Chilean needle grass (Nassella neesiana [Trin. & Rupr.] Barkworth) and serrated tussock (Nassella trichotoma [Nees] Hack. ex Arechav.) are related Weeds of National Significance (WoNS) undergoing rapid range expansion in Australia. They are difficult to distinguish from native tussock grasses and emergences of these weeds often remain undetected until after they have established as difficult to control populations. Genetic diagnostics using loop-mediated isothermal amplification (LAMP) may provide a simple cost-efficient means for rapid identification of these weeds, under laboratory and field conditions. Provision of LAMP diagnostics would assist in minimising the time-lag to initial recognition of tussock weed outbreaks in new areas, and subsequently improve the time to response for eradication of the weeds where they are recently emergent.

|Period||09/09/18 → 12/09/18|
|Other||The Weed Society of New South Wales Inc., on behalf of the Council of Australasian Weed Societies Inc., will be hosting the 21st Australasian Weeds Conference in the popular Sydney beach side suburb of Manly from 9 - 12 September 2018. An assortment of field trips will be hosted on Thursday 13 September 2018.|
This biennial conference carries on a long tradition of bringing the weed management community together to discuss new developments and share information about cutting-edge and best weed management practices.
The conference attracts over 250 delegates from across Australasia and globally. Delegates will come together to network with peers, engage with industry sponsors, listen and participate in presentations and field trips on a variety of topics including;
- New technologies in weed management.
- Biological, mechanical, and chemical weed control and research.
- Herbicide resistance.
- Weeds of crops and pastures.
- Environmental weeds and Weeds of National Significance.
