I'm glad you said it Im fed up of the damn stuff too. It's turning into an epidemic thanks to the lack of chemistry due to the EU registration process.
Have got to say if you can rogue the bg you really haven't got any.
Hand roguing blackgrass.

Soon will have if you don't rouge it, give it 2 years

I hope roundup ready crops are confined to the dustbin. That is definitely no way to go, unless we want roundup resistance weeds!

Yep, it's like a lawn in places, and I sprayed those parts off where possible. Roguing is hopeless unless you've got one or two here and there. There is always such a massive leafy base on each plant that the bag fills up too quickly unlike wild oats which just have a few tillers.
I've a spray store full of useles chemicals like flufenacet, diflufenican, Defy, Atlantis, Broadway Star, Axial, Orama, etc. Cost a fortune and you might as well P on it.
For our infested field it will go in with under sown spring barley then be left down to grass for ad infinitum. Will ranch my herd of easy care semi wild cattle on it, and pull out a fat one now and again. Done with high input farming.

So what is the way to go?

So spraying of several chits of blackgrass won't produce roundup resistant weeds? Really?

What rate l/ha do you spray at in say rr wheat. Just think that f using a good dose it may not get resistant ? If using low dose on big plants is asking for trouble maybe.

Afraid it's varied spring crops, grass, roundup on small blackgrass etc.

You are spraying v small blackgrass. With RR crops you only supposedly get one hit of glyphosate so it's always left until weeds are big and start to compete.

Not a daft point at all.
Would be good to have a low tech tracker of where BG was in the spring, to monitor any Autumn chit from surviving rogues.

This Summer I've been roguing bg in some headlands; along one border I found mid June 2020 that some rabbits/hares had been munching. It was noticeable how the bg flowers were nibbled (in preference to spring-sown wheat) and how many single, newly growing bg plants there were.
Is it possible that the digestive system of rabbit/hare can cause a 2nd generation of bg within the same year?
I think its probably coincidence but I may well be wrong.

We already have roundup resistant weeds
we have used herbicide resistant crops since the first chemical weed control
Avadex resistant crop ect ect
we also have herbicide resistant weeds
8 days doing 20ha must be pretty big burden?

Yeah, I want to be doing am acre an hour. I do the easiest bits first, and encircle the worst bits over time.

Once rogued a 20 acre wheat seed field where after aimed to the wrong cane with the dicurane took 2 of us a week to rogue wild oats was before pre em markers after that had 2 Different coloured canes
bg was very rare in those days as ctu was very effective
should have kept it out with a better rotation which we now do
The only way I can keep on rogueing is to remind myself how much it will cost just a few years down the road to spray - if an effective one is actually available - and that I will have to shift to spring cropping for several years on half the farm. Mentally calculating the likely total cost of chemicals makes me sweat and keep going.
must have cost atleast £150/ha to have five people doing 20ha over 8 days if using agency labour

So equivalent to around a little over a tonne hectare of Spring Barley. Accrued towards the net margin over the rotation for that field. So for most folk a Spring Barley crop is a more cost effective route to managing the population of blackgrass in an individual field than hand roguing.
