Increasing herbicide resistance, together with no new modes of herbicide action, are contributing to a ‘perfect storm’ in grain growers’ ongoing battle against weeds. • The aim is to develop weed-competitive wheats to integrate with new and existing integrated pest management (IPM) strategies, thereby adding another option to the grower’s weed cont...

Barley varieties differ in how they respond to the management inputs of applied nitrogen (N) and seed rate (plant density). The relative performance of varieties was not constant as their responses changed as the environment changed. Knowledge of how a variety responded to increasing N was not helpful in understanding how the same variety responded...
-
The practical implications of nutrient redistribution within paddocks by windrowing can be approximated by measuring plant material and investigating nutrient leached after rainfall....
-
Results from two seasons showed that spading and one-way ploughing are the most cost-effective treatments for amelioration of water repellent deep sands in the West Midlands region of the WA Wheatbelt, thanks to their significant impact on yields and their medium-low cost....
-
Build-up of surface repellence is slow and is unlikely to exceed low levels within the first 10-years except in cases of incomplete soil inversion in soils with low clay content....
-
This research compares and showcases the broad range of strategic tillage options for amelioration of sandplain soils and assess es their effectiveness at overcoming a range of soil constraints and increasing crop productivity....
-
Field trials confirm that pre-emergent herbicides can contribute to poor establishment in the first year after inversion tillage....
-
Complete cost component transparency is often lacking in Australian export grain supply chains, unlike that which occurs for some of Australia’s competitors, and so perhaps greater or formal monitoring of supply chain costs is required....
-
Break crop yields decreased faster in areas with lower yield potentials (e.g. Low rainfall zone) compared with wheat, explaining the reluctance of farmers to grow break crops in such areas....

Blackleg CM, the Blackleg Management App has been developed to provide growers and advisers with an interactive interface to explore the economic outcomes of different blackleg management strategies and their relative importance....
