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 on December 12, 2011
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 on June 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 on June 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 on October 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.

Anxious to try on Buttonweed
August 26, 2013
Just ordered some and a scale to measure grams and oz. so we can apply properly. All feedback is great online and this 28 yr. battle may be somewhat over. Buyers please note Update from Bayer on ionic surfactant in spot treatments. This is encouraging news for us lawn freaks. I gave it 5 stars out of pure optimism. Fingers crossed.

Celsius WG Herbicide works well
August 14, 2013
I ordered this product because I had a severe breakout of crabgrass in my Bermuda lawn due to the unusually wet spring and summer we are having in NE Atlanta. After 1 application the crab grass (and other weeds) is completely gone, I will apply one more treatment just to make sure, but I would highly recommend this product.

Hope it is GREAT

Sprayed Florida Betony, and died in about 3 days. This is a winter weed, so I hope it doesn't come back next winter.

I bought this and it works great on St Augustine grass where Atrazine appears ineffective.

Celsius for Floratam, St. Augustine grass
By Steve on March 11, 2013
I applied Celsius 2 1/2 months ago and all my weeds are dead or dying. The Floratam is continuing to grow with very little affect on it. I am very pleased

I applied Celisus to my property on January 10 and again on January 25. The reason for the double application was the number of weeds that were on the property under the bushes. I made sure to follow the directions as to the amount to use and kept under the requirements. I think it is working but will not be sure until I have given it at least three weeks from the last application. I am hoping for the best!

Works on Creeping Beggarweed in St. Augustine Grass!
By Scott on November 3, 2012
I was looking for something to kill Creeping Beggarweed in St. Augustine grass. This does work, although it's tough on the St. Augustine (which stopped growing for about 3 weeks) and if you don't get enough on the Beggarweed, it won't kill it, so concentration and dosing are critical. It doesn't work fast....3-4 weeks, so you can't be in a hurry. It also killed a few other weeds that I have, such as Green kyllinga and dollar weed, though there are products that will work on those weeds that are kinder to the St. Augustine. It hurt, but did not kill the asiatic dayflower. One surprising thing I found out is that it kills Asparagus "fern" (Asparagus densiflorus) which can be a problematic weed around here, especially in hedgerows....

Matt from Oviedo, Fl asked:
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.

C from West Palm Beach, Fl asked:
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.
May 24, 2012
Seth from Orlando,fl asked:
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.

Gary from Galveston, Tx. asked:
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.

Jeff from Lake Worth, Fl asked:
QDoes Celsius WG Herbicide kill creeping beggarweed?
these are the half moon shaped little green stickers that stick to you socks. It's a vine like weed that weaves its way through all my grass!
ACelsius is labeled for creeping beggarweed and when used as directed on the product label will do a great job helping you eliminate this pest weed.

Byron from Sarasota,fl asked:
QI am looking to buy Celsius WG Herbicide and see it comes in a 10 oz. size and the cost is over $100.00. I am trying to see how much is used in one gallon of water.
For spot treatments applying Celsius WG Herbicide, you can 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. Please refer to the product label for specific application instructions.

Tom from Orlando, Fl asked:
QWhere can I find a crabgrass control as good as Asulox on St. Augustine grass?
Celsius is labeled to eradicate crabgrass and dallisgrass as a post emergent in most St. Augustine lawns. You can purchase it right from our website here.

Bill from Pawleys Island, Sc asked:
QCan Celsius WG be sprayed directly on fakahatchee grass?
Celsius WG Herbicide cannot be applied on or near fakahatchee. It would most certainly harm it. Please let us know what type of weeds you trying to control. You can also contact your Master Gardner through your extension office for recommendations on what products are effective in your area.

QWhat can I use to kill dove weed in a St. Augustine lawn?
August 5, 2013
Danny from Ft Lauderdale Florida asked:
QWill Celsius WG harm fruit trees or vegetables?
A Celsius WG is not labeled for use on fruit bearing or nut bearing trees and vegetable gardens. How hurtful to the actual fruit trees and vegetables this may be we are unsure of. The main product used for weeds in a vegetable garden is a Roundup type product, like our RoundUp QuickPro product. Roundup Professional products do not leave a residual that could possibly be soaked up by the roots of your garden. Of course you do not want to get the RoundUp product on any plants you want to keep. You should only direct it at the weeds you want to get rid of.

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.

Tom from Florida asked:
QWhy does my bottle of Celsius have a two year old manufacture date?
I purchased this expensive bottle from your site and shortly after I noticed the manufacturing date was two years prior. In another answer you say the shelf life is three years. Will you be considerate and make good?
We apologize for any confusion. We do recommend that customers use their product within 3 years of the date of purchase because it can take a while from the date of manufacture for the product to be sold. The manufacturer warranties their product for 5 years from the date of manufacture. You can confirm this with the manufacturer. You can reach Bayer by calling 800-331-2867. Please let us know if you have any questions or further concerns. we are always happy to help.

Ed from Central Florida-orlando Area asked:
QWe have a variety of Stinging Nettle called Heartleaf Nettle/Fireweed in St. Augustine. Will Celsius work?
This weed laughs at 2 4d and Atrazine. Even Roundup only browns. If not Celcius, can you recommend another treatment that does not kill St. Augustine?
A Since St Augustine is so sensitive we are checking with some industry experts to see what they recommend as the best product for your specific needs. We hope to have more information for you tomorrow.
March 31, 2013
Kevin from Columbus,ga asked:
QWill Celsius harm other plants like forsythia, azaleas, bulbs and/or trees?
A Some ornamentals may be sensitive to Celsius and since it wasn't tested for use on ornamentals it is best to try and avoid spraying them with Celsius. Do not plant ornamentals or bedding plants in treated bare areas for at least 30 days after the last application of this product.
February 10, 2013
Jane from Jax Fl asked:
QIs there a better way to measure Celsius WG other than the cup that comes with it?
the measuring cup that comes with the product actually starts at 0.17 ounces. That is the MAX per year for 1000/ft .... it recommends 0.057 ounces and thats not on measuring cup. Am I missing something? Why such a large cup to measure when that mark you need isnt on it?
A Celsius is a professional product and the manufacturer does gear it toward the professional applicator, including the measuring cup. Unfortunately we have no control over this because we do not manufacture the product. Our other customers have told us that they have been able to get small medicine syringes from the pharmacy to measure the smaller amount that they require.
