I have a couple of yards with just a few patches of dallisgrass so I'm thinking of doing a paintbrush glyphosate method or something similar. Would probably be a lot easier than trying to use a selective herbicide on it at this point.

 

I hear ya. Once they took the residential use off the of MSMA/DSMA label, it has been tough to control DG. Not sure if this is an option for you since you’re working with warm season turf and I am cool season turf, but I have used Ornamec 170 on it. It is labeled for it, but timing is very explicit…GDD needs to be approximately 260-320. It states that on the label, so I could be off on that; always have to look at it as I only use it on a couple of lawns for that purpose. Mainly I use it for spot spraying it for Bermuda eradication up here, so again that may not be an option for you.

 

Celsius /certainty with a surfactant is about your only option on centipede. Tribute is not safe on it. It will take multiple apps and probably better results late summer/early fall when dallis is storing carbs and growing slower.

 

On Centipede, your options include repeated applications of Pylex. That will actually do more to Dallisgrass than Celsius. There is no such thing as a one time kill on Dallisgrass no matter what the product. Objective should be to use the most selective application possible.

 

Interesting. Did not know that. I just assumed that pylex was harmful to all warm season turf

Few patches. Bring shovel. Dig it up. Done.

 

You can also put a few tablespoons of granular fert lumped up dead center of each of the patch of dallis. Use the highest N you can. Granulated urea works well. Then leave it as is. It'll be dead in a week with very limited burn to the surrounding turf. Works best when the lawn is not actively being irrigated.

 

I've never heard this, gotta try thanks

 

Also can use Sethoxydim on Centipede. Just throwing that in

 

I use this + Celsius. 3 shots. It will remove most, if not all grassy and broadleaf weeds.

 

I had success stunting it, I rarely had any success killing it outright without going strictly on a schedule. 7-10 days, hit it again. If you wait longer, damn DG comes right on back.

I'm to the point with Dallis that it gets Gly no matter what. Don't care how big or small, gly. Nuke the sh** hard, deal with the cratered landscape by pushing with fert.

At what rates are you using this mix?

 

2.5oz/a Celsius
16oz/a Sethoxydim
16oz/a COC
22gal/a carrier

3 shots 21 days apart, before temps hit 85+.

 

Always worked for me. Might take three apps spaced 2 weeks apart. I've experimented with adding imazaquin to the Celsius and certainty...works. Turns the dallisgrass black
