During the first field trip (August 2), Prof Tuberosa visited three different experimental sites near Adelaide where a number of new experimental materials were being evaluated alongside already released varieties... During the second field trip (August 22), he visited three different farms where durum is grown and an experimental site where new materials were being evaluated for their agronomic performance... As a member of the steering and program committee of InterDrought-III (October 10-14, 2009, Shanghai, China,) and in view of the strong interest in drought-related research at ACPFG, the inclusion of Prof Mark Tester in the scientific committee of InterDrought-III has been suggested...

A disease control model for crown rot in Victoria and South Australia (SA) which provides crop management recommendations to reduce the build-up of Fusarium inoculum and avoid sowing into high disease risk situations... Crown rot is highly spatially variable, so intensive and extensive sampling programs were undertaken to assess the the reliability of results produced using current sampling protocols... Intensive stubble and soil sampling was used to assess the scale of spatial variability of crown rot and whether taking soil cores in a row crop was causing "spikes" in results...

Durum wheat growers urged to stay ahead of crown rot risk.. Growers of durum wheat are being encouraged to test their paddocks for the soil-borne disease crown rot before embarking on this year's sowing programs... The potential yield loss due to crown rot is much greater in durum than bread wheats, so paddocks reported with a medium or high risk are switched to bread wheat, as part of their risk management strategy...

Crown rot remains a threat under irrigation.. Cotton growers moving into irrigated grain production are being warned to manage the damaging cereal disease crown rot, which can cause major yield losses when moisture stress occurs during grain fill... Losses to crown rot can be dramatically reduced in irrigated crops by a range of management options and carefully considering the scheduling of water to limit moisture stress during grain fill."..

What began as a quick internet search to learn more about the possible causes behind the leaf spotting that was affecting wheat in north-west NSW has led to a new discovery for Australia - that a lack of the nutrient chloride may not only cause spotting, but may also lead to delayed flowering and increased lodging... Chloride deficiency in bread wheat can affect yields without producing any leaf spots.].. A lack of chloride can also affect moisture regulation in the plant because chloride helps open and shut the stomata (the plant's valves) keeping moisture in," he says...

Figure 1 Chloride fertiliser application rate affects the whole plant tissue concentration of chloride.. Since then, we carried out several further chloride addition field experiments across the Liverpool Plains in 2009 and we report the results of those ... The durum advanced yield trials consisting of current varieties and elite breeding lines at Tamworth Agricultural Institute and on-farm at Currabubula both exhibited severe chloride deficient leaf-spotting symptoms and we report the results of tissue testing and leaf-spot scoring / measurement on all 32 lines grown at those trials (leaf-spot scoring only available for Currabubula)...
