The corn appears to be healthy and growing well.
As I said in the previous post, 10 to 13 acres, out of the 61 I have planted to corn here, have heavy foxtail pressure and will have this kind of weed pressure. The remaining ground is relatively weed free. Aside from not killing weeds so they don't return next year, I might suffer a yield "drag" as the weeds take nutrients from the corn, limiting my yield at harvest time.
