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...

KEYMESSAGES Incorrect use of phosphine since the 1950s, has led to escalating resistance in stored grain insects which threatens the continued use of phosphine at the farm level... 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... When running a trial it is important to: 1...

Results 2008/2009 harvest HSD testing The HSD system proved its potential as an effective at harvest weed seed management system by consistently destroying over 90% of the seed of four weed species present in the chaff fraction during the commercial harvest of a wheat crop... 39 (3.3) 1.0 (0.1) 1 Seed in straw were calculated by difference from seed proportions in grain and chaff samples 2 Proportion of annual ryegrass seed in unprocessed chaff surviving HSD treatment 2009/2010 harvest HSD testing High weed seed destruction levels were maintained by the HSD system when subjected to processing high amounts of chaff during the commercial harvest of high yielding wheat, barley and lupin crops (Table 2)... Conclusion Evaluation of the HSD system in commercial harvest situations has determined this system is highly effective (>90%) in destroying annual ryegrass, wild radish, brome grass and wild oat seed during harvest...

Growers that have the weed seed bank under control will save herbicide costs; be able to use diverse tactics that would otherwise be cost prohibitive; and, by reducing the frequency of herbicide applications, will delay the onset of herbicide resistance... With any discussion on managing resistance we need to start with the basics and understand why we have the problem in the first place... Registration of high application rates by this technique may allow the control of resistant weeds that have survived a preceding application of a different mode of action...

For example, at Dubbo 407 mm of rain fell on 68 days (39 days >1.0mm) between 01 June and 30 November, compared with a long-term average of 282 mm on 43 days (34 days >1.0mm)... The pattern encouraged rapid vegetative growth of crops and was ideal for the build-up and spread of the major chickpea pathogens... Ascochyta blight (AB, caused by Ascochyta rabiei ), Botrytis grey mould (BGM, caused by Botrytis cinerea ), Phytophthora root rot (PRR, caused by Phytophthora medicaginis ) and Sclerotinia rot (caused by Sclerotinia sclerotiorum and Sclerotinia minor ) were widespread and severe in many crops...

For example, at Trangie 386 mm of rain fell on 54 days (40 days >1.0mm) between 01 June and 30 November, compared with a long-term average of 225 mm on 41 days (28 days >1.0mm)...
