Profile: Leon Perehudoff

Leon Perehudoff was a participant or observer in the following events:

Aaron Mitchell, Monsanto’s lead investigator in the Percy Schmeiser case, obtains a back-up sample set of the canola pods that were collected from Schmeiser’s property the previous summer (see August 12, 1998) from James Vancha who has been storing the pods in his freezer. Mitchell takes the seeds to Leon Perehudoff of Prairie Plant Systems who assists him with the grow-out test. Perehudoff will later testify in court that the seeds he receives are clean, though the original sample set of canola pods contained debris. Mitchell claims that he cleaned the seeds by hand even though there would have been no reason to do so in order to grow the seeds. When he is later asked in court to explain how he did this, he will respond that he did it by hand and that it took him about an hour. Another witness, Lyle Friesen, a plant biologist at the University, will testify that the task should have taken “days” to do by hand. All of the seeds included in Mitchell’s grow-out test germinate despite the fact that neither Monsanto’s St. Louis lab nor Friesen (see (August 26, 1999)) are able to so because the seeds were improperly stored and/or moldy. After the plants have grown, Mitchell takes them away to spray them and then later returns with them so he and Perehudoff can count the survivors. For one of the samples, he records an impossible survivor rate of 106 percent—there are apparently more plants in the sample after the spraying than there were before. He then averages this percentage rate with results from the other samples to come up with an average survival rate of 92-96 percent, which Monsanto will later cite as the percentage of Roundup Ready Canola plants in Schmeiser’s 1998 fields. As Schmeiser’s lawyer will later note in court, the samples were not collected using a methodology that would have ensured that the composition of the samples were representative of the composition of the fields.
