Identify the weed

[Banj0Bolt]

I'd love to identify these as I want to spray them. I live in Ireland and the land would not be the best. They disappear in winter, and in summer they grow as high as the silage, no flowers on them.

looks a bit like rose bay willow herb but they have a mass of pink flowers and spread like wildfire which is another name for them. they would certainly grow as high as the silage but would expect to see flowers at that stage so just a guess.

I have a plague of these, does anyone know what it is or what herbicides will kill it?

Is it definitely not RBH? Whatever it is 2,4D plus MCPA would likely curl it up well. Try a test area?

It looks like a member of the polygonum family because it has ochrea. It looks like it spreads underground but it’s not clear if it is a wetland situation but I think it is wet/damp. It could be one of the bistorts or persicaria hydropiper?

2,4D? RBH? I'm sorry I don't know what those are
The area in question is wet for a few months of the year. The field was sprayed with Mortone a few years back for rushes, it put this unknown weed back but didn't seem to kill it.

I'm starting to think it's called redshank / jesusplant

I downloaded an app called "Scouting" (from Xarvio (?)) a few days ago and it will identify a weed or disease (and other stuff I have yet to try it on like N status) from a photo you take on your phone of whatever you need identifying. Alas, I took a screen photo of this thread and it couldn't do it.

You are in the right weed family. But does it spread underground? If you dig it up does it have long roots that give rise to new plants? Or is each plant an individual?

yes to me it looks like common or garden (on heavy dampy ground ) redshank .easy to kill if it is even a top or 2 will as its an annual.

I don't think it is the common Redshank (Polygonum persicaria) but more likely Polygonum amphibia.
Very similar plant and control would be the same too.

24d is a chemical

Rbh -rose bay herb

What kind of herbicide might kill it? Without killing the grass

24D plus MCPA
As you don’t know what 24D is I assume you don’t use a sprayer, so ask the guy you will get to do it what they suggest.
