Rust Disease And Its Management In Faba Beans, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Faba bean rust (Uromyces viciae-fabae) is host specific, meaning it does not infect cereals or other break crops. The rust is not widespread in Western Australia but low to moderate levels occur in the Esperance and Katanning regions. Individual crops suffer yield losses in some years.

Rust has also been recorded in the high rainfall region in the northern agricultural area, around Dongara.

This page summarises the symptoms, infection cycle, disease risk and spread, and management recommendations for faba bean rust disease.

Spray-Topping Pastures, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Spray-topping or pasture topping is the application of a sub-lethal rate of herbicide when grasses are coming into head and flowering.

The aim is to reduce the production of viable seed and the seedling population in the following year. The grass is not killed by the herbicide application.

Spray-topping is normally carried out in preparation for the following season's cropping program.

Leaf Diseases And Their Management In Oats, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Leaf diseases of oats impact on grain yield and quality and reduce hay quality characteristics, such as colour and digestibility. This page outlines the symptoms, factors favouring disease risk and spread, and management.

Major leaf diseases of oats are septoria avenae blotch, stem rust, leaf rust, and barley yellow dwarf virus. Their severity changes with seasons.

Foliar Diseases And Their Management In Lupins, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

This factsheet describes symptoms and management of the major fungal and viral diseases affecting lupin foliage, stems, and pods. Several of these diseases have the capacity to cause significant losses if not managed effectively.

Inoculum can be carried in soil, seed, stubble, on green regrowth, or by insect vectors, depending on the disease. Therefore, an integrated approach to disease management is required using tactics such as crop rotation, stubble management, fungicide seed dressing, variety selection, and seed testing

Are You Planting Resistant Weeds With Your Crop Seed?, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Key messages

• West Australian (WA) grain growers have significant weed seed contamination in their crop seed.

• WA growers are sowing herbicide resistant weed seed into their cropping paddocks.

• Crop hygiene (harvest, seeding, transporting) is important to minimise spread of weeds.

Harvest is well underway throughout the WA grainbelt, and growers will be harvesting grain and collecting seed for next year’s crop.

However, this crop seed can be contaminated with weed seeds and, if seed cleaning operations are only partially effective, this weed seed may be sown into paddocks with crop seed in the following season.

Russian Wheat Aphid And Its Management In Wheat And Barley, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Russian wheat aphid is found worldwide and has spread throughout all major grain growing countries. In Australia, Russian wheat aphid is present in South Australia, Victoria, New South Wales, Tasmania, and Western Australia, where it was first detected in 2020.

In Western Australia, Russian wheat aphid is found in low, medium, and high rainfall areas.

Presence of Russian wheat aphid in Western Australia is not an international trade issue and there are no trade implications for the grain industry, as bulk grain is not a host for Russian wheat aphid.

Managing Aphids And Viruses In Lupins, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Aphids reduce yields by direct feeding damage, which causes flower and pod abortion and occasionally plant death in lupins. The extent of damage varies between seasons, but losses can be severe in years that favour aphid population development.

Lupins are most vulnerable to aphids during budding and flowering, as severe feeding damage on growing tips can cause buds to drop, flowers to abort, and reduced pod set. Some lupin varieties are more susceptible to aphids than others.

Aphids transmit serious virus diseases, which reduce yields and contaminate seed stocks. Some species of aphids are more difficult to control than others.

Native Budworm Spraying Threshold, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

The number of native budworm caterpillars in a crop is the major factor determining potential economic damage from the pest. Table 1 was generated with results from department trials to provide an estimate of potential loss from native budworm damage.

Crop loss (kilograms per hectare (kg/ha)) for each caterpillar netted in 10 sweeps (or found per square metre (m2 )) is shown in Table 1. One caterpillar netted in 10 sweeps is equivalent to about 20,000 caterpillars/ha for most pulse crops, assuming an even distribution over the crop

Stem Rust And Its Management In Wheat, Department Of Primary Industries And Regional Development, Western Australia

Developing A Controlled Traffic (Tramline) Farming System, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Controlled traffic farming (CTF) is a farming system built on permanent wheel tracks where the crop zone and traffic lanes are permanently separated. It can improve profitability and sustainability.

Implements for seeding, spraying, spreading and harvesting have a particular span, or multiple of it, and all wheel tracks are confined to specific traffic lanes.

CTF increases profit by more yield, better grain quality, improved operation timeliness, and reduced costs. The environment can improve, with less nutrient leaching, less water erosion, better water infiltration, and less greenhouse gas emission. Implementation needs a clear, long-term plan, and prioritisation of soil health.
