Research Summary Abstract
Pydiflumetofen + Difenoconazole is a new fungicide being developed for the control of foliar diseases of environmental (aka ornamental) horticulture crops. The IR-4 Project completed 24 crop safety trials on 11 environmental horticulture plant species or genera during 2019 to 2020. In these experiments, no injury was observed across crops. It is recommended that three crops exhibiting no injury be added to the label: Chrysanthemum/Dendanthemum sp, Impatiens hawkeri, and Viola wittrockiana.
