Any clue?

I thought so. I was hoping it was some kind of pea/bean I'd never seen before. I T&M a pea/bean/buckwheat mixture in this field and very little came up. Probably had something to do with lack of rain earlier in the summer. Went through quite a spell with none. Most I've ever seen of this kind of plant too. There are a bunch out there. going to hit it with roundup in a few weeks.

You need to kill it before it seeds. Hard to get rid of.

Surmount is the best I have used for it. Grazon next will work if you don’t have an applicator license, but mix it heavy and use a good surfactant.

Thanks. Roundup or 24d won't work?

I've been using the plantsnap app lately when I want to ID something. Just take picture of the plant and it gives a suggestion on id.

I've read that you should mow this stuff before it seeds and keep mowing it until late fall when you spray it. I don't have access to a sprayer right now, so I guess mowing it is better than letting it seed out?
