Tips and Tactics: Cereal Cyst Nematode, 2017
- Be aware of the risk of cereal cyst nematode (CCN) and monitor paddocks if growing susceptible varieties.
- CCN affects wheat, barley, oat and triticale and can cause yield losses >70% in intolerant varieties.
- CCN is most widely distributed in sandy and clay soils in South Australia and Victoria. It is not regarded as a pest in Queensland nor most of New South Wales but is a problem in some parts of southern NSW and Western Australia.
- Check current cereal disease guides to determine the resistance rating of varieties (see state government websites and National Varieties Trial Online).
- CCN can be identified in spring when the cysts become visible on the roots of affected plants.
- Have your agronomist test paddocks before choosing varieties.
- If you have been growing susceptible cereals, make sure you rotate crops and remain vigilant.
- Once a crop is affected, very little can be done to protect that crop.
- If you had CCN this season, sow a resistant variety or non-host crop next season.
