Doublegee (Emex australis Steinh.) seed banks
A.H. Cheam, Agriculture Western Australia, Baron-Hay Court, South Perth, Western Australia 6151, Australia.
Farmers can control doublegee, Emex australis, on an annual basis by integrating cultural and chemical control methods, but it is still not possible to achieve long-term control or eradication of this weed. It is suggested that any control measure that reduces the seed dormancy or destroys the dormant seed bank would be of immense value in the longterm management of this weed. Unfortunately, practical methods for achieving this are still unavailable. Nevertheless, some important studies on its seed dormancy behaviour and the persistence of its seed banks have been undertaken in Western Australia. This paper discusses the findings of these studies.
