Many corn growers in the Eastern Corn Belt produce NON-GMO corn attempting to capture an additional premium. Depending on the contracting elevator, standard GMO contamination allowances are typically from 0% to 1%. Producing NON-GMO corn within the acceptable tolerances of GMO contamination is possible; however, there are several challenges and potential pitfalls that make production of 100% pure NON-GMO corn a tremendous undertaking and can keep growers from capturing a premium for their corn. Planting NON-GMO seed does not necessarily mean the harvested shelled corn will be NON-GMO free. Tests used by elevators to determine if GMO’s are present may not be 100% accurate, but they are a determining factor as to whether a load will be accepted.
If a grower plants NON-GMO corn, what could cause GMO contamination?
• Contaminated planting equipment and seed tenders
• Contaminated seed
• Mistakes made in record keeping where hybrids were not correctly identified at planting and/or harvest, leading to contamination
• Adventitious pollen from GMO corn fields can cause cross-pollination of NON-GMO corn
• Contaminated combines at harvest
• Contaminated grain carts, wagons, trucks, augers, grain legs, and grain bins
What steps can be taken in an attempt to produce grain that meets GMO tolerances?… Continue reading
