Per the Fusilade II product label instructions by the manufacturer:
For established turf, do not reseed desired grasses to treated areas for 14 days following the application. For bare ground areas which have been treated, wait 30 days to reseed.
Fusilade II Herbicide is not labeled to be used around edible vegetation or pumpkins.
Fusilade II Herbicide can be safely used in a non residential tall fescue lawn to eliminate crabgrass and suppress and control bermudagrass. Keep in mind crabgrass control this time of year is particularly difficult and may require multiple applications, and bermuda will take multiple applications as well due to how well it spreads. For a residential lawn, Gordons Ornamec 170 Grass Herbicide can be used to control Bermuda grass and crabgrass in fescue. Please refer to the product label for complete application instructions.
We are not aware of either product making grass more susceptible to frost damage, but Fusilade II Herbicide is a grass killer and is not labeled as safe to apply to Kentucky Bluegrass. While it is labeled for removing bermudagrass, this is only in Tall Fescue and Zoysia Lawns. It does state on the product label that it is not for use on home lawns as well. We would recommend reseeding the area.
Fusilade II Herbicide is not labeled to be used around edible vegetation. It can stand up to rain after only 1 hour of application. Allow product applications to completely dry prior to irrigation.
Fusilade II Herbicide will harm Kentucky Bluegrass. We recommend to spot treat with Roundup.
Depending on what you are trying to target the Fusilade II Herbicide is safe to be used on zoysia that is established whether it is actively growing or dormant. However, anything you may be trying to eliminate from the zoysia grass will likely not be affected by the Fusilade application if all of the plants are in a dormant state due to the time of year and ground temperatures. Fusilade is a post emergent herbicide and will only control grasses that are in a fully actively growing state. When you do apply the Fusilade, be sure to use a Non Ionic Surfactant for best results.
Per the Fusilade Product Label for use on Zoysiagrass:
Over-spray Zoysia: Application should be made at a rate of 3-4 fl oz/A with Fusilade II Turf and Ornamental Herbicide, and a nonionic surfactant. Applications should be made in late spring (around June 1) and repeated about every 28-30 days. Latesummer application can be reduced to 2-3 fl oz/A as bermudagrass is preparing for dormancy. During hot summer weather the rates could be increased to 4-5 fl oz/A. Note: The 5 fl oz rate could cause temporary turf discoloration.
Fusilade II Herbicide is safe to use over crepe myrtle, camelia, and many types of roses when used according to the product label. Be careful only to use a non-ionic surfactant and not a crop oil concentrate when applying Fusilade over the top of ornamentals.
While it is labeled for removing Bermudagrass only in Tall Fescue and Zoysia lawns, we do not recommend using Fusilade II Herbicide on your Kentucky Bluegrass as it is a grass killer and it's not labeled safe for it.
Fusilade II Herbicide should not be used on desirable turf as a broadcast spray. You can do a spot treatment in your lawn only. The mixing ratio is 0.75 fl. oz. per gallon of water. It is also recommended that you use a surfactact, such as the Non-Ionic Surfactant. The mixing ratio for that is 1/2 fl oz.
Fusilade II is labeled for use around iris and when used as directed should not harm them.
Fusilade II Herbicide could pose harm to Love Grass. It may be best to spot treat with Roundup.
We would not recommend spraying Fusilade II Herbicide within 10 feet of the bee hive. Avoid spraying when bees are active to prevent contact, so apply early morning or late evening.
Fusilade II Herbicide will also harm St. Augustine grasses. It may be best to spot treat with Roundup. Also consider reseeding/resod.
Updated Jan 2025: Fusilade is not labeled to be used on St Augustine for bermuda grass control when tank mixed with Recognition Herbicide. Following these instructions Recognition Herbicide 2(ee) Supplemental Label-St. AugustineFusilade II Herbicide can be applied to residential areas per the product label. Please refer to the product table for specific dilution ratios.

Fusilade II is not labeled as safe to be used on Centipede lawns. While it is labeled to target torpedograss, it requires multiple applications at the highest labeled rates, and offers suppression of bermuda. Bonide Grass Beater Over the Top Grass Killer, however, is labeled for use on centipedegrass and will target bermuda and torpedograss as well as many other grass species.
