Genetic drift is one of the most common problems organic farmers in the United States face. Recently, my husband Klaas looked across the road at our neighbor’s farm and said in a horrified tone, “You know, if Harold plants Bt corn on that field next year, we won’t be able to plant organic corn anywhere on this farm.” This sudden realization, born in the increasing knowledge that organic
farmers can no longer ignore the impact of their neighbor’s genetically modified crop varieties, struck us hard. We had thought that the neighbor’s corn pollen might affect a small portion of our nearest field, something that appropriate buffer zones would take care of, never really thinking it could render many downwind acres unsuitable for corn. But it certainly could. This is the reality of organic farming today.
The impact of genetic drift can affect my farm, my planting plans, my certification, my income — not on just a few rows, but possibly on many acres. The scariest part of this reality is that the farmer won’t know if contamination has occurred until it’s too late, and then there is relatively little he can do to prevent it. To be prepared for the 2000 crop, organic farmers must start thinking of GMOs as being their problem too.
