Crabgrass will start to die after the first frost. Celsius is not a pre-emergent herbicide, so it will only affect crabgrass that is actively growing now and will not prevent future growth of crabgrass.
Yes, Celsius WG Herbicide is labeled for spurweed in sports fields and is safe for bermudagrass.
Per the Celsius WG Herbicide product label: MOWING INSTRUCTIONS: Do not mow immediately after treating with this product or before spray has dried. Typically you should 1-2 days before and after applying.
Most herbicides including Celsius WG are not as effective for weed control when the temperatures are below 55 degrees and the weeds are not actively growing.
The label states that you will have to wait 90 days before overseeding after treating with Celsius WG Herbicide. If you have already overseeding, wait until 4 weeks after seeding or after your second mowing to apply to newly sprigged grass.
It is recommended to wait 90 days to overseed after applying Celsius WG Herbicide.
If the new St Augustine lawn has started to become established or been mowed at least once you can carefully spot treat with the Celsius WG on the newly laid sod. Anytime herbicides are used its best to wait 4-6 weeks or until the grass has been mowed 1-2 times.
We would recommend storing Celsius WG Herbicide in it’s original container if possible as we do not have any information on transferring the product and the effectiveness and shelf life in another container. For more information, Bayer can be reached directly at 1-800-331-2867.
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 can be applied to established St. Augustine turfgrass as directed but it should NOT be applied to or near fruit trees. You should avoid applications within 15 ft of edible vegetation and outside the dripline of fruit trees.
Unfortunately, Celcius WG Herbicide should NOT be used on Bahiagrass or any other cool season turf grasses so we would not be able to recommend a reseeding time frame.
Unfortunately, most post emergent herbicides that target grassy weeds are not safe for use on bahia and would need to be spot treated directly with a non selective glyphosate product like Roundup QuickPRO. Any bare spots can be reseeded after 2 weeks.
For broadleaf weed control in bahiagrass, Ferti-lome Weed Free Zone would target many common broadleaf weeds and safe for bahiagrass.
View the Weed Free Zone product label for more information.
No, Celsius WG Herbicide is not safe to be used on Kentucky Bluegrass, it for use on warm season grasses only. You may want to consider something like Q4 Plus Turf Herbicide instead. Pre-emergents are applied in spring and fall dependingo n your area. You may consider signing up for our turf box, as it would send you pre-emergents when needed & for your lawn size to prevent some of the weeds from growing. Then in late spring/summer you can use a post-emergent to kill off the weeds that did germinate.
Celsius WG Herbicide is a selective post-emergent herbicide that is safe if used as directed to established centipede turf for targeting listed weeds including green foxtail and giant foxtail at 1.6 gm/1,000 sq ft and yellow foxtail at 2.4 gm/1,000 sq ft.n

Weeds, whether grassy or broadleaf, can take a few years to completely control.
No, Celsius WG Herbicide is safe on warm season lawns such as Bermuda. It will not harm it any way. Depending on what type of fescue you have, Gordons Ornamec 170 Grass Herbicide is labeled to control bermuda.
Please be advised that Bermuda grass is extremely difficult to control and you will likely need to make several applications no matter which product is used and multiple seasons at times. Best time to apply products to control it is in fall as it is starting to go back into dormancy or the spring when it is coming back out of dormancy.Some ornamentals may be sensitive to Celsius WG Herbicide and since it wasn't tested for use on ornamentals it is best to try and avoid spraying them with Celsius. We would recommend only spot treating weeds directly inside the dripline of trees/shrubs and avoiding any contact with exposed roots or the trees themselves.

Celsius WG Herbicide is a post-emergent so therefore it would not effect the seeds, it would only effect germinated seeds. If you are looking for a pre-emergent. You can consider Pendelum 2G Herbicide and verify with your local extension office for optimal timing for prevention on buttonweed in your area.
