Sunflowers and Kerb ?

[Clive]

I have a 12m headland about 200m long in a winter OSR field where due to water etc there is only really half a crop

I'm thinking of planting a 12m strip of sunflowers that I could harvest to get enough seed for use in future cover crops. It's also near my house so will look pretty !

Trouble is that headland will have had kerb back in early December - will it kill the sunflowers or am I ok ?

I’d give it a go. Don’t know for sure but Kerbs weed spectrum for broad leaves is quite narrow.

Dow label says wait 40 weeks and (sorry) plough (cough). I'd have thought either would suit, not necessarily both. On the other hand it's in the 'any other crop' section which means they don't know.

don't have one of those plugh things ! but maybe a pass with the carrier might be wise ? or don't bother at all as they will fail ?

Cover it in FYM and plough it nice and deep and you should get a good crop !!

Isn’t that just a label thing? I think sunflowers are in the same family as lettuce which needs 0 weeks after application of Kerb.

Asteraceae also include artichoke, daisy, echinacea, dandelion and many more.

Plenty of sunflowers min tilled in france , sown with a maize drill , not sure they spray it at all it's a cheap break crop .

As suggested above, Sunflowers are not on the Kerb label in the UK (either as a target crop or succeeding crop), and sunflowers are grown a lot in France.
I can't find a pdf label for Kerb in France, but they are listed as a target crop on the product page- http://www.dowagro.com/fr-fr/france/produits/herbicides/kerb-flo, and the following distributor leaflet gives a bit more detail, saying it should be applied before cultivation- http://www.lbagri.fr/client/document/kerbflow_51.pdf

Therefore, I would cultivate and crack-on

Good few herbicide options for sunflowers as I understand it.

There is a few, but not a massive amount. The following is a list from France. Obviously there is no guarantee that any equivalent UK products have sunflower use on their label or have an EAMU, and I am not making any recommendation

.... hear no evil? not if I hear/read some of the comments on TFF
... do no evil? mmm, maybe not

Did trials many years ago and used pendimethalin, worked fine.

If the land is heavish and not running sand the effect of the kerb will be less plenty of weeds germinate in the spring after kerb if there is no crop competition wild oats black grass that are target weeds
