So I picked up a quarter section of good grain land that's been in hay for 20 years. I split it up into 40ac strips, spraying it, then baling it 3 days later to maintain hay quality.
With all the rain, this was done over a period from July to September.
All of it was done with the same NuGlo herbicide @ 800g/ac, 4GPA water, 20 on the Magnahelic (same size droplets). Always sprayed early morning, always at least 24 hours of rain-free weather.
This is the field that was ploughed 20 years ago and too rough to notill.
The stuff done first week of July regrew grass-green. The old growth all died, but fresh growth came back.
The stuff done second week of July has less green growth, but thistles all grew back just like in first week.
The stuff done middle of August, is totally brown - dead - and the soil has somewhat softened up.
The stuff done at the end of August is totally dead also. The ground, however, is hard as a rock.
From this, I'd say that August 10th to August 20th is the optimal time to kill a hay field.
I didn't grab any pics... was in too much of a hurry.
Again, this isn't scientific, just general findings...
