Vigilance call for barley leaf rust.. Mr Platz urges growers to be alert to the risks of a leaf rust outbreak: "The risks may be low this season, but that's no reason to become complacent," he says. ".. "Managing the disease requires a community effort, so if a grower locates leaf rust they should alert their regional departmental pathologist so a general alert can be issued," Mr Platz says...

Moisture probes put hard data into crop planning.. Bruce says he installed the probes for three reasons: to assess how much moisture is in the profile to help with crop planning; to ensure nitrogen is not wasted on crops that do not have sufficient subsoil moisture to support additional biomass production; and to assist with marketing decisions - as an accurate picture of available moisture will help, particularly if they forward sell their grain... Bruce says the controlled-traffic farming system, introduced in 2006, has several benefits including: a 20 per cent reduction in fuel use; better soil structure, improving water infiltration and plant root development; better paddock access enabling more timely applications; and the ability to more easily implement inter-row planting of crops into the previous year's stubble...

Our aim was to investigate the interaction of nitrogen and fungicide in the control of yellow spot in wheat varieties of varying yellow spot resistance... The results of the trial suggest that nitrogen and fungicide are each effective on their own, and also in combination, for managing leaf spot diseases on susceptible wheat varieties... Nitrogen application increases the vigour of wheat plants and number of tillers and can increase yield and may allow for fungicide application to be more effective, particularly on susceptible wheat varieties...

Rhynchosporium secalis (scald) is one of the major diseases of barley in Australia... ANU00007 has shown that barley grass contributes to virulence diversity in scald populations... In support of and to extend this work the project has also continued to collect, store and characterise a large array of scald isolates from around Australia to determine which resistances available to breeding programs are likely to be most effective when widely used...

Western Australian barley growers have a new weapon against powdery mildew thanks to a permit allowing them to use an alternative fungicide to combat the costly disease... Professor Richard Oliver, from the GRDC-supported Australian Centre for Necrotrophic Fungal Pathogens (ACNFP), said the permit provided another tool to manage powdery mildew, which caused losses of up to $100 million in WA last year. ".. SEPWA president Lyndon Mickel welcomed the announcement of the permit allowing the use of spiroxamine for control of barley powdery mildew in WA, saying it gave growers another tool in the toolbox to manage the disease. "..
