Pydiflumetofen + Azoxystrobin + Propiconazole was a new fungicide being developed by Syngenta for the control of leaf spots (Septoria, Cercospora, Alternaria, Venturia), powdery mildew, Fusarium, Botrytis, Sclerotinia, Corynespora, and other foliar diseases. The IR-4 Project completed 39 crop safety trials on 18 ornamental horticulture plant species or genera from 2015 through 2017. In these trials, sufficient injury was observed such that future development of both formulations tested was discontinued.
