthermore, understanding the management changes required to transition from OP to hybrid canola …

Grains Research And Development Science Highlights 2015-17, Department Of Agriculture And Food Western Australia

All other publications

Western Australian grain production and industry value has quadrupled over the past 30 years, despite declining winter rainfall, more frost and high temperature events, acidifying soils and increasing input costs. Strong evidence links this productivity growth to R&D that has delivered genetically superior varieties, better agronomic practices and more reliable farming systems. Western Australian grain growers are innovators that rapidly adopt new technology which is increasingly sourced from a wider pool of national and global science, research and innovation. Continuing to push the productivity frontier is not only critical to grower’s profitability, it underpins the international competitiveness of our exports …
