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.

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.

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.

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.

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.

Anxious to try on Buttonweed
By in Prairieville,La on 08/26/2013
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
By in NE Atlanta, GA on 08/14/2013
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.

This company deletes posts that are not positive for their product. I have ordered and used this product. Show some ethics and post this.
This is not true. Just look around our site and you will see that we post negative reviews all the time.

Works on Creeping Beggarweed in St. Augustine Grass!
By Scott in West Palm Beach on 11/03/2012
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....

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.

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.
02/27/2013 Gary from Galveston, Tx.
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.
05/24/2012 C from West Palm Beach, Fl
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.
09/26/2014 Jimmy from Little Rock, Ar
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?
AAccording 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.
05/17/2014 Larry from Lancaster, Tx 75134
QWhat substance do you add to Celsius WG for it to kill weeds?
AThe Celsius on its own will kill the weeds as that is what it is designed to do as an herbicide. If you want accelerated control you can mix a surfactant with the product for better stick.

QWhat can I use to kill dove weed in a St. Augustine lawn?
02/10/2013 Jane from Jax Fl
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?
ACelsius 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.

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. 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.
10/27/2012 Charles from Sebring
Qhow often can you put celsius down on your lawn
AFor certain weeds, a second application made 2-4 weeks after the initial application may be needed for complete weed control. Total amount of product applied in a calendar year (365 days) must not exceed 7.4 oz (210 g) of product per acre.
05/16/2012 Danny from Sugar Land, Texas
QWill Celsius WG Herbicide work on Bermuda Grass in the South, without killing it?
ACelsius is labeled for use on Bermuda grass to control large crabgrass and should not harm the Bermuda as long as you follow the product label.

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.
