Trade and Other Names: Trade names for products containing fluazifop-p-butyl include Fluazifop-p-butyl ester, Fusilade 2000, Fusilade DX, Fusilade Five, Fusilade Super, Fusion, Horizon, Ornamec, PP005, and Tornado.

Regulatory Status: Fluazifop-p-butyl is a slightly to practically nontoxic compound in EPA toxicity class IV [1,2]. It is a General Use Pesticide (GUP), and labels for products containing it must bear the Signal Word CAUTION.

NOTE: This profile is for fluazifop-p-butyl herbicide, which is a different compound than either fluazifop-p or fluazifop butyl. Fluazifop-p-butyl is the n-butyl ester of the acid Fluazifop-p. Fluazifop-p is the R-enantiomer ("dextro" or "plus") of the acid, while Fluazifop typically contains equal proportions of both the R- and S-enantiomers [2,3]. Fluazifop-p (the R-enantiomer) is the herbicidally active portion of the mixture.

Chemical Class: phenoxy compound

Introduction: Fluazifop-p-butyl is a selective postemergence phenoxy herbicide used for control of most annual and perennial grass weeds in cotton, soybeans, stone fruits, asparagus, coffee, and others. It may often be used with an oil adjuvant or nonionic surfactant to increase efficiency. It has essentially no activity on broadleaf species. It is compatible with a wide variety of other herbicides and may also be found in formulations with other products such as fenoxaprop ethyl ester (in Horizon and Fusion) and fomesafen (in Tornado). It is available as an emulsifiable concentrate. Fluazifop-p-butyl formulations may contain some fluazifop-butyl.

Formulation: It is available as an emusifiable concentrate. Fluazifop-p-butyl formulations may contain some fluazifop-butyl.
