Wild radish management and strategies to address herbicide resistance
Read more about this factsheetWild radish (Raphanus raphanistrum) is one of the most widespread and competitive broadleaf weeds of Australian cereal-growing regions. Increasing resistance to multiple herbicide modes of action is forcing growers to adopt diverse and integrated weed-control strategies to deal with this weed.
Common weeds of grain cropping
Read more about this factsheetGRDC's 'The Common Weeds of Grain Cropping – The Ute Guide' aims to help growers, advisers, researchers and students to identify the most common weeds of grain cropping systems in Australia.
Northern IWM factsheet – common sowthistle
Read more about this factsheetCommon sowthistle (Sonchus oleraceus L.), also known as milk thistle, is a dicotyledonous annual weed. The plants are erect and fleshy and possess hollow, smooth stems that exude a milky latex when damaged. The weed can grow up to 1.5 m in height. Plants of common sowthistle can be either present as a rosette or upright in their growth form.
Windmill grass – Northern Region
Read more about this factsheetWindmill grass (Chloris truncata R.Br.), also known as umbrella grass or blow-away grass, is a short-lived perennial species that has recently been identified as resistant to glyphosate. This weed is becoming more dominant in southern Australian farming systems.
Mixing requirements for spraying operations
Read more about this factsheetMixing order is very important to ensure that tank mixed products perform to their potential. Understanding formulation type and adjuvant type are an important part of getting the mixing order right. If in doubt about the compatibility of products in a tank mix, contact the manufacturers and conduct a jar test to ensure they will mix.
Alternative second knock herbicides for broadleaf weeds in fallow – are there other options?
Read more about this factsheetThe sequential application of two separate herbicide treatments has become the most common ‘double knock’ approach used in weed management. Unfortunately, these approaches have added cost, complexity and scheduling issues to weed management programs but have been required for two main reasons: 1. To control herbicide-resistant weed populations, that may have been selected by prolonged use of a similar mode of action chemistry; and 2. Control of weed species or stages that are unsuccessfully controlled with single herbicide applications.
Alternative Herbicides for Management of Group A Herbicide-Resistant Barley Grass in Field Pea
Read more about this factsheetBarley grass is a problematic annual weed species in Australia, typically growing in areas with less than 425 mm of rainfall. It is commonly found in crop fields and pastures, on roadside verges and in livestock enclosures.
Windmill Grass: Biology
Read more about this factsheetWindmill grass (WMG) is a short-lived perennial grass species that has been problematic in the northern cropping region of Australia and is now becoming more common in the southern region. It establishes on roadsides and in summer-fallow, where over-reliance on glyphosate has led to the development of resistance. An understanding of windmill grass biology will […]
Feathertop Rhodes Grass: Biology
Read more about this factsheetAlready a major weed in the northern cropping region of Australia, Feathertop Rhodes grass (FTR) is now occurring in fields in the southern and western cropping regions. FTR has been favoured by the shift towards reduced tillage. In addition, the heavy reliance on glyphosate that typically accompanies reduced tillage has led to resistance, further increasing […]
Statice: Biology, Ecology and IWM Tactics
Read more about this factsheetStatice (Limonium lobatum) is a winter annual dicotyledonous weed of Mediterranean origin that has naturalised inland and along some coastal areas of southern Australia. This herbaceous weed from the Plumbaginaceae family is often found in areas of low to moderate rainfall on sandy to loamy soils that are calcareous, sodic and of neutral to high […]
Stewardship for pre-harvest application of herbicides in winter crops
Read more about this factsheetThe application of herbicides late in the season to prevent weeds setting seed or to desiccate crops must be carried out with caution and in line with herbicide label recommendations. Download the factsheet for more information.
Long-term Control and Seedbank Depletion of Annual Ryegrass: Management Strategies
Read more about this factsheetAnnual ryegrass is a major winter annual weed of the southern Australian wheat-belt, which naturalised after its introduction as a pasture species. If not managed effectively, ryegrass can significantly reduce the yield of winter crops.
