The amount of surfactant you use with Celsius per gallon of water is going to depend on the brand of surfactant you use. It is recommended to use a non-ionic surfactant with Celsius. The two most common non-ionic surfactants we sell are Southern Ag Non-Ionic Surfactant or Hi-Yield Spreader Sticker. Please refer to the product page for each surfactant to determine how much needs to be mixed per gallon of water.
We recommend performing a small jar test and testing in a small inconspicuous area first. Celsius does treat many broadleaf weeds so it may not be necessary to apply two post emergent herbicides in the same tank or at the same time separately. Please provide your targeted weeds, desired turf and size area for additional assistance. We are happy to help!
Which herbicide is best for your needs will depend on several factors, including the type of turfgrass you have (Atrazine is for use only on Centipede and St. Augustine), the specific weeds you are targeting, and how large of an area you are treating. If you would like to provide some more details, then we are happy to make a product recommendation for you. Keep in mind that you do not want to apply post-emergent herbicides if your warm-season turfgrass is under stress from cold.
Weed growth ceases within hours after application of Celsius WG Herbicide. Symptoms progress from yellowing to necrosis resulting in plant death within 1-4 weeks after application.
