SUs have good activity but need a robust dose even if mixing with Starane, CMPP etc. Arylex products (Zypar, Pixxaro) have good activity also.

Ally and a 1 litre of duplosan when it is warm.
Yes been steadily increasing since triflurlin went. It’s a pain but we seem to control it in the crop but it’s increasing.

There are several problematic broad leaved weeds that have steadily been slipping the net over the years. Mayweed; bloody stuff seems to be an ever more omnipresent in every field despite the stacks of autumn treatments that go on, then there is good old cranesbill and also there is that weirdo grass weed barnyard grass which seems to be appearing in places it shouldn't (I blame maize cultivation for that).
The latest Dow chemistry arrived just in time although to be fair SU + hormone chemistry sorts a lot of stuff very rapidly.

Whack it early with full rate ally max and starane while it is still a seedling. Then glyphosate any bad patches before it sets seeds.
I think the problem is it can grow back from the big tuberous roots once they get established. If sprayed later in the season the SU mix will knock the top growth back looking like it has killed it, but it then grows back from the root, unseen in the cereal canopy until it then pops out late on and sets seed before harvest.
Its a very expensive weed to control and it needs getting on top of before it gets everywhere.

I'd echo the above comments with the addition of Broadway star for control.
The issue is that it seems impossible to control in OSR...

Belkar may provide some relief in OSR. Have Burr Chervil - another annoying umbelifera and at moment am seeing some quite reasonable activity from December applied Belkar. I watch with interest.

Belkar has one of the actives of pixxaro from memory?
Broadway star is a weird one, does some blws but not others.

It will be interesting to see how Belkar performs, Astrokerb and Galera all hit Wild carrot hard, but it always bounced back eventually.
Arylex didn't hit it in Cereals...
I had big problems with Wild Carrots in my onions last year, never seen any Wild Carrots at all before that. Since we only have 4 herbicides to choose from there was not much I could do expect try them all. But I can at least tell you that Boxer, Fenix, Lentagran WG or Buctril EC 225 did not do much harm to the Wild Carrot, at least not in the small doses which are allowed in onions in Sweden. The combination that made most damage (a few leaves on most plants changed a bit of colour) was 0,17 L Buctril EC 225 combined with 0,33 kg Lentagran WG.
