"In preliminary glasshouse and field trials, we have found that acacias inoculated with beneficial strains of a nitrogenfixing bacteria called Bradyrhizobium survive better and grow faster than un-inoculated acacias," Dr Thrall says... Of particular interest is the extent to which re-introduction of beneficial organisms helps plants to withstand environmental stresses like soil salinity and competition with exotic weeds...

, if a pathogen change occurs where the ASR gene is overcome (such as Yr17 in the Western Ausralian pathotype lineage of wheat stripe rust in 2006), the APR gene/s provide back-up resistance, protecting the crop from catastrophic yield losses... In recent years, varieties have been released that lack ASR genes but carry several APR genes pyramided to provide excellent levels of stripe rust resistance as adult plants... Adult plants of LongReach Spitfire are only expected to lose a maximum of 30 per_cent of their leaf area to stripe rust infection...

Although a high-risk crop, oaten hay has the potential to outperform all other cereals with respect to gross margins... The widespread use of genetic analysis in agriculture is limited by economic factors... In the short term, fungicides used at seeding (seed dressings or applied in-furrow with fertiliser) and foliar fungicide sprays will mitigate risk and minimise losses...

Overall, 60-70 per cent of flour is used in traditional flat breads, 20-25 per cent of flour is used in western style breads and 5-10 per cent is used in cakes and biscuits... In summary, canola varieties sown 2-3 weeks earlier than normal (early to mid April) can be grazed in winter prior to bud elongation (usually providing 600-800 dse grazing days/ha) and recover with no impact on yield or oil...

It was proposed that DRB be isolated and evaluated against ARG. Successful organisms were then to be applied in high numbers and assessed in field situations... Until the mode of action of these bacteria is clearly defined and/or a rapid isolation and assessment protocol (perhaps with the aid of gene technology) identified, this project needs to be shelved... It was proposed that DRB be isolated and evaluated for annual ryegrass - with the aim of inhibiting seed set and subsequent annual ryegrass toxicity reduction...
