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.

    By Lee in Frisco, Texas on 05/19/2017

    I used 1 packet for 2 gallons of water and sprayed 1,000 sq. ft. with it. Did not completely kill the poa annua. Bought 2 packets which cost me about $45. Will not use again as I did not get good results. Kinda of a waste of money. Overall a disappointment.

  • 5 of 5 stars  Monument results
    By Archie in Fortson, Ga on 05/19/2017

    I was looking for something that works on poa anna (annual blue grass). I had tried many post-emergents and none worked. Looking on YouTube someone claimed to have good results with Monument. So I ordered it from DoMyOwn. Monument worked as advertised. Three days to start seeing the browning and about two weeks for complete kill. It is the only thing that I found that really works on poa anna.

    5 of 5 stars  No more poa annua!
    By Shannon in Woodstock, GA on 05/08/2017

    I have a bermuda lawn that was being overrun by poa annua (annual bluegrass). I read online that once the bermuda comes out of hibernation, there's not much you can do to control the poa. Well, Monument 75, while it doesn't explicitly state it, took care of the poa! I'm beyond happy. No more ugly seedstalks mucking up the bermuda. There's still a little bit of poa, but the bermuda is now choking it out. Thank you, Monument 75!

  • 4 of 5 stars  Works, but very expensive.
    By Id2635 in Atlanta, GA on 05/02/2017

    It works great against Poa Annua, however it is very expensive. The Poa turns yellow and will no longer grow to full height after application. You should make sure to use pre-emergent the following fall to check future Poa Annua outbreaks!

    By Forrest in Horseshoe Bay Texas on 04/04/2017

    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.

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.
