What to spray on Orchardgrass?

I'm needing to control some broadleaf weeds in an OG field. Second cutting was made 12 days ago and I figured I would give it another week to recover before spraying since we've had hot weather. It had fertilizer applied last week.


Now for the problem, my neighbor has soybeans within 100 yards of the OG so I don't wanna spray any 24d or dicambia. I also would like to spray something that won't stunt the grass too badly in hot and possibly dry conditions.

What do you guys suggest?
