How can I handle the risk of cross pollenation from neighboring fields?
This risk is mainly for corn, and is one that cannot be completely eliminated. You may want to contact neighbors to find out what type of corn they will be planting in fields bordering yours. Also, check with agronomists to determine how far into your field there is a high risk of cross pollenation, and plan to harvest and feed or market this portion of the crop as GMO corn if it borders a GMO corn field.
