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).

- Single Dose 0.226 oz pack - treats up to 2k sq ft. at the high rate and 4k sq ft at the low rate

Number: 79714858) EPA Registration 432-1507 How Much Celsius WG Herbicide Per Gallon of Water?
For spot treatments, mix:
- 0.5 teaspoon per gallon of water for light to moderate weeds
- 1 teaspoon per gallon of water for heavy or tough weeds
- Covers up to 1,000 sq ft
This matches the label rate of 0.057–0.113 oz (1.6–3.2 g) per 1,000 sq ft.
Focus on applying the correct amount per area, not exact water volume. Always read the label and follow all instructions before applying. Add a non-ionic surfactant for better control of tougher weeds.
How Much Surfactant Do You Use with Celsius WG Per Gallon?The exact amount of surfactant to use depends on the specific product. Always use a non-ionic surfactant with Celsius WG for best results. Check the surfactant label for the exact mixing rate.
Surfactants help the herbicide spread and stick to weeds, improving control, especially on tougher species. Using the right surfactant rate alongside Celsius WG helps maximize performance and ensures more effective post-emergent weed control.
How Long Does It Take Celsius WG to Work?Most weeds begin to show control in 1-4 weeks, depending on the species. Results may take longer if weeds are stressed (drought, heat, etc.).
For best results, allow the spray to fully dry before irrigating. Avoid applying Celsius WG during rain, heavy dew, fog, or mist as these conditions can reduce effectiveness.
What Turf Can Celsius WG Herbicide Be Used On? (Turf Tolerance)
Celsius WG Herbicide has been tested and can be used on the following types of turfgrass and their cultivars:
- St. Augustinegrass (Floratam, Palmetto, Bitter Blue, Common, Amerishade, Raleigh, Sapphire, Delmar, Captiva)
