Roundup. Redrill.
Pre-em might work/help. I’m assuming it’s too late for that. If so you might be surprised how the barley will smother a low/medium BG population.

axial?
How lucky and rich do you feel? Have had acceptable results in the past but not reliable.

Did you drill it too early? I know hindsight is wonderful.

How bad is the blackgrass? You've got maybe a month at most to decide before the blackgrass comes into ear. If it is that thick you are getting a definite yield loss, you may wish to spray off some patches.
Start planning your next few moves now.

Rouge or roundup....
Just need to keep it at a level. If you are in a blackgrass area and want to completely clear it up it will never happen economically.
you can grow profitable rotations that Keep blackgrass at a okay level. It is so adaptive that whatever you do it will catch up.
repeated spring cropping just selects for spring germinating BG.
We have second wheat that will look messy, it won’t win a crop competition. But it will still make masses of money and will then go into spring barley next then probably spring oats after. In hindsight should have planted it but hey ho, cheap fert and can grow low N requirement spring crops on those fields for the next year or two while prices are high

I just redrilled a field last week as the barley was only at 2 leaves the slugs had been a pain in the @ss and the Bg was too thick for my liking, with everything else looking so well I though it was the right time to nail it.
