Track Southern Rust being reported and see how close it is to your corn field by using this map.

Only one more corn plant emerged over the weekend - yellow flag was emergence on Day 3....emergence was pretty uniform with almost all plants coming up on the first or second day. There were a few skips. We will see how these plants mature over the season!
It's wet out here, but the corn emergence demonstration is well underway! Orange flags are first day emergence, green flags are second day. Stay tuned to see how many seeds emerge over the weekend!
