This is a much greater distance than had been found in previous studies. One reason is that the sample used was much larger (400 acres with thousands of plants). Given that once GM crops are actually used in commercial applications they are grown in much larger numbers than in scientific studies, there is reason to doubt that the conventional wisdom on how far altered genes can spread may be unrealistic. Indeed, according to one scientist quoted, this is the first realistic study done.
Combine this with the fact that commercial growers will hardly be using the rigorous growing regimes used in scientific test sites and we have cause for concern. While the article indicated caveats, such as bentgrass genes being more likely to be excessively mobile than those in standard GM crops like soybeans, it is a timely reminder of the unknown dangers that biotech and agribusiness corporations are inflicting on us and our planet in the name of profit. Once out, this particular genie may be impossible to put back in its bottle.
But surely this is worth it to feed the poor? This GM grass has been produced by Monsanto and another company called Scotts for use on golf courses and it is resistant to Monsanto's herbicide Roundup. Are they trying to combat world hungry by feeding the poor golf balls?
