in most scenarios before I can sell you corn you must sign a document stating that you cannot keep seed and you must be a certified licensed applicator to be able to buy Roundup. If you decide you want to save RR ready seed you will be charged a penalty of the technology fee which might be a hundred thousand dollars a bushell. This is not necessay each time you come for seed but it has to be done prior to the sales taking place. It is not worth the price for them to bother with it.....
