The seeding interval will vary depending on what type of turf you have. To rake you should wait until the weeds are completely dead. You should review the product label for specific directions for your turf. For example:
"Seeded Bermudagrass: This product may be applied to Bermudagrass up to 90 days prior to seeding without a significant reduction in Bermudagrass stand."
"Seeded Zoysiagrass: This product may be applied to zoysiagrass up to 90 days prior to seeding without a significant reduction in zoysiagrass stand."
Celsius WG Herbicide is for use only on warm-season grasses, so if you have a cool season lawn, then this product would like damage or kill it. When used as directed it would not harm the lawn.
If you are treating 3 acres, that is a total of 130,680 sq feet. If applying at the high rate of 0.113 oz per 1,000 sq ft, you would use a total 14.75 oz of Celsius WG Herbicide.
Per the product label for Dallisgrass Control: This product in combination with REVOLVER® Herbicide (2 fl oz per gallon) and MSO at 1% v/v applied as a spot treatment in late summer or early fall will suppress and/or control dallisgrass. Applications made sooner may not be effective. Add the specified product rate of 0.085 - 0.113 oz (2.4 - 3.2 g) to enough water to create approximately one gallon of spray solution. One gallon of spray solution will treat up to 1,000 sq ft. Make a second application if regrowth is observed 30-60 days later, but do not exceed 0.17 oz (4.8 g) of product per 1,000 sq. ft. in a calendar year
Celsius WG Herbicide is not labeled to be applied where animals there are grazing animals or livestock.
Please view our Range and Pasture Page for products labeled to be used in areas where grazing animals or livestock may be present. Review the individual product labels to ensure proper application methods are followed.
Celsius WG Herbicide will not work well in a hose end sprayer because those sprayers are not accurate enough to apply the correct amount of product. You will need to use a hand pump sprayer and uniformly spray the product over the specified area. 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.
Celsius WG Herbicide is not labeled to be used on fescue (tall or fine fescue) Per the product label, "Do not use this product on bahiagrass or cool-season turf types, including tall fescue, fine fescue, Kentucky bluegrass, perennial ryegrass, or creeping bentgrass".
The product label does give a 28 day interval if overseeding Bermuda with Ryegrass however we would recommend contacting Bayer directly for questions regarding seeding with fescue. Bayer can be reached at 1-800-331-2867
Avenue South Broadleaf Herbicide would be a better option for use on Fescue.
Celsius WG Herbicide is not labeled for basketweave/basketgrass.
Unfortunately, there really are not a lot of options for treating basketgrass. It should be spot treated with a non selective herbicide, and then reseed/resod in those areasFor maximum effectiveness, Celsisus WDG should be kept at room temperature. Storing chemicals in cold/freezing 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.
Yes, Celsius WG Herbicide is safe for Zoysia Grass when used as directed per the product label. Please view the Use Rates for Weed Control Chart on page 4 of the product label.
Celsius WG Herbicide works best when soil temperatures are above 65 degrees per the product label. Symptom development may be slow in weeds treated under cool conditions (soil temperatures 65 degrees or less)
Celsius WG Herbicide is labeled as safe to use on centipede during any dormant/growing season for actively growing weeds.
The product label does advise that weed control is more rapid when soil temperatures are above 65 degrees and slower when soil temperatures are below 65 degrees.
No, Celsius WG Herbicide does not need to be additionally watered in after the application has dried and should be applied using a sufficient volume of water to evenly and thoroughly treat 1000 sq ft.
View our How to Calibrate Your Sprayer Video for a short tutorial on how to determine the water volume needed for your property.
Per the product label, applications should be made when rainfall or irrigation is not expected for 48 hrs to prevent runoff of the application.
Celsius WG Herbicide is labeled to kill several species of clover however per the product label, if weeds are showing signs of recovery, make a second application 2-4 weeks after the first treatment.
In areas where weed pressure is high and adequate coverage is critical, add a non-ionic surfactant (NIS) and weeds will be better controlled when temperatures are between 65 to 85 degrees.
Celsius WG Herbicide will not control poa annua (annual bluegrass).
For warm season turfgrass, Certainty Herbicide is labeled for killing poa annua when actively growing. This post emergent should be used with a non ionic surfactant for best results.
Please review our Poa Annua Treatment Guide for more information.
Celsius WG Herbicide is labeled to control for both carpetweed (Indian Chickweed) and creeping beggarweed at the rate of 0.057 oz per 1000 sq ft. This product is also labeled to control ground ivy but DOES NOT list English Ivy as tolerant or safe for applications.
We would recommend doing small test application first or directly applying to the carpetweed/beggarweed without overspray or contact with the desired English Ivy.
View the full product label for more information.
We would recommend applying the pre emergent first as pre emergents need to be watered sufficiently into the soil to help stop the weeds from germinating.
Celsius WG Herbicide can then be applied to control actively growing weeds after the pre emergent application has dried.Celsius WG Herbicide is not labeled to control Bahia grass but it does advise not to be used on this grass type. While it could possibly injure the bahiagrass, we cannot say for certain it would fully control it.
Please view the product label for more information.
Generally, we advise a wait time of at least one year before planting edible vegetation in an area that has been treated with a residual herbicide, such as Celsius WG Herbicide. However, you may wish to contact the manufacturer directly for technical support by calling 1-800-331-2867.
Celsius WG Herbicide does have different wait time on the label for seeding but it does not list one for centipede grass. Please contact the manufacturer in regards to your concern. You can reach Bayer by calling 800-331-2867.
