| Guidance | Adjuvant | Rate |
|---|---|---|
| Required | AgSurf or Agral 90 Adjuvant: Non-ionic surfactant (AgSurf or Agral 90) at 0.125% v/v | 0.125% v/v |
| Required | non-ionic surfactant Adjuvant: Apply with a non-ionic surfactant, e.g., AgSurf or Agral 90, at 0.125% v/v | 0.125% v/v |
| Required | non-ionic surfactant Adjuvant: Apply with a non-ionic surfactant, AgSurf or Agral 90 at 0.125% v/v | 0.125% v/v |
| Recommended | AgSurf or Agral 90 Adjuvant: Non-ionic surfactant (AgSurf or Agral 90) at 0.125% v/v (optional) | 0.125% v/v |
| Recommended | AgSurf or Agral 90 Adjuvant: Non-ionic surfactant (AgSurf or Agral 90) at 0.125% v/v (optional, do not apply prior to tassel emergence) | 0.125% v/v |
| Recommended | non-ionic surfactant Under high disease pressure, it is recommended to use a non-ionic surfactant with FBN Prothio 480 SC (do not apply a non-ionic surfactant prior to tassel emergence as crop injury may occur).

| Compatible | non-ionic surfactant FBN Prothio 480 SC may be applied with a non-ionic surfactant, e.g., AgSurf or Agral 90, at 0.125% v/v. | 0.125% v/v |
| Do not mix | non-ionic surfactant on corn prior to tassel emergence Do not apply a non-ionic surfactant prior to tassel emergence as crop injury may occur. | – |
