I need to get rid of button weed and dollar weed in my yard in Louisiana. My turf is mostly St Augustine. My yard is 100' X 125' . Can I mix this in a 2 gallon sprayer to broadcast over whole yard, and how much should I use per gallon.
Mike on Sep 27, 2016
BEST ANSWER: You will use about 0.2 teaspoons per 2 gallon sprayer to cover 2,000 square feet
After I've sprayed with recommended application how long do I need too wait to mow again,?
A shopper on Aug 12, 2017
BEST ANSWER: I would wait at least a couple or 3 days or even a week. The manufacturer recommends less time. It works great. Mix 1 teaspoon of MSM and 4 tablespoons of Dawn diswashing detergent(will help if it rains soon after spraying) per 4 gal sprayer. I add the MSM and Dawn when sprayer is half full with water and shake back and forth about 75 times. A good mix is important. It takes 3 to 4 weeks for the bahia to die. You will have to keep spraying afterwards from time to time but it gets to be less and less. Seeds can sprout for quite some time. Plus, you will miss some of the bahia. It works great if you follow the above.

Apply how long before expected rain?
A shopper on Aug 13, 2017
BEST ANSWER: You do not want to apply MSM Turf before a rain. MSM will translocate if it is not rainfast and you can damage desireable vegetation like trees and bushes if you get runoff. We recommend to spray during the heat of the day when you know MSM will dry quickly and stay exactly where you spray it.

We are spot spraying for specific weeds and not broadcast spraying. Thus the use rates per acre are not useful. How many ounces of the MSM Turf powder per gallon of water should we mix? We will be using a small trigger spray bottle.

Is it too early right now to apply this to St. Augustine in south Louisiana? Grass is still dormant brown but weeds are already coming in. There are a few blades of green grass starting to appear. This is our first week this year where temps have stayed in the 60-80 range.
A shopper on Feb 16, 2018

Can we spray our St Augustine with MSN60 now that temps are in the 90s?
Smart on May 9, 2018
BEST ANSWER: You can spray but not during the sunny part of a day.....you will cook your grass. If you have animals, you should spray when you can either walk them away from the chemical coated grass for 4 hours. The chemical works best if it is sprayed either very early morning or later evening in dryer weather so that it has time to set and dry in leaves of the dollar or other broad leaf weeds. Never spray or water during the sunny hours as you will burn both grass and weeds. Keep animals off the grass for at least 4 hours And until the chemical is completely dry. Do not water the grass for a day after spraying the chemical

Can I use msn now to kill dollar weed? What other weed will it kill here in South Louisiana? I have st. Augustine in the back and centipede in the front.

I just purchased MSM turf for use on my centipede lawn. I will spray an acre of lawn. I see the amount to use is .25 but in what amount of water do I mix this? Is it per gallon or?
A shopper on May 7, 2018
BEST ANSWER: Centipedegrass: Apply 0.25 to 0.5 oz of this product per acre for
weed control. Some chlorosis or stunting of the turfgrass may occur
following the application. You will want to use 50 to 100 gallons of water to cover the area.
IMPORTANT: Addition of a nonionic surfactant of at least 80%
active ingredient at 0.25 percent by volume (1 qt/100 gal) provides
maximum performance, but may temporarily increase chlorosis of
the turf.
Allow one week between the application of MSM Turf Herbicide and
other pesticide products. (This guideline can be relaxed where a
severe insect or disease attack requires immediate treatment.)
