Control Solutions Quali-pro Msm Turf Herbicide 2 Oz

UPDATE: It didn't actually "kill" the POA, but then again it's not actually indicated for it. It died off above ground, but all seemed to recover and came back with a vengeance. I've blanket sprayed 2x, I think that's the annual limit because it supposedly stays active in the soil. Active? Oddly, there's dollar weed coming back? I still call this a 5* product for doing what it says, but am now shopping something a little less harsh, that can be used more often for continued control. This did a good job killing clover, dollarweed, vbw, and poa in my st aug. Crabgrass is oddly iffy. Will decimate one plant, seemingly no effect on another right beside it. Be patient. It took about 4 weeks to see any yellowing, 6 for complete dieoff. I waited 4-6 weeks to respray. It's hard to mix, used a gram scale. What I'm using works out to .05oz for 2 gals/1/2 ac, in the included measuring cup. I hear this is hard on oaks, so stay out of the drip line. It may be hard on dogwoods, I had a sick one that is suddenly spiraling to its death. Be ready to battle sedges, this stuff almost seems to feed them, or maybe it gets them going by clearing competition. I bought a house in the winter, so didn't know I bought from a weed farmer. Excited to see what all this work brings next spring. There are a couple cheaper options on amazon. Shop around. They all seem to say spray or liquid. I don't think they are. I think it's all granular and you mix it into a spray. As I understand it, once mixed it doesn't have much of a pot life.

This product works fine in Myer Zoysia turf lawns, and is very effective against Virginia Buttonweed (assuming the directions are followed and the second application is made). The active ingredient of this product (metsulfuron methyl) is the same as the herbicide formerly sold under the trade name “Manor”. Metsulfuron is one of only two selective herbicide chemical groups actually shown to be effective against Virginia Buttonweed, and MSM is the only one of these chemicals I have found that is sold in volumes economical for residential use. In fact at my local farmer’s co-op, even the container of MSM I found was 3 times the cost of what I paid on Amazon and would have been enough chemical to treat my yard for over a decade (probably far past the shelf life of the chemical in an opened container). MSM is very effective against several other broadleaf category weeds, but this chemical is not for control of grass turf weeds (e.g. crabgrass, goosegrass, dallisgrass). Also, it may not be completely clear from the description, but this product is in dry form, so “oz.” refers to the unit of weight, not fluid ounces. I was initially concerned when I read the chemical data sheet prior to purchase that this product would be impossible to mix up in lawn sprayer sizes (before I realized that it was not referring to a fluid ounce), but the product is not too terribly difficult to mix for a residential scale application (although the chemical data sheet directions are written for large scale applications). The applicator cap included has volume markings down to 0.1 oz. The recommended rate for Buttonweed (in Zoysia) is 1 oz per acre, so with a 2 gallon hand sprayer, the minimum marking of 0.1 oz will cover about 0.1 acre mixed at the 20 GPA rate. Use of a non-ionic surfactant is highly recommended, as this chemical needs to contact vegetation to be effective. Update: After two seasons, MSM has had quite an impact on the Virginia Buttonweed presence in my lawn. The turf farm where I purchased my Zoyisa had quite a buttonweed problem, and for the first two years after laying turf, it was pretty heavy in several sections of the lawn. It took two uniform applications the first year to start making a real difference. By the second year, I really didn't have to apply to the whole yard again, as a couple of spot sprays spread over the season seemed to do the trick. I haven't noticed an harm to the Zoysia grass after use of MSM.

I have a small Bermuda lawn that was covered in several winter broad-leaf weeds. Lawn was probably 70% weeds. I previously tried several big box store products for post-emergent, and they never worked. This stuff finally worked! I applied at the end of January. In my region (Southeast US), Bermuda did not go fully dormant this year. After 4 weeks, the Bermuda is greening up well and starting to fill in the areas previously covered with weeds. Now about 10% of lawn is covered with weeds (mostly Poa Annua, which this product is not labelled to control). Pros: - Great value, it will last me several years and is very inexpensive compared to other products - Great broad-leaf winter weed control. Got rid of hairy bitter-crest, hen bit, plantain, and chickweed (and I'm sure several other types) successfully. - Does not seem to hurt Bermuda at recommended application rates Cons: - Slow acting. At 2-3 weeks, weeds were turning yellow and purple. At 1 month, most weeds are dead or dying. - Stopped weed growth, but did not completely kill weeds like glyphosate and other non-selective herbicides. I cut the tops of the weeds off with the lawn mower about 2-3 weeks after application, and the weeds have not come back. Bermuda is now growing in areas where the dying weed stems are left. - Difficult to mix for small lawn. It did come with a handy measuring cup that helped with the small measurements, but i was still using 0.08 ounces for my entire lawn! You have to be very careful as it can kill treas and turfgrass at higher concentrations. - Does not kill Poa Annua
