Plant ID - Is it horsetail?

[Pea79]

I do have some horsetail sprouting up in this area of my garden, which I am about to treat with Kurtail Evo weed killer. However, this plant feels softer and looks slightly different, so I'm not sure if it's horsetail or not. It looks like it has tiny yellow flowers on the ends. I don't want to kill this plant if it's not warranted. Thank you!

Thanks, everyone!

Based on the online pictures, it looks mostly like cosmos. But until the little buds bloom into something, I can't be sure. The horsetail/marestail weeds are growing around it, which is what made me suspicious.

I've not used Kurtail Evo before but decided to just go straight for the plunge because my parents have failed for 30 years to get rid of the horsetail/marestail weeds from their garden. I appreciate that the greenery around it may also die, but I'm prepared to risk it to get it under control before it spreads any further. It's already growing up through the patio.

Whorled tickseed?

That is really good to know as it is the approach I am taking with nearly all of my garden. The bit where I feel I may have to resort to chemicals is about 8ft square ish and totally covered. It is more that I can pull out.

It could be coreopsis verticillata which is a lovely plant.

I’ve changed my mind. I now think it’s a coreopsis

It could be chamomile.

Thanks, everyone.

Coreopsis verticillata seems like a good shout. Here's a close-up photo of one of the buds on my plant and it does look similar to those of a coreopsis.

Try bruising the plant before using Kurtail, I seem to remember horsetail has a waxy cuticle which resists weedkillers. If it doesn’t work first time (give it 3 weeks), and you want a second application, paradoxically a weaker solution works better as the uptake is better

Ignore the second part, Kurtail has a second active ingredient and claims to be lipophilic, so that’s the waxy coating dealt with. Note it’s a professional weedkiller and you have to comply with professional standards
