temperature restrictions on St Augustine??
A shopper on Feb 16, 2018
BEST ANSWER: Excessive injury may result when MSM 25OD is
applied to turf that is under stress from drought,
insects, disease, cold temperatures (winter
injury) or poor fertility.

You will want to wait till the lawn is no longer dormant to control spring and summer weeds.

Apply a good pre-emergent, will control most all weeds this season. https://www.solutionsstores.com/prodiamine-65-wdg-barricade-herbicide

robert b on Sep 16, 2017
BEST ANSWER: Yes, MSM is fine for use on St. Augustine and it does not list any differences in strains, but you can do a test spot.
I have Va Buttonweed in my St Augustine grass. I live in Louisiana.
I have a Orthro Dial n Spray. I need to cover 15,000 sq ft. I would like to know the amount to add to the 32 oz canister and a what rate to set the dial for the MSM 25 OD.
JohnMar on Sep 15, 2016
BEST ANSWER: You want it to put out 1.12 to 2.23 FL. OZ. PER ACRE, so for 1/3 of an acre use 1/3 of the rate, this would be about 4 teaspoons to cover your size.

Economical & Easy to Use
This product was economical and easier to use than MSM 60DF. It came in an easy to measure bottle. It took care of my broadleaf weeds quickly in my front yard.
