Product Overview

CELSIUS WG Herbicide is a post-emergent herbicide designed to tackle a broad spectrum of tough weeds in warm-season turfgrasses.  Containing three active ingredients, this foliar-applied weed killer controls more than 120 annual and perennial broadleaf weeds and grasses.  Celsius herbicide delivers effective weed control in St. Augusitinegrass, Bermudagrass, Centipedegrass, Zoysiagrass and Buffalograss.

Coming in an easy-to-use wettable granular formulation, Celsius WG Herbicide needs to be mixed with water before applying. It can be used on residential lawns, commercial lawns, golf courses, sports fields, parks, campsites, recreational areas, roadsides, school grounds, cemeteries, sod farms.  Celsius can be used to control weeds such as dollarweed, doveweed, crabgrass, Virginia buttonweed, dandelion, bull paspalum and many more.

After applying Celsius weed killer, weed growth ceases within a matter of hours.  The weeds will progress from yellowing or turning red or purple to necrosis, resulting in the plant death within 1 to 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, you should apply Celsius WG when the daily average temperature is above 60° F.   Applications of Celsius Herbicide should be made to actively growing weeds.  Weed control may be reduced if applications are made in the presence of heavy dew, fog, and mist/rain or when weeds are under stress due to drought.

Dallisgrass:  Please note that Celsius herbicide is labeled for suppression of dallisgrass only and can only be used for dallisgrass when tank mixed with another herbicide such as MSMA or Revolver (which are not for residential use).

    worth the price

    By Rpc on 12/12/2011

    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.

    Turf damage warning - Bayer has issued product update

    By Scott 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 on 10/11/2012

    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.

    Creeping beggarweed in St. Augustine at bay house in Texas.

    By Betty on 06/27/2012

    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.

Q
How many applications (gallons) does a bottle of Celsius make?

How many applications (gallons) can you get from a single bottle of Celsius?

A
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.

Q
What 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.

A
Celsius 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.
