CELSIUS WG Herbicide is a postemergent foliar-applied herbicide containing three active ingredients that provide a broad spectrum of weed control. Celsius controls more than 120 annual and perennial broadleaf weeds and grasses in warm-season turf types, such as St. Augustinegrass, Bermudagrass, Centipedegrass, and Zoysiagrass. Celsius herbicide is not labeled for use on cool-season grasses.
Coming in an easy-to-use wettable granular formulation, this weed killer is intended for use on residential lawns, commercial lawns, golf courses, sports fields, parks, campsites, recreational areas, roadsides, school grounds, cemeteries, sod farms. After applying Celsius WG Herbicide, 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, 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.
Dallisgrass: Please note that Celsius 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

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.

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?

Calculating the labeled max/yr and my lot size, I figure one bottle would be 4+ years worth.
