Northeast Louisiana | If we shut down at 90 degrees here, we'd never get anything done. I like to let the dew burn off first. Which means mid to late morning with our humidity. By then its usually in the 90's in the summer. Doesn't seem to have affected our control. I've heard that it's not good to spray late in the evening, but we do it all the time, especially in the spring when it's windy. But honestly, I'll spray from daylight till dark if I have alot to get done. It always seems to work fine.
Now if the plants are really dry and not actively growing, that does affect how well glyphosate works.
