AUS – GM CANOLA UNLIKELY TO BE INVASIVE
19 January 2016 – Source: ABC Rural
West Australian scientists say escape of genetically modified herbicide-resistant seeds into native bushland and roadsides can occur, but it is an easily manageable situation.
Publishing in the journal Agriculture, Ecosystems and Environment, the University of Western Australia’s Australian Herbicide Resistance Initiative’s Professor Stephen Powles and Dr Roberto Busi studied populations of escaped seeds.
The seeds were in two areas of native bushland where GM canola had blown from in-paddock windrows, and on a roadside where seed had spilt from a truck near a grain receival site in Perth’s eastern suburbs…
In one area of native bushland near the Quairading crop, Professor Powles said GM canola completely failed to establish beyond the first generation…
In a different area, the seeds did establish, but became extinct after three years.
On roadsides, where it is common for landowners and councils to use glyphosate to control weeds, the GM canola had a better chance of establishing because competition from other plants was eliminated.
But Professor Powles said controlling the canola was simply a matter of mixing alternative herbicides together…
The study was funded by the Grains Research and Development Corporation.
