Mixing Weed Control Chemicals
Posted on 7/21/23 at 11:03 am

I have a bunch of post emergent weed control chemicals and I’m curious if I shouldn’t mix any of these chemicals in the same batch. Part of the reason I have redundant chemicals is because my yard is a mix of centipede, dallisgrass, Bermuda, and St. Aug. I listed these in order of prevalence.
Please let me know if there’s a concern with mixing any of the following:

Weed Free Zone
2,4-D
Grass Beater II
Atrazine
Celcius
Sledgehammer
MSMA(purchased before relabeled)

Worst case scenario is you have a few brown spots for a month or two. I combine 2 at a time with no issues. I have bermuda grass.

Thanks for the response. I am also concerned that mixing of the chemicals could negatively impact the effectiveness of the chemicals should they react with each other when mixing.

The Celsius/Sedgehammer mix would take care of almost everything and could go on all grass types.

When using one or both of these chemicals, would you add a surfactant?

We used to mix 24D and roundup on fence lines and it works but it takes a little longer to show.

If I apply it weekly or biweekly would it be too much? If so, how often should I apply it?

You should throw in some mesotrione for good measure.

That mix will kill almost anything on the first go round. Only thing that may require a two week follow up is VWB, lespedeza and spurge. You can suppress Dallisgrass by spraying it monthly. You can spray it weekly as long it is a new weed in a previously unsprayed area.

I have been spraying my yard every two to three weeks and unfortunately it is still full of weeds. I’m concerned that I might be spraying too much and hurting the lawn.
Another question I have is can you aerate your yard two much? Everything I have read on the internet says annually maybe twice a year. I aerated in May and the soil seems compacted again.

My problem with aeration is I dig up dormant weeds and it's like I've never sprayed before. Every. Damn. Time.

Could be new weeds. A lot of times people think it is the same weed but really there are a lot of the same type of weed seed in an area. If you are sure it's the same weeds then it could be a too strong/too weak mix, no growth from the plant, no surfactant, etc.
Yes and no. Can you damage your lawn by aerating every week. Yes, but show me the maniac that is going to do that. Two aerations a year is fine.

I sprayed Celsius and MSMA bout a week ago, together.

That’s my go to combination. Add a little surfactant and some dye so I can see where I’m spraying. Works great. I’ve used Celsius and Certainty with good results too.
