From machinery maintenance, implementing weed management plans and deciding on this year's rotations, growers are gearing up for the 2007 season... We're planting 1650 hectares of wheat, 350ha of barley, 350ha of lupins, 150ha of oats and 100ha of chickpeas... Andrew Hansen crops wheat, barley, canola, lupins, beans, oaten hay and triticale, and grazes Merinos, cattle and prime lambs on properties across the Coomandook to KiKi areas of south-eastern SA, as part of a family-run enterprise...

Including a legume pulse manure phase as well as a pulse in my continuous crop system is the plan for the future to provide 'home grown' organic nitrogen... The right pulse selection will provide a cash return as well as benefiting future crops... A pulse manure has many benefits and will add robustness and more balance to Neil's system as a manure phase mimics a pasture in that it can produce up to 200 kg/N/ha, providing background nitrogen for about 2 cereal crops as well as opportunities for IWM and a moisture conserving fallow...

The paper will review the nature and origins of these new pathotypes, and indicate the expected changes in variety response for the 2008 season... These three isolates look different on these wheats, and so we give each the name of 'pathotype', ie it is a 'type' of the pathogen... The first major pathotype change in the WA pathotype occurred in October 2006 when isolates collected from Coleambally (NSW) and Horsham (Victoria) showed the ability to cause disease on plants with the Yr17 resistance gene...

These three isolates look different on these wheats, and so we give each the name of 'pathotype', ie it is a 'type' of the pathogen... The second pathotype change was detected among isolates collected early in the 2007 season, and these showed the ability to cause disease on certain triticale varieties, notably Jackie and Breakwell...

Recently the top five diseases in wheat and barley have been estimated to cost growers in the northern region $261 million annually (wheat $183 m and barley $78 m, Murray and Brennan 2009)... The unit has a long history of effectively developing and delivering IDM strategies to support industry in minimising losses to and reducing the risk of the key cereal and pulse diseases in the region... Minimise risk of virus by retaining standing stubble, planting on time and at optimal seeding rate for rapid canopy closure...

Yellow spot is caused by a fungus ( Pyrenophora tritici-repentis ), which survives between crops on wheat stubbles... Dr Simpfendorfer is concerned that many growers and advisers believe they can control yellow spot with fungicides, as they do for stripe rust, even though the research clearly shows this is not the case... Once the fungicide wears off in a leaf, after about three weeks, it can get rapidly reinfected off the stubble if there are moist conditions."..

Yellow spot - managing high inoculum loads going into 2011 and a review of fungicide response... Given that timing is the most important factor in fungicidal control, the onus is on growers and agronomists to monitor crops closely...
