Ben Taylor-Davies black grass talk

Yes it can be .
Could be the ultimate heavy land year next year given soil structures atm

Especially if roots avoid being waterlogged overwinter. At depth our soil is still pretty dry.

We have a few BG plants here but they do look dickey... hoping they die(some will) and no more come up, will look again in the new year.
With the warm weather forecast and good field conditions its tempting to go with Pacifica.

More field walking today. I think I am disappointed with BG control overall thus far. Maybe some will succumb to existing applications, but if not there's enough there to generate enough seed return to be a problem. Going to do FFCT, PDM (+ Atlantis) top-up tomorrow over 20-40% of wheat area.

Similar here except much of the worse BG is in winter barley so not much in the way of follow up options......

At least you can't worry about what else to put on. Hopefully crop competition will help there. I'm getting more and more cross about our drill bout mismatches as that will let the weeds through.

bg here is heavily affected by pre ems
I cannot say it has failed on any field yet as it does take a while to kill the bg a sharp frost before December would help a lot
bg at 1 leaf does not cope with frost once it has tillered it can take a lot

Ours is more like average 2 leaves with some at 1 and some at 3 leaves. Some looks very sick and others look quite happy.

I think low seed rates with hybrid barley are not helpful at this stage. BG already seems worse in any drill misses here.....

Can someone tell me the life span of a pre-em when applied on warm soils late September/October or colder soils late October/November.

I guess (as in just made it up) that it would be up to 50% longer at the later timing, but I may be way out. All residuals have a different half lives that vary quite a bit and I don't know the standard conditions used to calculate them but they are available, i've seen slides at a NROSO course.

Not sure if I'm over-reacting or not, but Jon Cussans' work on eventual seed return even from low initial plant populations (but with high tiller numbers) means I think I need to do something. These fields are planned for fallow next year so I'm just not sure how much BG seed I can comfortably let through.

My observations with hybrid barley was that it came into it's own later on in the spring but wasn't very good in the early spring / overwinter when the black-grass starts to get a wiggle on. In the year we grew it I liked the thicker plant stand and earlier canopy closure in the spring of the Glacier.

Surely you can let more go with a following fallow?!

I want to use the fallow to really clean up the ground, rather than as an excuse being being slack on in-crop herbicides and end up just treading water. That said, I'm still not sure whether what I have is enough to treat. From fields that I didn't quite treat last year and which I then thought I should have done, these are worse, and so I think I need to.

Weather (radiation levels) between May 15 and July 14 next year will determine yields on moisture retentive soils. Look of crops today is for the farmers eye only. Beauty is in the eye of the beholder.

Fallow won’t benefit you in any other way though, can you not grow something to break the residual cycle

We're committed to fallow through upcoming Mid Tier agreement.

That’s fine i just wondered whether you thought it was the best approach?

Is this all after OSR? Can I ask if you've done any very shallow tillage/ no till into OSR and if is any better?

I presume if you've done some deeper tillage I presume these are the plants coming from deeper down having been "activated"?
