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...

Pea plantings drop as canola finds favour.. Canola is booming in Western Australia as growers are attracted to the crop's economics; the trick now is to find the right balance to maintain the agronomic benefits of pulses... Despite canola offering a higher return per hectare and more marketing and weed-control options, Mr Meldrum and growers such as Ron Longbottom are quick to point out that field peas still have a crucial role to play in a balanced cropping regime...

In summary, composts in soil management programmes (for horticulture): x Reduce nutrient leaching and consequent effects on water bodies... In summary, organic agriculture can provide yields similar to conventional agriculture using natural farm inputs in place of chemical fertilisers and sprays... The rots should be able to be minimised through good field practices, chemical control, gentle washing of carrots and keeping them cool and wet at all times...

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...

Can wild chickpeas reduce the nematode problem in Australian crops.. A new international collaboration between Australia, the United States and Turkey is seeking to tap into the genetic potential of wild chickpea to create more resilient and nutritious varieties... For the Australian contribution to the project, researchers will be specifically interested in the genetic resistance of wild chickpea to the root-lesion nematode (RLN), a microscopic worm that feeds on and damages the roots of susceptible crop hosts, like chickpea and wheat, limiting the plant's ability to access soil water and nutrients, thereby stunting it growth and reducing yield...

Invertebrate pests cause major losses to the Australian grains industry... GRDC invests many resources to combat such pests, through plant breeding, biotechnology, and management options... CSIRO is committed to maintaining and developing the collections, but with government policy requiring beneficiaries to contribute to costs, support from GRDC to ensure the future availability of this important resource is recommended...
