I have some fields with very little bg that had more in the 90s they were the worst I had then
Double spring break crops reduced it then auto cast rape and wheat with crystal and antlantis then beans and crawler then double Spring crops very little in last years wheat but some in spring beans this year
No till wheat then rape the next crops
Looking at Spring barley Spring break crop wheat rape wheat as a rotation this will rotate crops cultivation and actives
I would look a Spring rape if it was rup ready and drop winter rape but grow winter beans with kerb and crawler

Wouldn't say bg free but to the best of my knowledge haven't let any set seed for three seasons.
Problem fields grass, grass, grass, w wheat, w barley rotation. ( normal fields grass grass s barley wheat w barley)
Sprayed patches off in the past plus a lot of rouging. Not had to spray any for two seasons and roguing getting less year on year.
Plough and combi for all cultivations. Stomp + herold pre em. Horus ( wheat) and axial ( barley) in spring. Haven't got any resistant bg and if my understanding is right as long as none sets seed resistance won't develop.
In my favour it was only patchy when I came here, not a total infestation. I am really a livestock man, if I was on an all arable rotation I don't think I would have been able to get on top of it. Grass and muck seems to help as much as anything.
Will i ever get rid of it? I'm not sure. The bloody stuff has a habit of appearing where I don't expect it. If I get a year where I don't have to rogue any the next season I will leave a patch unsprayed to see if any comes.

Ditto, now why is that? we do similar to the fields that only had a little to keep it out
No idea. Have two fields side by side after OSR. One was lightly disced twice, one ploughed, pressed etc. Drilled same day and same chems. One has barely a BG. One is very sad.
I'm taking this year with a pinch of salt because:
1) The number of BG plants is not high - but the tillers and ear size is making me sad. With the usual tillers and ears I'd be saying hey ho.
2) We only used a pre-em, and nothing else. Atlantis works here, and we should have used it, but walking the crops in Feb you couldnt find a plant.
At the same time, spring beans which are my hated crop have been ass to control BG in, yet this year some Avadex and Stomp has knocked it for 6. Cant find a BG plant worth toffee in spring oats.
Some things that are holding true:
1) The less we move the soil for OSR the better control we get. A deep tyne gives us more BG coming from depth, and a flush of BLWs. Scratching it in with the disc drill gives us very few BLWs and the residuals work loads better.
2) After a good crop, there is no need to work he land deeper than a couple of inches.
3) Spring oats are here to stay.
4) It takes 5 weeks from mowing grass for the next wave of BG heads to start flowering.
5) While Atlantis still controls cleavers and wild oats, its no dearer than starane + Axial, so it goes on in spring irrespective in wheat, and just grow wheat on a longer rotation.
6) Figure out how to make some dosh from grass.

Black grass is only a problem when it costs you. Same as wild oats, couch and anything else. The losses expected are here:
Like many weeds insects and life in general it will do its best to survive. It is just an evolving battle of controlling the latest upstart to a level where it is bearable, Some fights are never won and are an ongoing war. In the order of ease of destruction I would offer [but not defend] Vertebrates, insects, plants, fungi.
Fight the most cost effective fight for your farm at this time.

Same here with Atlantis , still works to a certain degree on some land on grasses but no need for any broad leaf weed or wild oat control after.
Birds as well I think.

This is so true as we do a bit of contracting I always blow the combine down when I have been in a dirty field. Also one of the reasons I don't sell any straw, keep my own fss seed too!
Went through some of our own osr the other night and although the field is clean ish there was some in the tramlines , the front of the sprayer had some on so again to blow down.
Dad thinks I'm mad but I want to put a small spray tank on the sprayer supplying two nozzles behind the rear wheels so I can treat the tramlines with glysophate, i was thinking after the kerb cmax etc around the time of stem extension? There would be no loss if crop as it would bridge over? But 95% of the bg in our osr is in the tramlines!
Are you sure its not 95% of the BG you can see...........

That's a fair point but I think it's mostly there. It's where the ground has been disturbed by the edge of tyres etc and the light can get in to allow it to grow. But I see you point and agree there is some elsewhere but as it's a numbers game taking these out must help?Are you sure its not 95% of the BG you can see...........

No what? Reducing numbers doesn't help?
