How do you kill chicory in spring barley?

[Brisel]

As per the title really. One for the agronomy geeks! @Ugo79 @richard hammond @Bogweevil @BenB - I've has a discussion with Nick.

I have a couple of ex AB9 winter seed plots now in spring barley. Despite a good dose of glyphosate pre drilling, the chicory is coming back and will soon be competing with the barley. The chicory is in the late rosette stage and the barley is in the late stages of tillering. The following crop will be winter beans but the straw will be baled.

My agronomist thinks clopyralid as in Shield (limited dose only) or Dakota with fluroxypyr and florasulam. I've spoken to the area agronomist for FMC Headland & he thinks Harmony M will do it if the plants are soft. Chicory is a member of the compositae family. Recent rainfall means the chicory is still quite soft and not well waxed up.

These are only small areas so if I go down the route of clopyralid I'll fallow them instead of risking sowing winter beans. A "normal" T1 fungicide pass on the spring barley would be based on EC fungicide Harmony M + fluroxypyr (+ CMPP if fumitory is present).

Based on this old Dupont data I would go with an SU...looks like it it sensitive to all the different SUs.

Have seen a document on Corteva website r.e. game cover and they recommend not using Dow Shield or Thistlex on covers with chicory.... suggesting clopyralid will have some effect (lethal?)

Don’t ask me about the agronomy bit because I’m rubbish at it ? but I’ve found Pennant to be quite a bit cheaper than Harmony M ?

Thank you @Ugo79 @cricketandcrops

Strange. It contains the same doses of the same ingredients as Harmony M

Exactly the same just smaller container, 250g instead of 400g, was £31.25 a kg price difference though on the quotes I had.

Chicory is a pain in the arse to get rid off

Which herbicides leave it alone as I use it in game strips but would like to control weeds in it

 

[Brisel]

What weeds? I’ve used graminicides successfully, otherwise it’s spot treatment with glyphosate for spear thistles.

Some plots have lots of thistles rose bay willow herb fat hen
grass weeds not too much of a problem
new plots much less of a problem

 

[Brisel]

I don't think there's much you can do other than spot treat with something non selective.

I have seen MCPA and 2,4D knock chicory from drift.....
