What have others successfully grown when OSR has failed after receiving Astrokerb?
Would cultivation be better than DD?

Corteva say no to everything apart from spring OSR if you speak to them. S Barley seems to work if direct drilled with minimal disturbance to a good depth below the propyzamide layer. Personally I’d wait as long as possible to allow the propyzamide to break down as much as possible

Used cereals before. Mainly Spring Barley. But seen Spring Wheat. Cause of failure? Seeing several fields South LIncs area with flea beetle larvae damage where I expect the field will be written off in next three weeks. Really irritating when the 2022 crop sailed through with minimal larvae damage and the crops established satisfactorily Autumn 2022. And these crops being taken down were large biomass before Xmas. Just a risky crop. Hey ho.

Fallow it. get nearly the same goodnes to the soil without the next years slugs.

Did this a few yrs ago. Disced it twice then drilled a summer cover in May. Was like a rainforest, then had the best wheat following. Expensive though.

The only time I had this situation I cultivated it and planted Spring Oats
They did ok and made a margin, spread sludge on the oat stubble and grew a first wheat as good as anything else on the farm

Really? I've had poor wheats after fallow. The soil was dead without any plant life. I'm with Wigeon on this. Leave it then cultivate and establish a cheap cover crop through the summer to keep the worms busy and to have the take-all break.

Can you remember what was in the rainforest mix?

From memory:
Phacelia
Japanese millet
Vetch
Berseem clover
Plus others I cant remember.
Came from Hutchinsons and was called maxi summer cover, or something like that.

If you do this, don't be tempted to drill too early, otherwise it'll run to seed too soon.
I didnt spray it off but topped it in front of the shakeaerator. Felt bad topping it as it was absolutely alive with bees, but didn't do it all at once.

Just found a photo.
It also had buckwheat and mustard in it.
Re aminopyralid, I think it might have affected clovers and vetches a bit.

Have had multiple people grow good crops of Canary Seed after this, cultivation to brown and warm the soil and increase the breakdown of the residue then drilled mid April, never seen an issue. GM's make sense this year with av. crop yields of 2-2.5t/ha linked to fixed contra's @ £550 p/t. Pays far more than a fallow/CC and makes use of any N/S/P/K already applied.

Does any care need to be taken with the straw of a replacement crop? I seem to recollect that astro kerbed osr straw shouldn't be baled to avoid the tainted muck getting near a susceptible crop (spuds?).
Same reason why one of the grassland products (forefront?) is/was only approved on grazing.

Anyone grown sugar beet after failed rape thats had Astrokerb on it ? Deep ploughed possibly? Thanks in advance
These screenshots from the Astrokerb label suggest that straw & residues be treated very carefully. The fact that fat hen is controlled suggests that other
Chenopodioideae like sugar beet might be susceptible to the herbicide residues. No doubt someone will say that they've grown X, Y or Z by DD after Astrokerb but legally, you can't and should be ultra careful with any broad leafed crops soon after this treatment.
