The Fusilade II is for use in ornamental and flower bed areas primarily, whereas the Fusilade DX is labeled and formulated in a way that is for use on many edible crops that the Fusilade II does not cover on its label.
Per the product label for Fusilade DX Herbicide do not apply more than a total of 30 oz per acre per year.
Fusilade DX Herbicide is not safe for either turfgrass type (TTTF or KGB) as stated on the product label that is should NOT be applied to TTTF and KGB. These turfgrasses are not listed at all and it is more for commercial/agricultural areas.
Acclaim would be an alternative post emergent for bermudagrass in TTTF/KGB. A non ionic surfactant should be used in the tank mix for best results with Acclaim.
Please be advised that Bermuda grass is extremely difficult to control and you will likely need to make several applications.
