60% Metsulfuron Methyl
Controls Bahiagrass and Grassy,Broadleaf Weeds

2 oz. bottle containing 60% Metsulfuron Methyl (Same Active Ingredient as Clean Pasture, Manor)

Farmers in our area use Cimarron Plus, Ally, Manor and Clean Pasture for their pastures all of which contain this chemical.  Some homeowners were trying to use the same products for their lawns by guessing how to dilute it even though they were not labeled for lawn use.

Good news! MSM Turf Herbicide is now labeled for lawn use with exact instructions.  It is a high quality university tested formulation specifically targeted to broadleaf and grassy weed control on ornamental turf, such as lawns, parks, cemeteries, golf courses (fairways, aprons, tees and roughs) and sod farms. It is the best bahia grass killer.

MSM is absorbed through the surface and roots and stops the weed growth.

For Lawns:

Use 1/10th of a teaspoon per gallon of water for homeowner lawns.  There is a handy measuring cup specifically for this type of product to break it down as small as you need for your purposes.

Effective for the Control of:

  • Bahiagrass in St. Augustine & Bermuda
  • Annual and perennial broadleaf weeds
  • Clover
  • Dollarweed
  • Foxtail

Looking for total nutgrass control? This product kills the top part of the plant but not the tubers. I think Sedgehammer would work better to kill your nutgrass. Click here for more details.

Important Tip:

Bahiagrass is a very hard-to-kill grass and when using MSM Turf Herbicide, you will need to add a surfactant (a product that makes it stick longer) with it. We recommend Hi-Yield Spreader Sticker (a non-ionic surfactant). You’ll need 2-4 tablespoons per gallon of water.

  1. I have purchased this product to kill the carpet burrs on my property. However, I have three acres and use a tank sprayer. Could you instruct me how to mix this product per gallon with a tank sprayer or hose end sprayer? Ideally ounces per gallon. Thank you.

    • Hello, Kinton. Carpet burrs,a.k.a. spurweed, sticker burrs, are very difficult to get rid of. The key is to start before they set their seeds which is this time of year. However, saying that, here is the breakdown on tank spraying: a 25 gallon sprayer use 4/10th of an ounce in 25 gallons of water for 1 acre.
      Another product, which with a stronger percentage of active ingredient is restricted, is Atrazine. You would apply that in December and would probably take 2 years to eradicate your lawn from the spruweeds.

  2. can this be sprayed in flower beds

  3. Hi there, Do you know if it can be used on Wedelia or creeping oxeye ? Ive tried everything to get rid of invasive plant with no sustained success!

  4. I sprayed this on much hated Bahia in my yard. It was tall when I sprayed so I cld really see where to spray. How long does it take to kill Bahia?? Or shld I have mowed first?? Thanks in advance

  5. I noticed that the active ingredient in this product is the same as many others that are labeled to control johnson grass. Is there a recommended mixture for this product to remove some johnson grass from my lawn. it is small but everywhere and i keep it mowed weeky so it doesnt spread from seeds but rhizomes are still intact, glyophosphate isnt an option since it is so spread out and short.

  6. Mike Romano says

    Using the prescribe mixing rate ,is this product safe to use around trees ?

    • Can thi product be used around trees and will it kill Johnson grass?

      • This product does not kill johnson grass. I believe if you are using this in your yard, the dosage will be very small, you will not be spraying this on the leaves of the trees at a higher dosage rate necessary to kill the trees.
