CELSIUS WG Herbicide is a postemergent foliar-applied herbicide containing three active ingredients that provide a broad spectrum of weed control. This product is intended for use on residential lawns, commercial lawns, golf courses, sports fields, parks, campsites, recreational areas, residential lawns, roadsides, school grounds, cemeteries, sod farms to control annual and perennial broadleaf weeds and grasses in warm-season turf types listed on this label.
Weed growth ceases within hours after application. Symptoms progress from yellowing to necrosis resulting in plant death within 1-4 weeks after application. The speed of symptom development varies with temperature and will be faster at warmer temperatures. For best results to control mature weeds, apply when the daily average temperature is above 60° F. Make applications to actively growing weeds. Weed control may be reduced if application is made in the presence of heavy dew, fog, and mist/rain or when weeds are under stress due to drought.

worth the price
By Rpc in
Was hesitant to buy given the price but the Floratam lawn was being overrun with weeds, dollar weed in particular. The product has worked well - kills the weeds without harming the lawn. Only a small amount of the product is needed to create a gallon of spray so the cost will be amortized.

Turf damage warning - Bayer has issued product update
By Scott in West Palm Beach, FL on 06/20/2012
Following the label directions for spot treatment caused moderate and even some small spots of severe damage with clumps of grass (St. Augustine) falling out at the crown. In the update Bayer now recommends against surfactant for spot treatment. Basically, spot treating is not worth the risk due to damage from higher application rates as you focus the spray. The good news is my grass seems to be slowly recovering and the dollarweed and beggarweed were killed within days. The label lists kyllinga but it is still alive where the grass has died back. One weed which Manor/blade kills but this does not is Asiatic Dayflower. I have had some luck getting this to knock back blanket crabgrass but it grows back.

Creeping beggarweed in St. Augustine at bay house in Texas.
By Betty in Houston, Texas on 06/27/2012
Creeping beggarweed was taking over my St. Augustine grass at my bay house in Rockport, Tx. Other herbicides I tried did not even phase this weed. I followed the mixing instructions in 1 gal. sprayer with the sufficant added. I used about 6 gallons initially on June 15th and within 5 days the beggarweed was dead or dying. I mixed another gallon this week and spot sprayed the weed where I missed the first time. Thank goodness Celsius kills this obnoxious interloper. Of course, I would like it even more if it was less expensive but under the circumstances I was thrilled to find something so effective on this pest.

Celsius WG Herbicide works great
By Pete in Atlantic Beach, Florida on 10/11/2012
It seems like this has worked really well on my lawn trying to get rid of Dollarweed. I've tried Atrazine and Image in the past with minamal results. It did not hurt my Saint Augustine grass at all. I would definitely recommend this product. The only thing I would say is that a 10oz bottle is probably a 10 year supply. So I sprayed my neighbors yard and my mother-in laws yard as well.
Death to Virginia Buttonweed
By Ed in Houston on 07/25/2017
This stuff is like Dirty Harry...it made my day. Has killed the Virginia Buttonweed in my recently sodded Palmetto St. Augustine lawn and the grass is doing fine. I did notice that the grass is not growing as fast as before, but that is noted in the literature and should be temporary (Celsius has two means of killing, one of which interrupts the growth process). I highly recommend that everyone in the world buy it and make buttonweed extinct.

Celsius WG Herbicide
By Christina in Cocoa, FL on 12/03/2014
We live on the eastcoast of central Florida on a sandy ridge. I applied this herbicide around 11/1 while the daytime temps. were around 80-85d F. I did a spot application in the late evening (large areas but not the entire lawn). I just surveyed the lawn and notice about an 70% reduction in the weeds I sprayed. Some weeds completely shriveled up and died, leaving bare spots. I still see some stubborn yellow dollar weed hanging in there, but most of them are gone too. Some crabgrasses didn't budge. None of my lawn got damaged, even the areas that got a double spray (I ran out of daylight and mixture one day and started again two evenings later and overlapped some areas). I am satisfied with this product and will continue using it. The granules dissolve easily and I didn't have any trouble with clogging etc. I did use a non-ionic surfactant.

We use a lot of Celius
By Matt in Jacksonville, FL on 08/27/2014
I use this product professionally with my lawn service company. It is great because it will kill just about every broadleaf weed when applied with a MES100 properly. I've only had trouble with chamber bitter, everything else is gone without harming St. Augustine.

Works well on Centipede
By Neal in Patterson, GA on 08/18/2014
I applied this at the highest rate in the July heat of south Ga. My centipede was well watered and growin and did not show any stress from the application. I have Chamber Bitterweed, Doveweed, and Florida Betony, Bahia, and other unidentified weeds. The Bitterweed show the effects within a couple of days as did the Betony. The Doveweed and Bahia took a couple of weeks. I highly recommend this product bc of it's ability to use it in the heat on the sensitive warm season grasses.

Celsius is HOT!
By Barbara in Upstate SC on 07/24/2014
This is the best thing I have found for control of crabgrass in Bermuda and Zoysia! Works best in combo with granular slow release (something containing Dimension). Now, if only it kills poison ivy living in Juniper...

celsius herbicide review
By Jesse in Troy, Alabama on 07/11/2014
The Celsius herbicide works well, however it kills some of the grasses it is labeled for use with.. I recently used it on an a mixed yard of Bermuda, St Augustine, and centipede. Lost some of all three of the grasses that I was trying to remove the other grasses from.

One of the best herbicides for St Augustine grass
By Somebody in Florida on 07/07/2014
Kills almost every kind of weed in my St Augustine grass and I can apply it when the temperature is hot. The 10 ounce bottle should last for years.

QYou indicate not to spray Celsius above 85 degrees.
Can Celsius be sprayed at 85 degrees even the temperature is rising and will be above that in an hour or two? In other words can I spray in the morning when it is 75 degrees and an hour later the temperature is over 85 degrees?
AAs long as the temperature during the application of the Celsius is not 85 degrees or above, then it does not matter what temperature it reaches mid day. The best time to apply herbicides is either early morning when dew is still fresh on the ground or late afternoon when the lawn and weeds are under less stress from the environment. The less stress the weeds are under the better they will absorb the product being used.

QIs there an herbicide that kills Virginia Button Weed and does not harm St. Augustine grass?
ACelsius Herbicide is the most recommended product to treat Virginia Buttonweed in St Augustine grasses. Virginia buttonweed is notoriously hard to control and may require a second application after 2-4 weeks.
10/12/2011 Matt from Oviedo, Fl
QHow many applications (gallons) does a bottle of Celsius make?
How many applications (gallons) can you get from a single bottle of Celsius?
AAs with most herbicides the exact volume of water is not very important, you just need to be sure you are getting the correct amount of product on a specific area. Celsius may be applied at three different rates depending on the weeds to be controlled. For the appropriate rate and species consult USE RATES FOR WEED CONTROL section on the Celsius product label. For spot applications, add the specified product rate of 0.057-0.113 oz (1.6-3.2g) to enough water to create approximately 1 gallon spray solution. One gallon of spray solution will treat up to 1,000 sq ft. For maximum weed control with broadcast applications, add non-ionic surfactant.

QWhat is the shelf life of Celsius WG? How long is the shelf life in a typical hot garage?
Calculating the labeled max/yr and my lot size, I figure one bottle would be 4+ years worth.
ACelsius should not be stored in a hot garage. Storing chemicals in hot temperatures will degrade the active ingredient and greatly reduce the efficacy of the product. When stored properly, out of extreme temperatures and out of direct sunlight, you can expect Celsius to last for about 3 years from the date of purchase.

QCan Celsius WG Herbicide be used in temps of 85 or over?
I live is south florida and during the rainy season, weeds propogate. Most herbicides indicate they should not be used in temps over 85.
ACelsius, like most herbicides should not be used in temperatures 85F degrees and over.

QHow soon after you apply the Celsius WG can you expect to see the weeds die?
Do you need to water it in after applied? Wetting agent necessary?
A Depending on the weed you're treating, it could take anywhere from 1-4 weeks for you to see results with Celsius WG Herbicide. Weed control may be reduced if application is made in the prescense of heavy dew, fog, and mist/rain or when weeds are under stress due to a drought. For best results, do not irrigate until spray has dried. For maximum weed control with broadcast applications, add a non-ionic surfactant.
