How Sclerotinia moves from canola stubble into the whole of a farm’s crop rotation is under investigation in the northern and southern growing regions with the aim of learning how to manage or possibly break the disease cycle

Blackleg disease is constantly changing with respect to the effectiveness of genetic resistance and disease epidemiology – as well as through changes in stubble management

After a wet spring, researchers across Australia have warned that severe disease pressure will require proactive management to minimise damage to this year’s grain crops. Having a good integrated disease management strategy will be critical in reducing grain yield losses.

Knowing the presence of resistance genes in a variety is important in predicting and explaining how a variety will perform if and when a new rust pathotype appears. This is well illustrated by the events that unfolded following the introduction of wheat stripe rust pathotype 198, which originated from either Europe or South America.

An upgrade in the ability to protect chickpea crops from Ascochyta blight (Ascochyta rabiei) is being engineered through five research programs that are working in lockstep to overcome key disease control limitations

A short study by NSW DPI, supported by GRDC, has found that it appears that oats could provide some benefit in reducing in-crop yield loss from Fusarium crown rot compared with other cereals within NSW farming systems. However, oats might not necessarily reduce paddock inoculum levels or, therefore, the Fusarium crown rot risk.

A three-pronged strategy is being deployed in a GRDC project led by the South Australian Research and Development Institute to provide a step change in breeding for Septoria leaf blotch resistance in oats. By better understanding the virulence and diversity of the fungus, identifying potential new sources of resistance in international germplasm sets and developing molecular markers to fast-track breeding efforts the project team is endeavouring to accelerate breeding progress for this economically significant disease.

Management of oat crown rust has always been challenging as populations of the fungus evolve rapidly. Control through the development and use of varieties with durable genetic resistance is the most economical and environmentally friendly method but progress has been slow. GRDC have upped the ante in the race to manage the disease through the deployment of new technologies, resources, and collaborations.
