Gallery 75DF (isoxaben) was initially registered in 1992 for ornamental horticulture uses. This initial label contained an extensive list of ornamental horticulture crops where Gallery could be used without causing phytotoxicity. It also included a short list of crops where Gallery applications were not recommended. Between 1992 and 2013, IR-4 examined 98 crop species / genera to expand this label to other crops, including several different fern species grown in field containers. Of these, 24 crop species exhibited no or minimal transient injury with 20 already placed on the Gallery label. Eight crops exhibited injury in this research: Astilbe sp., Athyrium filix-femina, Buddleia davidii, Dendranthema x morifolium, Digitalis purpurea, Echinacea purpurea, Stachys byzantine, and Thymus sp. A new formulation, Gallery SC, was tested between 2014 and 2019 to determine crop safety on 35 species / genera in 74 trials. Of these, two species, Chasmanthium latifolium, Juncus effusus, Leymus arenarius, Sorghastrum nutans, Sporobolus heterolepis, and Stipa sp. exhibited no or minimal transient injury; C. latifolium is already in the Gallery SC label.
