Spring crops following AstroKerb treated failed rape

[ConanPB]

AstroKerb applied in mid November.
Was considering spring barley Fss as a lower risk option.
Would Linseed fall foul of the "Astro" element of the chemical, I think this is more persistent than the propzyamide part that is more soluble.Would like to avoid ploughing if possible as on heavy clay.Maize another candidate.
any experiences? Thanks

Have done barley twice after Astro, agronomist seen it done many times.
In my case straight in with a Claydon.
Agronomist has never seen SB fail after astrokerb, but you are on your own,...no guarantees.
Clay soils.

Should be no issue this year as plenty wet after AK applied, to take it off soil surface.

Thanks for the encouraging s.barley replies
Any one with experience with linseed in the above situation ?

Sorry no experience.

Of course as well as it having been wet it has also been unreasonably warm lately, well south of the Wash anyway, so that won't help the AK remain viable either.

Again no guarantees, but if there was ever a year to get away with it then it must be this year.
I would gamble it, especially as your AK was november applied.

But i take risks some others would not.

Astrokerb label;

This is from the straight Kerb label:

Perhaps a call to Corteva's technical helpline is worthwhile? They will be a little cagey about giving out advice when it's not on the label but perhaps what they don't say might give you a clue. You just have to ask the right questions!

Linseed is flax family which hasn't been referred to above - this may be because it's not affected or because they just haven't tested it.

I've sown spring linseed after Kerb before and not had a problem. What worries me is the persistence of the aminopyralid, though clopyralid is approved in linseed & is closely related

 

[ConanPB]

Nobody manning the helpline but have left a message , will post any advice I can glean !
Thanks

The main threat comes from applications in the New Year. November application followed by a mild winter would make it considerably safer. (Soil temperature, not rainfall disperses it.)

I know of a few crops Spring Barley in past three years cut in with vaderstad where rape has failed following application of Astrokerb. No experience of Linseed. As ever, at your risk and no guarentee with my comment. Just a bloke on internet here. cheers.

Of course anything we do is at our own risk, just trying to gauge peoples success in the same situation.
At the moment there aren't too many major negatives, time soon running out for spring barley planting though, and tbh more concerned with the lack of rain forecast as regards establishing a spring crop, we have plenty of those needing a drink soon as it is !

We’ve drilled spring beans after failed rape sprayed with astrokerb, just ploughed it first and had no problems.

 

[They see me rolling]

Linseed will be OK if planted after Kerb/Astro-Kerb with the following conditions:
-In our experience Kerb applied before Christmas linseed will be fine
-After January do not sow linseed

What’s the risk of a end of January Kerb and a winter cereal crop without ploughing?

When have people had kerb residue issues?

December applied Astro kerb has had no effect on may sown spring barley, in fact it looked better to the line than the bits that were ru off before drilling . Drilled wheat loads of times after late application with out ploughing both strip till and min till .

But if your ww crop fails I’m not paying you out! As if they would anyway

 

[ConanPB]

No visible effects on our min-tilled spring barley after dec. applied astrokerb, same as above.
You should be fine

Shouldn’t be a problem. Many have done this, even no till drillers. Kerb breaks down with warmth and sunlight. Plenty of that since January.
