Livingston is one of few varieties that has moderate tolerance to root lesion nematodes (RLN), along with other desirable features... The researchers concluded that where Pt combines with high levels of crown rot (a common scenario), yield losses can be exacerbated if varieties are susceptible to Pt. Instead of a 10 per cent yield loss from Pt in a susceptible variety it could be 30 to 50 per cent if crown rot is combined with a Pt-intolerant variety...

The project will undertake an ambitious field program across South Australia and Victoria to evaluate the different resistance genes available to wheat breeding programs to determine the level of resistance required to manage CCN, Pratylenchus neglectus and P. thornei populations in current farming systems, and develop recommendations to breeding companies on the need for resistant and tolerant varieties across the southern region... To improve recommendation to growers, the project will also assess tolerance of current wheat and barley varieties to CCN, P. neglectus and P. thornei and update guidelines on use of nematode resistant and tolerant varieties to minimise yield losses, including revising the risk categories based on initial nematode levels... A new research officer Sjaan Davey, has been appointed to this project and in collaboration with Dr Grant Hollaway,DPI Vic (via GRDC project DAV00104), and Bev Gogel and Prof Brian Cullis (GRDC project, Statistics for the Australian Grains Industry), is co-ordinating field trials in SA and Victoria to check the calibration of the pot experiments used to classify the resistance levels to CCN, Pratylenchus neglectus and P. thornei in new varieties, and is developing a field program to assess how well new varieties tolerate the nematodes in the current farming systems...

South Australian and Victorian researchers are working to gather enough information to pre-empt a re-emergence of cereal cyst nematode (CCN) disease and its ability to cause significant problems in cropping regions... While use of resistant varieties in the past has kept CCN populations under control, they have not eradicated CCN from soils... Dr McKay says establishing how to use new varieties to manage CCN populations will enable information to be provided to growers to better inform them of which varieties will keep CCN under control and which combination of varieties are likely to increase risk of a resurgence...

The overall objective of this research program is to develop and deliver strategies for management of plant diseases of importance to SA grains industries... The increased frequency of cereals and greater adoption of susceptible cultivars is creating an opportunity for cereal cyst nematode (CCN) to re-emerge as a significant problem in the southern region... Subproject 3 continues existing monitoring and surveillance of new races and pathogen threats; this subproject will link with newly appointed grains biosecurity officer in SA. Subproject 4 focusses on rebuilding a joint capability in the southern region to address key issues in cereal nematology, most critically preventing CCN re-emerging as a significant problem...

The checklist gives growers a comprehensive 'to do list' that will help growers maximise the potential that each year offers so they will be satisfied when harvest rolls around and yield and protein levels come in... Rotations - top of the list is the selection of crops and varieties as rotations, summer and winter, have become essential to our farming system in terms of controlling weeds and diseases...

Early prediction of soilborne disease could cut losses.. DAFWA project leader Martin Harries said soilborne diseases were a major cost to the cropping industry, estimated to cause losses in WA of about $100 million per year in cereals alone... "There is scope to reduce these losses through management actions - such as choice of crop type or application of fungicide seed dressings - if these pathogens can be more accurately detected and quantified prior to sowing," he said...
