Sunflower disease outbreak?

I am starting to receive reports of higher than normal diseases levels in sunflowers. I looked at several fields last week and didn’t notice anything untoward, some grey/brown lesions on the lower leaves which was more than likely abiotic caused by water on the leaves and bright sunshine. Mind you with the wet and warm weather we have been having this month it would be surprising if we didn’t see more diseases developing. I will be looking at sunflowers later in the week and report back.
