| Guidance | Adjuvant | Rate |
|---|---|---|
| Required | NIS Unless otherwise stated, use a nonionic surfactant (NIS) in spray solution for post emergent applications or for preemergence applications where susceptible weeds are present prior to crop emergence. Use ONLY the lowest labeled rate of nonionic-type surfactants that contain at least 80% active ingredients. | lowest labeled rate of nonionic-type surfactants that contain at least 80% active ingredients |
