Isag - the plots have combined acreage of .7 acre. I went a bit heavy on the Glyo at 28 oz. to 15 gals for these plots,
28oz on .7 acres is about a 1.25 qt/acre rate. That is still on the light side no matter how much water is used to deliver it. Yup, sounds like you did not have all RR corn on your first planting.
I used a 2 qt per acre rate on both RR corn and RR beans with out a hint of damage. Now I am trying to get ahold of some Ammonium Sulfate to add to the water prior to mixing glyphosate.
