Product Overview

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.

    worth the price

    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.

    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.

    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.

Questions & Answers

Have a question about this product?
  
Q
You 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?

A
As 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.

Q
Is there an herbicide that kills Virginia Button Weed and does not harm St. Augustine grass?
A
Celsius 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.

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.

Q
Is 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?

A
According 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.
