best spray for cleavers??

Capercaillie

Have to spot spray cleavers in a cover crop? Tried roundup and MCPA last year and virtually no effect. What would be an effective spray )spot spray? Thanks

If you are spraying at this time of year when growth is slow I doubt you will have any success with anything? When actively growing I find anything with 2,4-D in it knocks it over and has little affect on clover (in my lawn at least).

Going to try and spray in late March, when emerging.

Sorry read that as "clover"

I'd be worried that 2.4-D might have an affect on the Nettles roots even if they hadn't started to emerge in late March. That said if you got away with MCPA then I suspect that 2.4-D wouldn't be any worse on the nettles.

Most of the hormone type weedkillers won't have much effect on cleavers unless it's quite warm for a few days either side of application, by warm I mean tee shirt weather, but the nettles will probably be growing strongly by then and will be scorched by the spray. in this case the best cleavers product is Reaper/Binder/Hurler, next best probably CMPP.

In cereals the best cold weather product for cleavers is Boxer, it'll clean them out but you'd have to take advice as to what effect it would have on the nettle roots and any small plants emerged at the time of spraying.

In any case you'll be looking for an off label recommendation from a supplier for your records in case the Dept come calling

Was hoping someone else’s would ask.

What’s a “cleaver” ???

Don’t remember hearing that term before.

Is it ''robin run the hedge''

We used to use CMPP years ago to kill it in crops of barley

I'd call it goosegrass but Wikipedia says

Galium aparine, ('aparine' from Greek 'apairo' - "lay hold of" or "seize") [2] with many common names including cleavers,[3] clivers, "bort", bedstraw, goosegrass,[3] catchweed,[3] stickyweed, stickybud, robin-run-the-hedge, sticky willy,[3][4] sticky willow, stickyjack, stickeljack, and grip grass, is a herbaceous annual plant of the family Rubiaceae.

The stuff that kids pull up in the summer and try and stick to each others clothes.

Yea.
I get what ye are talking about.

Robin run the hedge is somewhat familiar from my childhood.

Thanks, great advice. I only have a small amount so will only be spot spraying. Don't want it spreading though or my whole nettle crop will be ruined.

Cover crop of nettles.

How does that work ?

Pre-spray area with roundup. Cover sprayed area at depth of 15cm with spent mushroom compost and rotted farmyard dung. Dig up nettle rhizomes from donor site and wash soil off. Break up rhizomes over mushroom compost/dung and then cover lightly with spent mushroom compost and roll. Spot spray for scotch grass, chickweed, creeping thistle and cleavers. Mow down in October and bale . In subsequent years fertilize with super phosphate and later in Spring with 10-10-20, while controlling any weeds by spot spraying.

And what are the nettles used for ?

Useful chart for anyone wanting to do some weed control if only from one company, Envy looks the part for you, it's a premix of the two products I mentioned above but again take professional advice since it's going to be an off label situation.

Whelehans who distribute the Dowagri stuff in Ireland are very approachable.

Now that's interesting, is that a private undertaking by yourself or part of a bigger scheme?

In the first link in the printout for the Control of annual weeds it says "label Weed". does that mean its not licenced for that use?

In NPWS Corncrake Farm plan. It's an agri-environmental scheme, something similar to Burren scheme.

Products are licenced for use on a particular crop, not by the target weed/disease, the label for envy is linked below, you'll see it's licenced for grassland use, so I couldn't (legally) use it on my wheat, even though it would do a job for me in some circumstances.

https://www.dowagro.com/content/dam/hdas/Dowagro_ireland/pdfs/envy1.pdf

In your case if the field is in your basic payment application as grassland then the label requirement would be fine, if it's in as anything else then you'll need to be careful. That's entirely apart from the effect that the product might have on the nettles....

Was looking at the "Envy" product and has only some control over nettles so might be the one to go with. I'll double check with NPWS though.

They'll probably have come across this issue before, best of luck with the corncrake project.
