Stickers in my yard. What kills them?

[SabreKiller]

I HATE these darn things. I've been digging them up whenever I see them, but sometimes I hit them with the mower and then it's too late. I've got some MSMA, will that do it? I've got Round Up as well, but don't want to kill anything else. My yard is buffalo grass.

Thanks

Pulling the up is what worked for me. They like hot an dry. It takes a couple of years, but I don't have anymore after being very diligent on pulling them up

Several rounds of weed and feed worked for me

did the weed and feed have 2 4 D in it ?

I have 3 ac and they are all over the place hate then! Try draging an old blanket around the yard to pick them up and weed and feed.

Here's the deal.
I have the same problem with grassburr's too. Too many to pull, so I have done the following:
1) Once the soil temp reached 75 degrees, usually by March 15 in my area, I spray the entire yard with a pre-emergent herbicide and continue to do this every 6 weeks until the yard goes dormant.
2) Heavily fertilize the yard every 90 days with Scott's Bonus S. I use this because it has the minor minerals which a healthy yard requires (iron, molybendium, calcium, etc..). Regular 13-13-13 or other fertilizer usually does not have these minerals.
3) When I notice grassburrs growing, but before they put off a seed head, I will spray the entire yard HEAVILY with 'Image'. The active ingredient here is Imaziquine (sp). Any product designed to kill crab grass should yeild sufficient results. I do not know how this product effects buffalo grass because I have a bermuda grass yard. Be sure to read the label. Image takes a while to work and it must be watered in after application.
4) Sufficient water.

If you have some MSMA this should do the trick better than Image or equivalent. The EPA in thier superior wisdom has banned the use of MSMA because it has detrimental effects on some d*** bug or something foolish like that.

2-4-d application every 90 days doesn't hurt anything either.

I have followed this regimen for the last 2 years any my grassburrs are all but gone.
At the minimum fertilize and water every 90 days.

Hope this helps.

Once you get them down to manageable levels, try using a cotton swab or sponge paint brush and applying Roundup to each plant--I paint it on the stem below the seed head, and then pull the seed head off. Also use AMAZE-a pre-emergent herbicide every 6 weeks during the growing season. It's a long hard battle, but it is winnable. I've not tried IMAGE, but that's next on my list to try.

Best thing is to pull them and don't drop any stickers back in the grass to sprout another plant. I had lots of them several years ago. I pulled them everytime I saw them. Every year there were fewer. After about 5 years I never saw another one.

Fertilize

Dig the out. Then in the fall and spring put corn gluten out.
