Is your corn purple?
As I have been out looking recently, I have seen some purpling of corn plants in the fields. Did you know some of this is natural and good? Some hybrids have a normal purpling to the leaves due to genetics, and as researchers, we take notes on this. We feel it is a good trait to see as some of the better hybrids genetically do this and the purpling disappears quickly with no damage to the plants.
