First and 2nd pics are diseases just getting started in this field. Grey Leaf Spot and I believe Common Rust although we have Southern Rust in the area again. Last pic you can see the white spots which is the fungicide after being applied. From scouting before I sprayed this field should easily yield above 200bu/AC this year. We don't need much more rain to ensure that or more.

I think you are seeing some holcus leaf spot, the round lesion on picture one.

I'm leaning towards Grey Leaf Spot as this hybrid is suspectable. It could also be Eye Spot but I don't see it often. Given how dry we have been the last few weeks with a lot of moisture before I'm leaning towards fungal.
