CELSIUS WG Herbicide is a postemergent foliar-applied herbicide containing three active ingredients that provide a broad spectrum of weed control. This weed killer 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 Celsius Herbicide 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 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
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
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
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.

Is it toxic to humans & pets?
People and pets should be out of the area while applying Celsius WG Herbicide until it has a chance to dry completely. This normally takes 4-6 hours depending on weather. While it is not an insecticide to kill insects, they could be injured if sprayed directly. It would be best to apply when they are not in the area, early morning or later in the evening.

Our pest guy tells me that the herbicide he puts down (Celsius) can cause a fungus growth in St. Augustine grass. I am skeptical! I've had brown areas many times after he puts down Celsius. He kills my grass but not the weeds. What's going on?
Celsius Herbicide should not cause fungus in your lawn when used as directed on the product label. For more information, we would recommend contacting the manufacturer (Bayer) directly at 800-331-2867.
Do I need to wait a certain amount of time before I can let the dogs back into the yard?

In general the Celsius WG Herbicide is safe for people and pets so long as you keep them out of the area while applying the chemical, and until the product has had plenty of time to dry (normally a few hours). If your cat has any sensitivities we would recommend consulting your vet, otherwise the cat should be safe to eat the grass as long as its dry.

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!

The label does not limit the use of Celsius to temperatures below 85 degrees. There are cautions about using surfactants and also a note about the possibility of Celsius causing temporary stunting of St. Augustine grass in hot weather. If you read some of the popular lawn forums they actually claim Celsius works better the hotter it gets.
As long as the temperature during the application of the Celsius WG Herbicide 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. Temperatures over 85 degrees will cause extra stress on your desirable turf, possibly causing damage.

When do I need to stop using it?
The best time to use Celsius WG Herbicide or any other herbicide will depend on where you are treating and the specific type(s) of weeds you need to treat. Most post-emergent herbicides will be most effective when the target weeds are young actively growing. If you need help with identification or determining the best time to apply, you can call your local cooperative extension office and ask to speak to the master gardener on staff and he/she should be able to help you.
