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...

Ascochyta confirmed in CQ chickpea crop.. Dr Moore urged growers to vigilantly monitor crops for early signs of Ascochyta blight infection, particularly given above average winter rain in many areas and the Bureau of Meteorology's forecast of neutral to La Ni a climate conditions by spring for northern Australia... "BGM could present more of a threat to crops this season than Ascochyta with the mild, wet conditions in winter producing high biomass crops and this, coupled with a wet spring will favour BGM."..

Nipper lentils and PBA Rana faba beans require additional fungicide sprays due to ascochyta resistance breakdown... Ascochyta blight in chickpea cultivars and breeding line; reactions range from Resistant to MR-MS, requiring different spray strategies... Multiple sprays were required later in the season to maintain disease control...

The rainfall pattern encouraged rapid vegetative growth of chickpea 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 both Sclerotinia sclerotiorum and Sclerotinia minor ) were widespread and severe in many crops... Timely and thorough applications are critical...

Although ascochyta blight has been present in Central Queensland for the past six years, Mr Cumming said the incidence and severity had remained low due to dry winters and the concerted management efforts by growers and advisors... "The most significant risk to the introduction and spread of ascochyta blight to a farm is through the introduction of infect chickpea crop residues and maintaining strict farm hygiene remains the primary line of defence," Mr Cumming said... The revised management strategy has been developed by Pulse Australia in conjunction with key industry stake holders, including the USQ/Queensland Department of Agriculture and Fisheries (DAF) pulse pathology team...

Central Queensland chickpea growers are urged to be on the lookout for ascochyta blight and be ready to apply a fungicide in order to prevent yield loss or seed damage for next year's planting... Julie Ferguson, Department of Employment, Economic Development and Innovation (DEEDI) industry development officer (pulse and grain legumes) says CQ chickpeas are more at risk from ascochyta infection this season than ever before and growers should keep a close eye on their crops right up until harvest... While ascochyta has not been found north of Emerald, it has made its way into chickpea crops scattered throughout CQ's southern growing areas, and Ms Ferguson says a wet end to the growing season could see ascochyta appear in crops as late as at harvest, rendering seed unusable for planting the following year...

"In central Queensland all of the commercial varieties are susceptible, or highly susceptible, to ascochyta blight and the outbreak early in the 2012 season means that there will be infected chickpea stubble in paddocks," Dr Ryley says... Mr Cumming says variety choice plays a major role in managing the disease and suggests planting varieties with greater ascochyta resistance, including PBA HatTrick or PBA Boundary , in northern New South Wales and southern Queensland... "Varieties suited to central Queensland are different to those in northern NSW and southern Queensland, and all are susceptible to ascochyta blight," Mr Cumming says...

Most chickpea cultivars grown by farmers in Mediterranean and Australian environments are susceptible to ascochyta blight, affected by terminal drought, susceptible to vegetative and flowering stage cold... Sources of resistance for Ascochyta blight, drought, and Fusarium wilt identified in the first phase of the project were introgressed into Australian adapted cultivars... To enhance the knowledge and accelerate the process of developing new chickpea varieties possessing tolerance/resistance to these traits, seeds of three recombinant inbred (RI) populations for drought, Fusarium wilt and cold tolerance have been increased...
