Celsius WG Herbicide

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 SYMPTOMS
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.

    4 of 5 Stars  worth the price
    By Rpc in Verified Purchase

    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.

    2 of 5 Stars  Turf damage warning - Bayer has issued product update
    By Scott in West Palm Beach, FL 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.

    5 of 5 Stars  Celsius WG Herbicide works great
    By Pete in Atlantic Beach, Florida on October 11, 2012
    Verified Purchase

    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.

    5 of 5 Stars  Creeping beggarweed in St. Augustine at bay house in Texas.
    By Betty in Houston, Texas on June 27, 2012
    Verified Purchase

    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.

    5 of 5 Stars  Celsius WG Herbicide
    By Christina in Cocoa, FL on December 3, 2014
    Verified Purchase

    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.

    By Matt in Jacksonville, FL 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.

    5 of 5 Stars  Works well on Centipede
    By Neal in Patterson, GA 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.

    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.

October 12, 2011 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.

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.

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.

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.

January 3, 2015 Tom from Tampa Florida asked:

QCelsius WG Herbicide product life
I bought this and the product was manufactured two years prior (according to the label on the container). I appears to lose effectiveness rather quickly, wherein I have to now double the dose to get some response. The weeds are in a new area, so it is not likely there is weed resistance to Celsius occurring. Can you provide guidance as to the increased rate of application with product age?

A 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. We no longer sell this product so any additional questions, we would recommend contacting the manufacturer, Bayer.

October 2, 2014 Mark from Palm Beach Fl asked:

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

A 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.
