MSM Turf

I use .05oz. per gallon of water. Most of the time you have to spray Virginia button weed twice. It's a continuous fight.

I think i do 1oz per gallon

I hope not as a max application rate is usually 1 oz per acre, but if you have a sprayer that can cover an acre with 1 gallon I want one!

Is it possible to mix MSM and Celsius?

I suspect you can but I don’t know for sure. If you’re having to spray 16,000 sq ft I can understand why you’d want to mix. But if you really want to do this shoot an email to Dr, Ron Strahan, weed control specialist with the LSU AgCenter rstrahan@agcenter.lsu.edu - he’ll know.

Are there weeds you need control MSM Turf is not taking care of? I use Celsius to control doveweed, green kyillinga and carpetgrass which MSM Turf doesn’t control, otherwise I use MSM Turf. Celsius will control just about everything MSM Turf will, except Bahiagrass, but it’s much more expensive.

1 oz per gallon is for MSMA

Had to figure out how to post pics. I'm getting dominated by VBW, dichondra and bermuda. I've been cutting at 3.5" to try and choke out the bermuda.

Isn't this doveweed?

Looks good from
far!!

Your weed iDs are correct though the second to last almost looks like doveweed to me (hence my earlier comment that when young VBW and doveweed look very similar) but you might be right. Here is info on both from the AgCenter including ID.

Doveweed

I use this small scale for weighing herbicide “GDEALER DS1 Digital Pocket Kitchen Multifunction Food Scale for Bake Jewelry Weight, 0.001oz/0.01g 500g, Tare, Stainless Steel, 12710619mm, Silver” , $13 on Amazon.

Yes, cut your lawn high, St Aug I presume?, to choke out Bermudagrass as there is no herbicide to control Bermuda in St Aug.

The last thing to emphasize is make sure your applying the correct amount of herbicide, by weight, per 1000 sq ft of lawn. For example, for VBW I use the 0.75 oz per acre rate, which equals 0.5 gram of MSM Turf per 1000 sq ft. It doesn’t matter if you use 1 or 2 gallons of herbicide solution to get full coverage over the 1000 sq ft the key is to insure you apply 0.5 gram of MSM Turf over that 1000 sq ft. So feel free to mix 0.5 gram of MSM Turf in either 1 or 2 gallons of water just make sure you apply the entire 1 or 2 gallons over 1000 sq ft of lawn area.

And addition the non-ionic surfactant is critical to waxy leaf plants like VBW, doveweed, dichronda.

Weed control in lawns is a war you need to win, not just a single battle, so persistence and patience is the key. If you’re not doing so now, consider using pre-emergent herbicides in fall and early spring, they can be game changers, not for VBW but many other common lawn weeds.

Yes. I typically spray 1 gal/1000sf but up to 2gal/1000sf is very common.

Do a test plot on concrete to figure out how much you’re spraying per say 100sf, to make things easy.

So if I'm spraying 8,000 sq. ft I would need 4 grams of MSM. If I mix 4 grams with 4 gallons of water or 4 grams with 8 gallons of water it will do the same thing as long as it is all sprayed within that 8,000 sq ft?

That is 100% correct - use any amount of water you feel necessary to get full spray coverage, all sprayers are a little different. For MSM Turf and Celsius herbicides think of the water more as a carrier for the herbicide to get the right amount (weight) of herbicide over the coverage area rather than a dilutant to decrease its strength prior to the application.

I think MSM is like 1/10 of MSMA the little bottles cost about 10 times as much though. I guess it evens out.
