Autumn herb options in absence of BG

[Flat 10]

What do people recommend?
I know years ago it would have just been a slug of IPU. Bearing in mind it will hopefully be reasonably early planted WB that I will be going through postem with Mang and BYDV (tin hat on) what would people use? Something like Tower (CTU,PDM + DFF I think). I expect there to be a reasonable amount of BLW's. Could just use a lowish dose of PDM + DFF. Just trying to make a plan.
TIA

Any ryegrass or brome? If not then the PDM+DFF sounds a plan. Cranesbill?

 

[Gong Farmer]

When's 'post-em' ? PDM and DFF need to go on a bit early, big established weeds might not be controlled.

I've been using pdm×dff since the ban on ipu/ctu. I've never been completely happy with the results, it cleans the crop up through the autumn and spring but often I end up with a few to many one eye daisy in the crop come harvest time that's a problem I never had previously.

This year I'm thinking of trying tower if nothing else just to break the relience on the same chemical year after year. Is the ipu product bluetron? Still available?

Edit just looked,bluetron max dose 1lt/ha I'm not sure 250g/ha of ipu is going to do much good☹

A new piece of land to me. So slightly unknown. From what I've seen charlock and thistles will be my main BLW's. Couch will be the main grass weed so round up will be dealing with that soon hopefully. Bit of AMG. Thanks for help everyone.

Lexus + Stomp ?

Lexus + Stomp ?

What will the Lexus be adding? (when I'm not going for BG) and pre-em only in barley?

 

[Oat]

Lexus might add a bit to Charlock/vol. OSR, Groundsel and Shepherd's Purse control, above that from Stomp

 

[david]

AMG and BLW control with the Lexus.

 

[shakerator]

Nothing. Get a healthier plant over winter then tidy up in April

By letting a few controllable weeds grow over winter you are stopping nutrient leaching imho

Crop competition isn't too much of an issue imho at that time of year. The wheat grows prostrate even with matts of BLW around it as sunlight energy is low

Blackgrass however changes it all

What other weeds have you?

If you have no nasty grass weed problems, use Picopro and be done with it. It wont stop every BLW but they dont really turn up until spring anyway.

Relying solely on post em products for weed control in ANY crop as a habit it a BAD idea because you will only encourage resistance to the more commonly used actives. Use all the tools at your disposal and try to avoid relying too heavily on them.

I personally would not dare grow winter barley without a pre-em or very early post em autumn treatment as you will have no way whatsoever to control grass weeds if they did arrive.

Groundsel (and some other BLWs). Maybe AMG if you are an optimist.

Groundsel in the autumn? I never find it a problem until early spring.

But it does depend on the weather at time of drilling! I agree the best ever timing is peri -emergence, by then you know you have a crop to spend on, and you can mix and match actives to suit the conditions.

I have some fields that have historically been laden with it. 10g of Lexus sorts it.

It is a sod of a thing in spring, particularly this one, when it took forever to die from the usual SU treatment. It did not help that we could not get near it until such time that it was monstrous in size.

If I knew I could get on every field at peri-emergence I would possibly do it all that way, it's the same with later BYDV applications. Often it just becomes impossible to travel. I'd rather get the pre-em on and wait to see what the weather presents, 99% of my stuff is Deter dressed and we only get BYDV sprays on occasionally.

A good portion of my stuff had no spring herbicide whatsoever this year.

Well done! no spring herb is impressive, did you have no late germinators after the mid May rains? I took out all my late weeds within rec with a cheap generic Ally(type) + Starane(type) after the rains. I will admit I have had a few more than I was happy with spring germinating Oats, was this only me?

More than likely there will be some weeds left in the stubbles, normally the odd thistle emerges or crucifer or hogweed but the crops were too tall (some were rather dense as well) to even bother with them, they were never economic to spray for.

Wild oats are a field by field problem, there are a few about, and looking at other people's stuff, there is an awful lot of pale yellow blackgrass swaying around having already jettisoned it's cargo.

I tend to get a proportion of fields most years that don't get any spring herbicide. If the crop takes off early there just doesn't seem to be any light or space for anything to emerge anywhere else.

I hate people who refuse to do anything in the autumn because you have to do the nuclear option first thing in March when it is normally too cold to be doing it and by that point the weeds are getting big etc etc etc. Nothing worse than having to get all the tools out up front. I'd rather wait for the BLWs so I can hit them a bit later when their spring germinating cousins have arrived.

I have rarely needed to use a spring herb since we have used a pre em and post em in the autumn. If we have needed anything starane is normally enough.
