    Abstract

    Parthenium weed (Parthenium hysterophorus L.) is an invasive species in more than 40 countries and a Weed of National Significance in Australia. It causes substantial losses to crop and pasture production and health problems in humans and livestock. The high invasive potential of this species is often attributed to its unique morphological features,competitive ability, and allelopathic potential; however, the level of genetic diversity in this species and how diversity contributes to its success is not currently clear. This study aimed to identify informative gene regions and sequences for the study of parthenium weed population genetics using samples collected fromits introduced range in Australia (including two distinct biotypes) and the native ranges in Costa Rica, Mexico and the United States of America.

    OtherThe 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.
