Adjuvant requirements, compatibility notes, and mixing restrictions from the official label. Always confirm against the official label PDF before mixing.
| Guidance | Adjuvant | Rate |
|---|---|---|
| Required | ADIGOR Adjuvant For postemergence application, use an adjuvant (refer to Additive Use Requirements section). | – |
| Required | HiActivate® NIS For postemergence application use a minimum of 20 litres per 100 m² and add a non-ionic surfactant at 5 ml per litre of spray. | 5 ml per litre of spray |
| Recommended | ADIGOR Adjuvant Post emergence: Adjuvant use recommended. | – |
| Recommended | HiActivate® NIS The use of a non-ionic surfactant at 0.25 percent by volume (0.25 litre/100 litres spray volume) provides a maximum performance for all postemergence applications. Surfactant products must contain at least 50% nonionic surfactant. | 0.25% by volume (0.25 litre/100 litres spray volume) |
| Recommended | COC or MSO Petroleum crop oil concentrate or methylated seed oil at 1% by volume (1 litre/100 litres) can also enhance herbicide performance. Oil adjuvants must contain at least 15% surfactant emulsifiers and 80% high quality petroleum or methylated seed oil. | 1% by volume (1 litre/100 litres) |
