Abstract
The problematic weed silverleaf nightshade (Solanum elaeagnifolium Cav.) was introduced to Australia during the early 20th century from North America and has since emerged as a Weed of National Significance. This species is almost impossible to eradicate after establishment, with its management in areas of new emergence therefore much aided by prompt identification and early action. Identification of the weed is often confounded because of the weed’s remarkable similarity (especially pre-floral stages) toa variety of native Solanum species. DNA barcoding for improved identification may therefore improve its management. Sequences of the nuclear waxy geneand two chloroplast genes (matK and trnL-trnF) were compared among S. elaeagnifolium (N = 12) and 10 native species (S. brownii, S. centrale, S. coactiliferum,S. esuriale, S. jucundum, S. lasiophyllum, S. lithophyllum, S. petrophilum, S. quadriloculatum and S. sturtianum) with which the weed is commonly confused.A further five species including S. campanulatum,S. chenopodinum, S. cleistogamum, S. nummulariumand S. succosum, were also analysed to provide a wide cross-section of Australian native species.

| 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. |
