Mention of a trade name or company in this publication does not imply endorsement of any product or company by the Department of Agriculture and Food, Western Australia... 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...

Overall, barley diseases have the potential to cause very significant costs for farmers... Incidence is 30 per_cent frequency in 30 per_cent of the area, so that the average incidence of the disease affecting the crop is 9 per_cent... Overall, breeding contributes more than 25 per cent of the control for 14 diseases, cultural methods for 32 diseases, and pesticides for six barley diseases...

Net blotches (Pyrenophora teres f. teres and P.t. f. maculata) remain the major diseases of barley in the northern region... While net form net blotch (P.t. f. teres) can be the more devastating disease, resistance to the disease is present in several of our leading varieties... Seed harvested from crops heavily infected with net form net blotch should not be retained for sowing...

Barley stripe rust (Puccinia striiformis) is currently an exotic disease and barley grass stripe rust can attack some susceptible barley varieties... Stem rust survives the summer mainly on volunteer wheat, barley, triticale and some grasses including common wheat grass and barley grass... The most effective way to control the rusts of barley is to grow varieties with resistance or avoid growing those that are rated as very susceptible or susceptible to each disease...

Vigorous plant growth and high water use efficiency make barley an excellent choice for double cropping from a summer crop back to a winter rotation... Fitzroy has good levels of resistance to net form of net blotch, but it is susceptible to powdery mildew, leaf rust and spot form of net blotch... Shepherd is resistance leaf rust and most net form of net blotch isolates, but it is susceptible to the spot form of net blotch and a new isolate of powdery mildew...

Cereal rust strains provide clues to resistance.. Cereal rust pathotypes - which are races or strains of the disease that vary in their ability to overcome resistance genes in cereal varieties - are common in most Australian wheat, barley, oat, rye and triticale crops... All barley cultivars carrying this resistance gene are currently resistant to leaf rust in Western Australia, while in eastern Australia, some are moderately susceptible to susceptible...

Influence of fungicide rate (mean of fungicide products - four site mean) Stem rust control assessed over the four trial sites revealed that using high rates was essential for the control of the disease, even if the fungicide had been applied prophylactically (before infection was visible in the crop)... Influence of cultivar resistance and fungicide application (Prosaro ) on yield and stem rust severity measured on the flag sheath 18 days after fungicide application at early dough (GS82) and assessed at mid dough - physiological maturity (GS85-90) - Bairnsdale, Gippsland, Victoria, 2010... The yield potential for the crop with no nitrogen applied is estimated at GS30 from the results of numerous of trials conducted in that region where NDVI at GS30 is divided by the number of growing degree days (GDD) greater than 0 C since planting, referred to as the INSEY units (in season estimate of yield)...
