Soil Test and Weed ID

I’m not seeing the pictures

Grassy Weeds in the middle two pictures are dallisgrass.

Any idea where I can get ammonium sulfate? Will this work?

Craw was right on with what he said. I do see some VBW in the pictures too. MSM or Celsius for that as well, I prefer Celsius. In the top picture did you just water or did it just rain? That is a lot of water on the ground and could cause issues if that is because of poor drainage.

In this second picture I can see where you are bringing in sod but the dallisgrass is located in the bermuda. There are some options. You can buy tribute total but it is expensive. You can buy glyphosate and water it down by about 25%. Spot treat the dallisgrass every two weeks. You can also spot treat with Celsius and sedgehammer. Spray the leaves like normal but spray the center mass until wet. Do this again two weeks later. I followed up with someone today and the dallisgrass is actually turning yellow and purple. I spot treated it again today and will follow up next week.

I have Dallisgrass in my back yard so thick that I have to cut every couple of days. Other than digging it up, is there anything I can spray to get rid of it?

Grass type?

Are you absolutely sure it is Dallisgrass - some posters have recently posted photos of what they thought was Dallisgrass and it was Crabgrass, which is much easier to control, and others have posted photos of what they thought was “crabgrass” but it was Dallisgrass.

OK, top and bottom pics are Dallisgrass but middle picture looks like crabgrass to me. Let ronk weigh in on this - he’s better at weed ID than me. You also have some common Bermudagrass mixed in.

With crabgrass, an annual weed, in your centipede lawn you can kill it with sethoxydim, but the best control of crabgrass going forward would be to apply pre-emergent in late winter - early to mid Feb in south LA. Pre-emergent is very effective on crabgrass. Sethoxydim will also kill the Bermudagrass.

Another poster on this board has said they have good success controlling Dallisgrass with sethoxydim, but I don’t know as I’ve not seen that recommended in university extension literature. I’m going to link this paper on Dallisgrass control to read to see what might work best for you. LINK.

I know the best herbicide Tribute is crazy expensive, but there are cheaper alternatives. I don’t want to speak for ronk, but I think he is recommending mixing Celsius and Sedgehammer herbicides, two of the three ingredients in Tribute as a less expensive alternative. Dallasgrass is a perennial weed so it going to be difficult so plan for a long war, not a brief battle, to rid yourself of it if as you say you have a yard full. Now if you don’t have so much Dallisgrass, try digging it out or spot spray or wipe it with glyphosate (generic “Roundup”)

You are right. Dallis, crab, dallis.

I am testing Celsius and Sedgehammer (I'm not a scientist or anything). Normal spray on the leaves and then spraying the center of the plant until wet. It is showing some promise. The dallisgrass is brown and yellow. I'll do a repeat application next week. I'll post pictures.

Mix celsius and sedgehammer but just a warning it's a strong mix. Any centipede near the center of the dallisgrass will yellow because you are spraying to wet. It is going to take more than one application for sure.
