The aim of this research was to identify effective post-emergent herbicidal options for witch grass control.

Sheep are an integral part of low-medium rainfall mixed farming systems across southern Australia and they account for 23% of Australia’s total livestock emissions. Apart from the contribution to anthropogenic greenhouse gas emissions, the energy lost as methane represents a significant inefficiency in sheep production systems. Therefore, maintaining or improving the balance between forage and animal productivity, and methane emissions is likely to be a challenge under a warmer and drier climate. The aim of this trial is to evaluate pasture/forage options to fill in the late-spring, autumn and early winter feed gaps; and to measure comparative animal production, feed quality and methane emissions in response to current and improved sheep feeding strategies.

For a sub-tropical grass established in the Mallee environment, to assess the pattern and reliability of growth and its potential as a fodder source using simulation models.

Barley grass is now one of the top 10 weeds of Australian cropping in terms of area infested, crop yield loss and revenue loss (Llewellyn et al. 2016). Barley grass has several biological traits that make it difficult for growers to manage it in the low rainfall zone, so it is not surprising that it is becoming more prevalent in field crops in SA and WA.

Through recent GRDC investment, the research project ‘Demonstrating and validating the implementation of integrated weed management strategies to control barley grass in the low rainfall zone farming systems’ (hereby referred to as GRDC Low Rainfall Barley Grass) has commenced. An initial grower survey of current practice and attitudes towards barley grass was undertaken in 2019 to be used as the baseline to assess changes in grower attitudes and any change in practices after the completion of the three-year project.
