| 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. | lowest labeled rate of nonionic-type surfactants that contain at least 80% active ingredients |
| Required | NIS Use a nonionic surfactant (NIS) with post-emergence applications. | – |
| Required | NIS Use a nonionic surfactant (NIS) if labeled weeds are emerged. | – |
| Required | NIS or COC A nonionic surfactant or crop oil concentrate should be used with post harvest applications. | – |
| Recommended | adjuvant Use of Sandea WG Herbicide without an adjuvant when weeds are present may result in reduced efficacy. | – |
| Compatible | COC For tank-mixes with Sandea WG Herbicide, crop oil concentrates may be used instead of nonionic surfactants. | – |
| Do not mix | adjuvant during asparagus harvest Use of an adjuvant with any applications made before or during harvest may increase the potential for crop injury and are not recommended. | – |
