DuPont Crop Objectives for penthiopyrad:

  3. Penthiopyrad spectrum of control • Key biological fit for the control of the following diseases/pathogens across all crops: • Foliar pathogens: • Powdery mildew, Rhizoctonia, Sclerotinia, Sclerotium rolfsii, rust. Septoria, Ascochyta, Alernaria, Monilinia, Botrytis, Cylindrocladium, Cercospora, Venturia inequalis, plus many others. • Key soilborne pathogens: • Sclerotinia, Rhizoctonia, Sclerotium rolfsii • Penthiopyrad does not control: • Oomycetes- downy mildew and Phytophthora

  4. Penthiopyrad is effective at low use rates • The application rate typically will vary from 100 to 400 g ai/ha. • The specific use rate will depend on the target crop and disease, as well as the method of application, disease pressure, presence of other fungicide mix partners, and other factors.

  5. Penthiopyrad Crop Dashboard Summary Key crop group and subgroups to be registered: 1-C, 3-07, 4, 6C, 8, 9, 10, 11, 12, 13-07F, 13-07G, 14, 15, 20 Possible IR-4 Crop group and subgroup expansion opportunities: 1A, 1B, 1D, 5A 5B, 6A, 6B, 13-07A-E, 19A, 19B
