Product Details
Celsius WG, manufactured by Bayer, is a professional-quality herbicide designed for post-emergent control on annual and broadleaf weeds and grasses like St. Augustine. It has some residual activity to prevent certain weeds from germinating.
This easy-to-use herbicide comes in water-dispersible granules that must be thoroughly and uniformly mixed in water and applied as a spray. Each pack covers up to 2,000 sq. ft. at the highest application rate while also delivering lower phytotoxicity in areas with high temperatures.
Celsius WG provides broad-spectrum control of grassy weeds like crabgrass. Up to 3 active ingredients help cease weed growth within hours of application.
Tools Needed
Mix the product in a backpack sprayer or hand can to use Celsius WG.
How to Use
* Step 1: Determine how much Celsius WG to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet, then multiply them together (length X width = square footage). For acreage, divide the square footage by one acre (square footage / 43,560 sq. ft. = acres). For spot treatments, mix 0.057 to 0.113 oz. (1.6 to 3.2 grams) of Celsius WG per gallon of water per 1,000 sq. ft. Do not apply more than a total of 7.4 oz (210 grams) of product per acre (0.17 oz or 4.8 grams of product per 1,000 sq. ft.) per year.
* Step 2: Fill your sprayer tank with half the amount of water, add the appropriate amount of Celsius WG, and fill the tank with the remaining half of water. Shake the sprayer tank until the solution is well-mixed.
* Step 3: Spray the target weed, ensuring even coverage via the fan spray setting. Check back after 2 to 4 weeks, and if grassy weeds are still present, perform a second application. Do not mow immediately after treatment with this product or before the spray has dried. After treatment, do not transfer clippings to non-target areas. For best results, do not irrigate until the spray has dried.
Where to Use
Use Celsius WG on warm-season turf on residential and commercial warm-season lawns or commercial properties such as sod farms, sports fields, parks, campsites, recreational areas, roadsides, school grounds, cemeteries, and golf courses (minus golf course greens and collars).
Do not use this product on bahiagrass or cool-season turf types, including tall fescue, fine fescue, Kentucky bluegrass, perennial ryegrass, or creeping bentgrass.
When to Use
Spray Celsius WG when turf is established or 4 weeks have passed for newly established turfgrasses. Grassy weed control is more rapid when soil temperatures are above 65 degrees, soil moisture is adequate for weed growth, and weeds are not under environmental stress (e.g., drought).
Safety Information
Celsius WG is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product.
Do not allow people or pets to enter the treated areas until the spray has dried.
Special Considerations
It is advised not to use a surfactant during spot treatment on St. Augustine grasses because of the risk of damage it can cause to the turf.
