Research Summary Abstract
Sultan (cyflumetofen) was registered for use on greenhouse ornamental horticulture crops as foliar sprays in the United States on May 9, 2014 to manage mites. The label does not contain a list of crops tested for tolerance. During 2014 and 2015, the IR-4 Project conducted 69 trials on 21 ornamental plant species examining phytotoxicity related to cyflumetofen applications. Only one crop (Impatiens walleriana) exhibited significant injury or growth reduction during these experiments.
