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.

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.

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.

We use a lot of Celius
By Matt on August 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 on August 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 herbicide review
By Jesse on July 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 on July 7, 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.

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.

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.

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.

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.
February 27, 2013
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.

Rodney from Royal Palm Beach, Fl asked:
QWhat are the mixing recommendations for Celsius WG?
I have a ortho dail N spary hose end sparyer that is 32oz how much should i mix in for a 1/8 of an acre with the sprayer dial at 1oz to a 2oz ratio
AThis product will not work well in a hose end sprayer because those sprayers are not accurate enough to apply the correct amount of product. You will need to use a hand pump sprayer and uniformly spray the product over the specified area.As 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.

QBayer's Celsius Has Little Effect oN Crabgrass
I have tried Bayer's product Celsius (WHICH YOU SELL) in my South Florida st aug lawn on post emergent crabgrass. It is my belief (and many others) that this product is falsely advertised. The only product that truly kills crabgrass is Asolux
Cesius is only labeled to control Large Crabgrass and there are other varieties such as hairy and smooth that are not on the label as listed weeds it will control. That could be why some are not having the success they would when using for the specific type of crabgrass they have. Unfortunately, we are unaware of a selective post-emergent herbicide to control crabgrass in a St Augustine lawn. St. Augustine is a very fragile grass, and so most selective products that are labeled to remove crabgrass and not harm your grass. It is recommended to kill the crabgrass with a round up type product, like GlyPhoSel Pro, which will also kill just the St. Augustine around the crabgrass that it is sprayed on, and then a couple weeks later re-seed those areas with new St. Augustine.
For long term control though, you should apply a pre-emergent in the late fall and early spring which will prevent new crabgrass from coming up next year. If you apply pre-emergent every year, you should not have issues with crabgrass long term. Dimension 2EW is one of our most popular pre-emergents for crabgrass.

Jimmy from Little Rock, Ar asked:
QIs Celsius WG Herbicide safe for dogs?
Do I need to wait a certain amount of time before I can let the dogs back into the yard?
A According the Celsius WG Herbicide label, you should keep children and pets off of the treated area until it has a chance to dry completely. This normally takes 2-3 hours depending on weather.

Neil from Fernandina Beach asked:
QHow long does it take for Celsius to kill doveweed in St. Augustine grace?
I applied Celsius five days ago. When should it take affect? Should I reapply?
A It could take 1-4 weeks in order for the doveweed to die completely. The speed will depend on varied temperatures and will be fasted in warmer temperatures. 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. A second application of Celsius can be made 2-4 weeks after the first treatment. Please let u sknow if you have any additional questions.

Ruston from Hertford,nc asked:
QCan you mix celsius, segment, prosedge and liquid fertilizer for weed and bermuda control in centipede lawns
A Celsius WG Herbicide may be tank mixed with other products. However, the ProSedge only recommends tank mixing with Glyphosate herbicides and unfortunately, Celsius is not a Glyphosate herbicide. If this product is to be tank-mixed with other products, compatibility should be tested prior to mixing. To test forcompatibility, use a small container and mix a small amount (0.5 to 1 qt) of spray, combining all ingredients in thesame ratio as the anticipated use. If any indications of physical incompatibility develop (precipitation, settling, changes in color), do not use this mixture for spraying. Indications of incompatibility may occur within 5-15 minutes after mixing. Read and follow the label of each tank mix product used for precautionary statements, directions for use, geographic and other restrictions. To further inquire about the compatibility of the Celsius with Segment and a liquid Fertilizer we recommend you contact Bayer for guidance. Bayer may be reached at 800-331-2867.

Ryan from Charleston Sc asked:
QIf I just put st Augustine grass down how long should I wait before applying Celsius?
I applied a small rate of Celsius to grass we laid four months ago and it appears to be killing the grass.
A The label does not specify how long to wait to apply Celsius to newly planted St. Augustine like it does for Bermudagrass and Zoysia Grass. We recommend contacting the local Master Gardner in your county here. There are a couple different factors that could be causing the grass do die and since they are in your county, they can be of great help.
