It's just the stuff doesn't rot away like wheat does.

There is some in the seed, have barley here in ground which has never previously seen wheat or barley.

We planted a fair bit here with a Vaderstad last week of October into lightly disced and sprayed off OSR stubble. ATM these fields are our cleanest but I'm wary the BG could rear it's head soon as the wheat comes into ear.
Earlier drilled wheat and barley is showing that we have a major problem now, time for a rethink...

All our main black grass problems come from OSR stubbles in the wheat the year after. We min till after rape I don’t dare plough it back under. We’ve used monolith if we can’t get on with Atlantis in autumn,as well as avadex and the pre ems. Seriously re thinking growing OSR we tried going back to commercial OSR instead of hybrids but to no avail.
We constantly use spring barley in the worst fields certainly makes a difference. Problem is our next door farms are rank with it, nearly unfarmable. So it’s growing round us.
Has anyone used Zirton, Fence and the new on Liximo? Someone I know has used these to decent affect with obvious Atlantis reistance.

I used xerton in a post emergence sequence. Did a good job. Hot on the wheat though. Pre-em was 3lt crystal plus extra ffu, then xerton plus pdm.

The key for me and it has been mentioned above is a strict quantity of time between last cultivation and drilling . So I shall be aiming to make as fine a seedbed as soon as any straw is baled and stubbles sprayed off. Whatever we use to work it will be chased by power Harrow and rolls and left be for a minimum of six week to two months.
Wholesale re think needed if you have bad BG, not just trying another chemical. 50% spring cropping, changes in cultivation (if any) strategy. Much later drilling or ultra low disturbance. Lower output of rotations that control blackgrass means you need to heavily re-think fixed cost structure to keep profit up.
I know this because we’ve had to do it!

Single spring crop much less use than a double spring crop. Trick is making those spring crops pay.

Its all over the SW. Contaminated seed.

Maize for you has to be a good bet.
The kind of soil that has a bad blackgrass problem is going to need some serious drilling capacity in the spring to do half the farm. Daily drill outputs are not the same as September & there's a lot of waiting for the land to dry out. You'd either need direct drilling or have all your soil preparation done in the autumn so you just spray off and lightly drill in the spring. The last 3 years have not been kind to spring crops down here. Wet in March & early April then dry afterwards.
Spring cropping is a good way of tackling the problem though, but only part of an integrated strategy.

I'm not convinced barley stops blackgrass, just because you can't see it above the canopy doesn't mean it's not there beneath.
If a field looked extremely bad now I would spray it right off now.
Follow with a fallow or spring crop. Probably maize in this part of the world.

Spring cropping here generally means start mid April. Drill for a week. Hope it rains. But not too much. Grass is a better crop. By better I mean more reliable.

I’ve found the same, and wild oats! Forget it
but I am glad it’s rogueable as few years ago it wasn’t!!
From past experience from topping blackgrass patches I would say yes it will regrow and head before harvest. There eould be a fair chance the seeds would be viable aswell

bring back stubble burning, never had this many problems with BG, brome or many other weeds when we burned the stubbles, never used as much chemical then either or slug pellets for that matter

Yup. The dormancy break of a good burn would be truly ace from time to time.

I might have had a little burn get out of hand year or two ago, just burning a small bale or two that hadn’t been cleared, took out about 10-11 acres, the osr looked fantastic in the burnt bit but flipping heck the blackgrass did too
