A farmer employed by Percy Schmeiser says the bio-tech company Monsanto is unfairly targetting him.

Monsanto says it received a tip that 26-year-old Carlyle Moritz may be growing it's round up ready canola without a licence.

Private investigators for the company took samples of canola near Moritz' land last week.

Monsanto says the samples have been tested, but the company will not say what the results are.

Moritz however, adamantly denies growing the genetically modified canola. He says Monsanto is using him to get back at Schmeiser."Being that the fact that I testified for Mr.Schmeiser, it's possible Monsanto are just trying to get back at me or get back at Percy though me."

Monsanto says it's investigation of Moritz has nothing to do with Percy Schmeiser.

Schmeiser's two-year battle with the bio-tech company drew international attention.

Earlier this year, a court found that he had violated Monsanto's patent by growing it's canola without a licence.

Monsanto says that ruling will make it easier to sue other farmers who violate the company's patent.
