What is the best weedkiller for dealing with ivy?

Glysophate (roundup) will work if you damage the leaves a bit first,
mixing a bit of wall paper paste with it helps it stick to the waxy
leave too. But you only really need to use weedkiller if its got into
stone work as its quite easy to dig out the roots in soil

I use one called Resolva. Spray and wait a while.

There isn't one available to the public, and I doubt there's one for
professional use.

I've wasted time and money trying to control ivy with glyphosate. It
might brown a few of the new leaves before they get a waxy covering, bu
that's about all. Even Monsanto admit it's ineffective
(https://www.monsanto-ag.co.uk/roundup/roundup-amenity/difficult-weeds/ivy/):
"Due to the exceptionally thick waxy cuticle, fairly small leaf area and
creeping nature, this weed is usually classed as resistant to glyphosate."

They claim that Roundup Biactive or Roundup Probio offers the best
chance, but these are just formulations with varying surface-active
agents to try to give better penetration.

Several years ago I tried making different formulations of glyphosate
(all maximum recommended strength) and spraying adjacent areas of ivy. A
solution in about 30% isopropyl alcohol, and another in a white spirit
emulsion, were no better than glyphosate alone - and that was entirely
ineffective.

If it's growing up walls or trees, cut through the stems just above
ground level. It is better to try to pull of the stems as soon as you've
done the cutting; once dead and dry they are rather brittle and will
tend to break up rather than pull away.

If it's ground-cover ivy, some people have tried bringing in goats to
eat it. It /might/ work if there's nothing else they find more palatable
in your garden (which is very unlikely). Other than that, it's a
heavy-duty strimmer/brushwood cutter to bring it down to ground level.
You can then try spraying what's left with glyphosate and hope it gets
absorbed through the cut stems. If it's just a small area, covering that
with black polythene will stop the ivy growing, but it will also stop
anything else wanted growing.

If you dig down just below soil level and cut it off it will die. Ivy
has no dormant buds below ground.

Neat trick. I'll remember that

Physical removal is much more efficient.
Cutting through the stems near the roots will see it off.

Ivy (and holly) seedlings will survive a direct hit with glyphosate. The
waxy coating on their leaves is surprisingly effective.

BTW at this time of year it is a waste of weedkiller as well.

Plants have to be in rapid growth for maximum effect,

Thank you for all replies.
