Some years ago I used neat (undiluted) commercial glyphosate and a small paintbrush to kill a load of knotweed and deadly nightshade. Paint the leaves and the whole thing dies - systemic weedkiller.simon wrote: ↑Fri Jun 18, 2021 12:58 pm Aye it was another treatment of glyphosate that lead to this. Just spraying the leaves only knocks it back, it needs severing so the glyphosate can directly penetrate it. And that's where my problems begin... .
Especially as it has grown into the iberis next to it so it needs careful spot treatment.
Hopefully it's all treated now. If not the next step might but a bulldozer!
I used one of those small paint tester pots with an inbuilt small brush attached to the lid. Very good for spot killing dock/bindweed etc.
