What will kill this weed?

[LauraleesFarm]

What will kill this weed? I have patches of this vetchy weed in the higher drier areas of my hay meadow. Have sprayed a stronger than usual mixed round of Grazon Next and some patches died, some just stunned back and regrew, and others unaffected. It chokes out the bermuda and seems to thrive on drought.

I have on hand: MSM, Remedy, and Duracor (I think that's the name). I'm hoping one of those will kill it. What do you all recommend?

It looks like a grass, and not a weed. Maybe crabgrass.

I agree, none of the products you listed kills geass.

Try and find a young seedling and look to see how many seed leaves. Grasses just have one. The ones that have 2 seed leaves (dicotyledons) are the ones affected by the broad leaf herbicides like Grazon.

It is not at all like the crabgrass growing in my backyard. I'll try to get better pictures.

A better picture might help, I think I have something like it but have no name for it.

 

[kenny thomas]

Download plantnet.net and it will identify when you take a picture.
Much easier to use the correct product if you correctly identify it.

Google broadleaf signalgrass and compare pictures.

It is not signalgrass.

I have quite a bit of it as well, 24D and Grazon has not taken it out

Looks more like a weed that resembles a grass. Is it doveweed?

Try eraser

Just be aware that Eraser is a generic Roundup. It is non-selective - will kill most everything, desirable or not. Generally not used on a pasture or hay field unless you are starting over.

Went and blew the picture up. It may be carpet grass. It will choke out bermuda. Grazon and 2,4-D are not going to control this grassy weed. Hurleyjd's suggestion of glyphosate is your best bet. We used a pint/acre of RoundUp on crabgrass in a bermuda hayfield with great success. We sprayed 3 days after cutting and baling the bermuda before much regrowth. That rate may ding and yellow the bermuda, but it is 1/10th the rate to kill bermuda.

Yep. Eraser has been around a long time and is just one of many different brands of Glyphosates after Monsanto's Roundup ownership patent expired in 2003. Eraser is a wide spectrum, NON-selective herbicide labeled at 41% glyphosate.

Works on sandburs in Bermuda too.

Here are better pictures. It has a taproot. The stems are almost woody, but thin. It gets about 6-8" tall.

It does not match the pictures of carpetgrass that I found online. See new pictures uploaded.

Not sure what it is but I'd be inclined to try fluazifop on it.

 

[M.Magis]

Definitely a weed and not a grass. Maybe prostrate knotweed?
