At least 360 g plus either defy or avadex is the norm here, 240 not worth bothering really! And plenty of water as mentioned above

Bumping this thread back up now the BG will be flowering!!
Really happy with control here this year and the first time since it's launch 15 years ago that I've not had to use Atlantis/Pacifica, a real milestone and a good step in the direction I'm trying to take.
However....
The worst two fields on the farm are back in wheat after an absence of 3 and 4 years, the 4 year absence field was actually written off in 2015 and the 3 year one had a 40% yield hit in the worst areas in '16, this year both fields are spotless, but some pics of an untreated area around #BASF's excellent new herbicide trial plots shows what the residuals are doing in the 3 yr field, drilled Oct 25th.
So 3 lessons,
1- the measures I've taken are looking effective
2- residuals are working, contacts are resigned to history
3- I'm only one step away from a mess!!
Late drilling is working, but without the residuals it would be a mess, drilling later has to be tempered against the risk of not completing the full plan.
What lessons have you learned this year???

It's starting to appear now. Not just here but all around now the heads are out. By my own admission the worst fields are all after osr which I usually plough after.
Best fields are actually the winter barley that were osr until mid October.
The level of BG and lateness of drilling is not as apparent as the gap between last cultivation and drilling. I mean, the fields with the shorter time between making the seed bed and drilling are the worst.
Lesson - make seedbed finer and faster. I'm talking solo or whatever, power Harrow and rolls in the same field on the same day. Roll it tight. Shut gate. Come back minimum six weeks later. It needs to look as if you've just planted a new grass ley.
Drilling very late is not working for me as the fine seedbeds , cold clay and spindly sad wheat plants don't compete in autumn and are too slow to get away in spring .
Biggest lesson is you can't win. Worst field this year is after linseed in which you couldn't find a single plant last year. It's just undone seven years of hard work on that field so what can you do? Sigh.

Blackgrass is a good farmers weed. Crop failures etc and sprayed off and started again or whole cropped now and then are good for control where wall to wall 4 ton crops of wheat are its friend

Feel for you there @teslacoils, I had a spotless field of osr in '17 which lead me to break a couple of rules which lead to a mess last year, albeit one which yielded well...
I'd agree on the gap between cults and drilling, bit think shallowness is essential.

Our control is better than expected although the odd patch small patch will need spraying off. Last year’s dry summer and autumn facilitated good seedbeds which help control enormously IMO. Not sure what can be “learned” other than dry weather is better than wet weather, I knew that already. I will conviently gloss over the fact that C max is no longer as effective as it used to be!! I wouldn’t grow OSR without kerb now.

It's highly annoying, however the wheat crop looks the absolute business. The problem now is that so many other crops are simply not worth growing. The barley looks ace but at current prices it could be a waste of time. So all this idea of fixing it in the rotation is academic if the cleaning crops don't pay.
So out comes the baler, Mr Plough, then power Harrow. If it turns too wet to give it 8 weeks to green up then it gets left until spring.
I'm mentally focussed now on 1/3 to 2/5 of the farm in silage leys now, with as rye, stewardship fallow etc making up much of the rest. And cut costs accordingly.
You can see each field where the wide tyres cut into or picked up soil in fields with a pdm top-up in winter.
The fields which were osr had an exceptional kill. Really ace.
Should be noted that I don't have any other weeds but BG, so it could be much worse.
Still hopeful I can get 150ac rogued before Lincolnshire show.
I'd go so far to say that, if I can get this grass to work out, I might drop wheat *gasp*. If I had a larger ballbag I'd be chancing late November spring barley given how ace the volunteers in my (new seed - thanks for that) winter barley look.

Can it escape being cleaned out of seed sample ? I guess it can

Would broadcasting help for a more comprehensive..and quicker cover , .. is it more of problem of problem in wider drill spacing?

@Bury the Trash
Your user name may appreciate that, in a field I walked pre rain, the only bg there was coming up from under the epilated roots of the previous osr crop. Hence I like to plough the rapeland!
Broadcasting would be too risky given the doses of chem. Certainly I want it pretty deep for the avadex plus huge flufenacet dose we are on.

Of course I forgot pre em use.
So maybe if that was the case and in the absence of osr it would like to hide under the roots of late sprayed out charlock .... I suspect its spreading further afield... .

@teslacoils how much flufenacet are you using?
@T Hectares What’s the new herbicide?
I presume its Luximo, grass weed pre-em with new mode of action.
When you say no till how are you doing that? Machine? Rotation? Etc
Strangely our worse field is one that I thought was pretty clean a couple of years ago but had a bit appear last year and Atlantis didn't do a good job so put some grass in part and spring oats in part, the grass was a mix of westerwold and some longer term bags I had left over, either I didn't mix the two as well as I thought,although I cross drilled it but the westerwold seem mainly in one area and have swamped the by whereas the by has swamped the long term seeds, just waiting for the by to set seed and then will now it before it becomes viable as once seeds have set the by will die, I see several round here have already cut their new leys used to clean bad fields, the by will now regrow and likely drop see before 2nd cut, it's a gamble waiting for the weather as one it had to be cut between 20 may and 30 to kill it before seed becomes viable

It's not really new though is it. Just.....forgotten.
