[Laggard]

A bit of Teb going in with ours.

How much Teb?

How much Teb?

0.35l. For phoma as much as anything. No fungicide to date.

What does control groundsel - we had some in a thin crop two years ago, and it would be helpful to know in future?

I think I started a thread on here about it and I’m blowed if I can remember the answers. Search it.

In what crop? Sulphonyl ureas and HBN in cereals. I’ll look up what hormones cover it. In osr there isn’t much. Arylex does it when very small. I remember Galera twisting it up well. Matricaria species IIRC.

in rape now. Aminopyralid - in Astrokerb. Or clopyralid - legal from March 1st.

 

[DanniAgro]

Thanks for the help - I meant controlling it in OSR.

Belkar gave groundsel a good headache last year and some I did on Friday afternoon was bending over yesterday. Last year the belkar and kerb mix gave better weed control overall here than Astrokerb. Most noticeable were poppies which were present at harvest in the Astrokerb treated crops. I’m using belkar mix this year.

Aminopyralid and clopyralid are pricey so if you can live with it, avoid!

Interesting that Belkar seems to control groundsel, at least in some degree, as its label does not mention it, and a company salesman I met at an open day last year told me that it definitely didn't touch it. That's what prompted my question.

Only at cotyledon stage really. By the time the crop is big enough for Belkar ie 4 true leaves the groundsel is too big

Got a small field with a nice crop of rape and some sow thistles making an appearance now what’s the best to tackle them with? Only had a whiff of falcon so far.

Aminopyralid (Astrokerb) now, or wait until March 1sr and use clopyralid.

Applied Astrokerb on Sunday and it has made the OSR “standup”, is this normal?

Yes I think it did mine the twice I did it.

Astrokerb applied 19/11/2020. Willow herb looks unaffected today 11/01/2021

Rosebay willowherb is a tough one, I've never seen it about enough to do much harm but it does want managing in following crops.

Groundsel- MCPA in cereals?

We have received anecdotal information back from growers that Astrokerb will offer control rosebay willowherb but do not have any specific information on size etc. For further information do not hesitate to contact the Corteva Agriscience hotline on 0800 689 8899.
