Monument 75WG Herbicide

Monument 75WG Herbicide, a sulfonylurea, is a selective post-emergence herbicide that controls a wide variety of weeds including the majority of sedges (nutsedge or nut grass), oxalis, green kyllinga, and multiple other species of broadleaf weeds and grasses. Use Monument 75WG Herbicide on warm season turf in commercial settings such as sod farms, commercial property management, and golf courses. Weed control by Monument 75WG Herbicide is greatly improved when the soil has enough moisture and weeds are actively growing.

Two Sizes:

0.5 gram WSP - individual 0.5 gram pre-measured water soluble packets. Toss the packet into two gallons of water in a backpack or handheld sprayer. Perfect for smaller jobs or ease of use - no measuring.

Box (5 x 5 gram packets) - 25 grams total - Great value. Perfect for bigger jobs and bigger areas.




The degree of control resulting from application of Monument 75WG is primarily dependent upon weed species, weed size at application, environmental conditions, amount of Monument 75WG applied, and growing conditions. Weed control is greatly improved when weeds have emerged, ample soil moisture exists, and weeds are actively growing, than when the soil is dry and weeds are under stress from lack of moisture.

Growth of susceptible weeds is inhibited soon after application of Monument 75WG. The leaves of susceptible plants normally turn yellow, red or purple after several days, followed by necrosis and death of the growing point. Complete plant death occurs 1-3 weeks after application, depending upon weed species, growing conditions, etc.

Monument 75WG controls weeds by inhibiting (stopping) a biochemical process that produces certain essential amino acids necessary for plant growth. The inhibited enzyme system is acetolactate synthase (ALS). Certain weeds species have naturally-occurring biotypes within the population that are resistant to ALS-inhibiting herbicides. Applications of ALS-inhibiting herbicides used alone in the same area(s) continuously over a number of years can lead to an increase within a weed population of the ALS-resistant biotype(s). This, in turn, may reduce the utility of ALS-inhibiting herbicides for controlling entire populations of that particular weed species. To prevent or delay a build-up of ALS-resistant weed species biotypes, weed management programs should include the use of appropriately registered herbicides, for use on turf and for control of these weeds, with different modes of action (MOA’s) within the same year, or sequential years. Hand weeding before weeds set seed may also be helpful in reducing the build-up and spread of herbicide-resistant biotypes.

    5 of 5 stars  No Moa Poa!
    By Johnt in Prosper, TX on 05/25/2013
    Verified Purchase

    Knocked down mature poa annua and dallisgrass in one treatment. Did not destroy Bermuda. Killed the poa and dallis enough for the Bermuda to move in unlike other herbicides which leave dead brown spots which have to be sanded, etc.

    5 of 5 stars  Patience
    By in La Quinta, CA on 08/27/2013
    Verified Purchase

    My rear yard backs up to a golf course and the course sometimes sprays Monument but never in the eight feet behind my yard. The nut sedge grass was dense behind my property line and some into my rear yard landscaping. Also in the last application of Monument by the golf course, they did not do a good job in spraying and there was still some nut sedge into the course. I sprayed the Monument in a very large area (2 gallons worth) and waited to see the nut sedge die. After several days, nothing and I was frustrated that maybe the golf course sprinklers had washed the Monument away. Then all of a sudden, after more than a week, the nut sedge is gone where I sprayed. It just takes Monument and patience.

    By Anonymous in Longs, South Carolina on 07/10/2013

    Monument 75w absoutely killed the nutsedge. I can tell and my neighbors can tell by just looking at the brown spots all over my bermuda lawn. The bermuda was not killed even if I sprayed it. Absoutely no damage to my bermuda, as a matter of fact, the nutsedge is brown and dead and the bermuda is growing right in the middle of the brown spots and doing extremely well and thriving.

    By in Murfreesboro, TN on 05/31/2013

    We used this on our bermuda grass which had many weeds, particularly sedge, growing in it. One application did the trick. We put one envelope in 2 gallons water along with 2/3 ounce surfactant. Needed three envelopes for our 1/3 acre yard. Definitely worth the price.

    5 of 5 stars  Best nutsedge product on the market.
    By Dean in Davidson, NC on 06/20/2016
    Verified Purchase

    After heeding the advice of a turf science professor at NC State I tried this product on my Zeon Zoysia which was laid last year. I just did my second round of spot spraying and this product does not discolor or harm the grass at all and the sedge shows sign of necrosis in about 5-6 days. Great stuff.

  • 5 of 5 stars  Effective for Poa annua
    By Tracy in Broken Arrow, OK on 04/24/2016

    I tried this product because of a problem with Poa annua. My normal weed killers purchased from big box stores were not effective at all; I came to find that's to be expected since Poa annua is not listed on their species list. Within a few days of application I thought the weeds were already impacted by evidence of stopped growth. Sometime during the second week after application I was sure of this. Sometime around the fourth week after application the Poa annua began turning yellow and really dying off. I applied Monument 75WG in combination with a non-ionic surfactant in early spring. I recently mowed for the first time after application and see that I might need one additional application for total eradication.

    takes about 3 weeks to work... 2 applications needed...does not harm Bermuda or Zoysia at all...San Augustine turns yellow but does not die..so sad our government took MSMA off the markt, cheap and worked very well for Bahia.This product will kill Bahia and nutsedge selectively.

    I was a little concerned when the package came in an envelope with .5 grams of product. However, I dropped in a 2 gallon spray tank and used on my Zoysia backyard and Bermuda front yard. Poa Annua was the primary issue and it wiped it out.

    4 of 5 stars  Monument Herbicide for Virginia Button Weed
    By Les in Baton Rouge, LA on 10/03/2013
    Verified Purchase

    I am using Monument primarily for Virginia Button Weed. I am getting about 70-80% kill rate on first application. Second application killed most all button weed in my test area. I sprayed the entire test area in early September. After 14 days weeds were starting to turn colors. I spot sprayed the areas that were not turning colors. After 30 days weeds are dark in color and definitely dying. Monument slowed the growth of grass in the entire test area. Grass is mostly Centipede & St. Augustine. Grass appears healthy, but is not growing. I will try Monument again next spring.

    By in Easley, SC on 07/21/2013
    Verified Purchase

    I mixed it in a 2 gallon sprayer with MSO to treat my newly seed zenith zoysia. It was spray two weeks after seed emergence without hurting my zoysia; however it caused some yellowing which most of it was gone in a couple weeks after application. It killed all my nutsedge, green kyllinga, oxalis, annual poa, and fescue (patches of the previous grass I had) on my newly seeded zenith zoysia.

    5 of 5 stars  Small Quantity Monument
    By in La Quinta, CA on 07/03/2013
    Verified Purchase

    I was very glad to see that Monument is now available in a smaller quantity, because it is the only herbicide I have found that will kill the Purple Nut Sedge!! Since Monument is so expensive, the golf course we live on does not always spray Monument behind our house, and the Nut Sedge moves into my landscaping area. For a number of years, I have tried to buy smaller quantities of Monument without any luck and I am extremely happy to see a 2 gallon quantity packet is now available. I have tried all other sprays, but Monument is the only spray I have found that does the job completely. DoMyOwnPestControl was great to work with and they shipped right away.

    I purchased this product to kill off some of the tall fescue and winter grass that is growing around some zoysia I sprigged last year. It killed some grass, but not much. Just doesn't appear to be very effective.

QDoes Monument 75WG Herbicide kill Poa Annua that is already growing?
Will it prevent future growth?

AMonument 75WG Herbicide is labeled for and will treat actively growing Poa Annua. A repeat application may be needed after 4-6 weeks. Since Monument 75WG Herbicide is a post Emergent, it may not stop Poa Annua from germinating.

QI live in South Carolina. Is it too late to put monument down in this heat or should we wait until it's cooler?
Some experts say it may turn grass yellow?

AMonument 75WG Herbicide is a post-emergent herbicide that should be put down when the weeds are already emerged. There are no limitations on weather. It should be used as directed by the label. Be mindful of the type of turf you have to avoid your grass being burned.

QIs Monument safe to use on Fescue? I'm in North Carolina and trying to kill POA!

AMonument 75WG Herbicide will kill Fescue grass. The best way to treat for Poa Annua is by using a pre emergent like Bensumec 4LF. This way you will prevent it from germinating. Bensumec can safely be applied to Fescue lawns.

It's in our lawn but I don't know what kind of grass we have and nothing I have used gets rid of the dallis and I see Monument can not be used here in CA.

ATo ensure we do not recommend a product that would harm your grass, we really need to know what type of grass you have. You can contact the Master Gardner at the Your Cooperative Extension office. The Master Gardner will be able to assist you with an identification.

QIs this herbicide good for paspalan grass?
we have used this herbicide in paspalan grass, its make too much demage in grass. i have big events in ground.How to recover the grass.

AWe apologize but we are unsure how to answer your question. You asked if the Monument 75 would be safe on Paspalan grass, then stated that you have already used it and that it is damaging your grass. What weed are you trying to control in your Paspalan grass? The only way to recover damaged grass is with time, providing extra nutrients to the soil with a fertilizer, or by temporarily "painting" the turf green to make it look healthy until it comes back.
