Maintaining, regenerating and restoring native vegetation in Australia proves particularly challenging, given the scale involved, the limited resources for such activities and the constant invasive pressure of exotic weed species. Techniques for direct seeding of native vegetation have dramatically improved in the past two decades with the development of dedicated seedbanks and efficient minimum tillage seeders.
Managing plant successions along seeding lines remains difficult as suppression of weed growth with glyphosate alone is a short term measure that inevitably leads to a flush of new competitive weeds.
This report details a project conducted to identify residual herbicides that will suppress exotic weeds for sufficient time to enable native seedlings to establish successfully in the Riverina region of New South Wales.
