If memory serves me, and it's not been cooperating lately. I heard talk of a new to us invasive weed that throws yellow flowers in Minnesota last year. I snooped the net and didn't find anything that rings a bell so I am not much help in that department. Try the county Extension office. They should be able to help on ID and control.

You might look at Rag Wart, or Hawks Beard. I googled in yellow daisy like weeds.

L-V6 will take care of it

I would guess its a form of goldenrod.

Tansy Ragwort
Tansy ragwort produces pyrrolizidine alkaloids - these can be lethal if ingested by cattle, horses and deer. A member of the Asteraceae taxonomic family, this large biennial or short-lived perennial herb is native to and widespread throughout Europe and Asia and has spread through Flathead, Lincoln and Sanders counties. Stems can grow to a height of 5.5 feet (1.75 meters), with the lower half simple and the upper half many-branched at the inflorescence.

The plants in the picture you attached are affected by 2,4,D or other herbicide. They are Tansy. Jim

And to make it worse, I know some folks (not me) who are on some kind of a diet challenge thing. One of the items recommended to replace some of the protein in a normal diet is something called "keen-wa" or something like that. Out of curiousity I tasted some. NO flavor at all, and a less than desirable texture and consistency. I googled it. It is NOT grain. It is seeds. Seeds from the Amaranth weed, more commonly known around here as PIGWEED! Farmers and gardeners do their best to eradicate it, only to learn that others GROW the stuff.

Tansy Ragwort was my first thought, too, Janicholson, but I don't believe it is. We've been dealing with it in western Washington for most of my life (my dad offered my sister and I 10 cents a plant to pull it up on our 250 acres in 1957, and we gave up after a day because we made less than a dollar between us- wish that offer was still in effect!). The flowers look right, but tansy stalks are much more upright and straight. Flowers are at the top, not all through the plant like the one Glennster showed. It may well be a variety of tansy, just not ragwort, and may or may not be toxic.

As far as control, 2,4-D will kill it back, but it will often grow back the next year. Ditto for pulling. Milestone seems to be working better, but still not easily controlled. Not sure about Roundup, because ours is always in pastures, so we can't use it.

Janicholson · May 30, 2017

I think the weed is Tansy but affected by herbicide already applied. curly stalks and weird growth are the result of the partially effective treatment. Jim

Here in my part of California, we are being over run with wild daisies, which looks similar to your weed. Some fields are so thick it is hard to walk through. The plants get 5 ft high. They do mow real good though, but impossible to see where you are going, unless you know the field. If I were you I would sure try to get rid of the plants. I often think what our area looked like years ago without all the foreign plants. Stan

We have a similar weed here in MI- one of my hay fields you would have thought I planted it on purpose it was so universal. Fortunately, the yellow-flowered weed grows even faster and earlier than the grass in the hay mix, and the local COOP has a weed wick for rent. Set the wick cart up above the hay early in the Spring, just wipe the Roundup right on the weed. Worked great, I pulled a total of three weeds from the edge of the ditch in that field this year.

Our Extension agent said Yellow rocket. At first, Dad was pulling the weeds and found the tuber-like root, he said it was a kind of parsnip. We cooked and ate some, not bad, but what isn't tasty when fried in real butter?

Amaranth seeds and plants are high in food value,Inca and Aztec Indians in Central America had a whole civilization based around it.The seeds are far higher in food value than
any of the common grains grown in the US.Pigweed is the wild variety,my goats and cows love the stuff.Chickens will do real well eating the seeds out of the head.
