Pydiflumetofen + Fludioxonil is a new fungicide being developed for the control of foliar and soil-borne diseases of environmental (aka ornamental) horticulture crops. The IR-4 Project completed 54 crop safety trials on 26 environmental horticulture plant species or genera from 2015 to 2018. In these trials, 23 species or genera exhibited minimal or no injury. Five species or genera (Antirrhinum majus, Begonia sp., Calibrachoa sp., Lupinus sp. and Petunia x hybrida) exhibited minimal or no injury in 3 trials (Table 1) and 18 species or genera exhibited minimal or no injury in the limited number of trials (one or two) for each crop (Table 4). It is recommended these plant species be added to the label.
