- Late-Season Roundup®. There is the risk of potential crop injury from off-label, late-season Roundup® brand agricultural herbicide applications. Drop nozzles should be used when Roundup is applied to corn 30 to 48 inches tall. Roundup is not labeled for corn beyond 48 inches in height due to the potential of poor kernel set. Always read and follow pesticide label directions.
- Managing Biotech Corn Traits in 2010. As field season approaches, there are several aspects to keep top of mind regarding each field. While not all inclusive, some of the most important issues are herbicide tolerance and insect protection.

- Grain Drying & Storage. Dr. Ken Hellevang, Extension Ag Engineer at NDSU, recently spoke at a series of seminars sponsored by Gold Country Seed. He kindly agreed to share a copy of his presentation. It covers how to reduce grain drying costs, grain storage recommendations, natural air drying, a comparison of dryer systems, and much more.
- Grain Storage Concerns The conditions that the 2009 crop was exposed to may predispose it to grain storage issues. Checking bins regularly will be critical to help minimize losses.
More Information
“My DSM is friendly, helpful and always has current information about what is going on out in the field. While on vacation with my family, my DSM called to let me know that I had some corn that needed to be sprayed with fungicide. We were able to make a few phone calls and get it done. Had he not been watching for us, we wouldn’t have gotten the field sprayed at the right time.”
