Crop × pest × application rate combinations from the official label. Rates converted to per-acre. PHI is the pre-harvest interval; REI is the restricted-entry interval. Always confirm against the official label PDF before applying.
| Crop | Target | Rate | PHI | REI |
|---|---|---|---|---|
| Blueberry | Preemergence and postemergence weed control - broadleaf weeds and grasses | 60.7–80.9 g/acre | – | 12 d |
| Grape | Postemergence weed control - broadleaf weeds and grasses less than 10 cm tall and before tillering of grasses | 60.7–80.9 g/acre | 75 d | 12 d |
| Grape | Preemergence weed control - broadleaf weeds and grasses | 60.7–80.9 g/acre | 75 d | 12 d |

| Guidance | Adjuvant | Rate |
|---|---|---|
| Required | NIS (non-ionic surfactant) 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. (Spot application) | 5 ml per litre of spray |
| Required | adjuvant (unspecified) For postemergence application, use an adjuvant (refer to Additive Use Requirements section). | – |
| Recommended | NIS (non-ionic surfactant) 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. |

| Compatible | COC (petroleum crop oil concentrate) 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) |
| Compatible | MSO (methylated seed oil) Petroleum crop oil concentrate or methylated seed oil at 1% by volume (1 litre/100 litres) can also enhance herbicide performance.
