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.

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.

No Moa Poa!
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.

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.

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.

Poa annua control
By Mike in Pinehurst, NC on 04/19/2013
I had a good deal of poa in my bermudagrass lawn. I spot sprayed with Monument. It took a few weeks but it killed all of the poa, some of it was rather mature. I will definitely used it again if needed.
By Zhiguo in Frisco, TX on 05/16/2016
Almost 2 weeks now after application. Poa annu start to die, and also other weeds start to show symptom of injury, my Bermuda still looks good. This is a good product.
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.

Not so good
By Glen in Moreno Valley on 02/27/2016
I ordered this product to eradicate my Poa Annua grass ,in my lawn. I followed directions and sprayed the the area. It's now three weeks and I see no change. Twenty dollars for no change hardly seems worth it.
Great service, quick delivery
By Aloo in Fort Mill, SC on 01/23/2016
I saved a bunch of money and got the chemicals I needed within a couple of days. I'll order more products from DMPC in the future.
By Chuck in Shirley AR on 08/11/2015
Works and is still working as advertised. The what we call peanut grass is dying off.
By Jb in Canton, GA on 04/24/2015
I was very happy with the order process, time for fulfillment/ delivery, and the product results were outstanding. First product I have been able to find that effectively removes Poa Annua from bermudagrass.
Poa Annua is dying
By Dexter in Lexington, SC on 03/17/2015
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.
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!
I got less than expected results
By Ken in Chattanooga tn on 08/26/2014
I use this on relatively new zoysia got poor results . I followed the instructions exactly killed some ragweed. Gave it 1 star as it would not post with no stars
Zoysia South Louisiana
By Ka in Northshore NO, LA on 08/21/2014
Used on Zoysia in S. LA in July. Had a problem with green kyllinga that would sprout faster than I could pull it and it threatened the entire lawn. Followed directions and added a surfactant that I bought here, as well. I may have gone a little thin (covered too much lawn). I didn't see any results for a couple weeks and I didn't see the dramatic color change of the kyllinga that some report but I did see some of its sprouts die and then it all disappeared a few weeks later.

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.

QDo I need a surfactant when using Monument?
AYou do not have to use a surfactant with Monument, however the label states you can mix in a nonionic surfactant to help the Monument to stick and penetrate the weeds.

Crabgrass has overrun 50% of the lawn. It has been dry in Oregon and my lawn was overrun.
A Monument 75WG is labeled to suppress†crabgrass only but is normally not the recommendation. †Suppression means significant activity, but not always at a level considered acceptable for commercial weed control.

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.
