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.

    By Johnt in Prosper, TX on 05/25/2013

    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.

    By Glen in Moreno Valley on 02/27/2016

  • 5 of 5 stars  Poa Annua is dying
    By Dexter in Lexington, SC on 03/17/2015
    Verified Purchase

    It works as described. First time in 3 years I'm not seeing seed heads everywhere by this time. I did use a surfactant with my mixture. It has rained a lot this year so trying to spray in between has been a challenge. I also gave my grass it's one low cut for the year before applying. Other weeds in the yard turned black and died quickly. It will take a couple weeks for the poa annua to die.

  • 1 of 5 stars  Monument use on wild Bahia grass in FL. panhandle
    By Jeff in Pace, Florida on 11/09/2014

    Was excited about using this product since nothing I had used to date seemed to be able to slow the aggressive take over of my centipede lawn. Purchased the 5x5gm box and the surfactant, applied with two gallon sprayer as directed and applied at the recommended coverage rate. Has been 3 weeks and have seen absolutely no change in the Bahia grass. I am extremely dissapointed. I have two 5gm packets left and will go ahead and apply those as well, but judging from the initial results I have little in the way of expectations. For the extremely high price of this product I would have expected much, much, much better results!

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.

QHow do I kill both the grass and Nutsedge?
I want to remove my lawn to switch to edibles. Half of my lawn is nutsedge but I want to kill the grass too - and I want to reduce the health risks on the edibles I will grow in the future. I guess I will have to truck out all the soil and bring in fresh after chemical treatment??

AWe would recommend using a glyphosate product to kill the nutsedge and grass. It is a non-selective and will kill whatever you spray with it. You can replant after as little as two weeks after applying a glyphosate product.
