Buttercup

[neilo]

He is coming back next week to do a couple more paddocks. I will try and find out but I am not sure he will tell me.

I'd be very concerned if a spraying contractor wouldn't tell me what I'd paid him to apply to my fields! Personally I'd have wanted to know beforehand, even if I had asked his advice on a suitable chem.

Re the buttercups, we've sprayed a grass field off with a good dose of glyphosate for reseeding. There's a few buttercups, how toxic are they when dying for cattle and sheep? Sheep obv graze them when thriving but are they toxic while dying? I'm not looking for "read the label" btw as the label tells you nowt really in this regard.

Personally I wouldn’t be too concerned about it. They aren’t ever toxic to the degree that ragwort is, and that’s only toxic in large quantities (as they might eat when dead & palatable).

Buttercups are only toxic when eaten green, when cut and wilted, or made into hay they lose their toxicity. An animal would have to eat a lot to be affected, and its highly unlikely to be fatal, the main symptoms are diarrhoea and an inflamed mouth:

Spray with at or nearly full rate envy, use an adjuvant. Spray now whilst they are growing hard. They will stop growing and slowly begin to fade away after 10 days. Correct fertility or pH issues in the soil also to encourage the grass to take up the free space.

I keep hearing that Envy is great for buttercups. We've used it twice now at either full rate or almost full rate with a litre of fluroxypyr. Really not impressed. Wouldn't be so bad if it was cheap and cheerful but it's not.

We've got a silage field to spray this week, is there anything better or am I going to be wasting my money again? Obv Forefront would be ideal but a no go on silage ground?

Try full rate MCPA on a warm morning when the field is yellow with Buttercups. It costs about £7 an acre and even if they come back slowly over the years it's cheap enough to go again and the clover usually survives too.

When was the envy applied?

Forefront is even more pricey than envy, this is your issue.

If you have used envy in good faith and aren't impressed then you might want to contact your local Corteva representative and speak with them. They are usually pleased to talk to customers and engage with them when issues arise.

Buttercups are difficult to eliminate in my experience, I've used MCPA at full rate and with adjuvants etc etc and never had what I would call total control from it.

Advice needed please.

have had a few cattle affected by celery leaved buttercup. For those that don’t know it has the highest concentration of runculin of all the BC varieties. Cattle can get a taste for it and hunt it out….. causes vasculitis and possibly death.

Took quite a bit of hunting to find the plant around the farm but now we have we need to kill it. It will involve spraying in the bottom of hedges… primarily blackthorn and some hawthorn. What spray would members recommend for a sure kill? Would rather not glypho nor kill the hedges. Application method shouldn’t be a deciding factor (I.e. knapsack)

thanks All

Forefront t will go a long way out of 1 or maybe 2 nozzles at the butt of a hedge
Not much weed wise will survive
Hedges will be ok as long as the boom is low

Hawthorn is pretty delicate!

Delicate! Not the bloody one that I fell into some years ago!

In this scenario I would probably try MCPA (find out if it will work out the species in question) as it is a lot safer and gives a wider margin for error. Using something else near hedges and possibly gardens etc etc would give me the willies frankly.

@ollie989898 can I mix MCPA with fulroxypyr? Or will they fight each other? One field has buttercups and docks. Don't want to rely on the MCPA for the docks.

We did a small grass field almost a month ago with full rate Forefront. Some of the buttercups are looking poorly and others look like they were happy for us giving them a drink.

Spot spraying seems to do them probably get a bit more on them

I always made suggestions based on a visial check, but would obtain an agronomist report for the tricky ones
