The farm in Western Australia’s Great Southern region is Australia’s first known case of GM canola contamination, and Marsh has had his organic certification revoked as a result.
The Monsanto Round-Up Ready Canola was being grown on a neighbouring farm after a moratorium on growing GM crops was lifted a year ago by the WA Liberal government.
Marsh found that the GM canola had blown over a 1.5 kilometre swathe of his property, well beyond the flimsy 5 metre “exclusion zone” stipulated for GM crops under WA guidelines.
Marsh has launched legal action for the damage caused by the contamination, which has lost him the premium price for his crops.
Organic wheat can sell for up to $500 to $800 more per tonne than regular wheat, and the fact that GM seeds can remain viable for several years means that more than half his farm has now been rendered useless.
