General Instructions (If using on a new crop)
- Trial a small test area (~1 m²) before full application.
- Coverage is critical → always spray to adequate wetting.
Irrigation / Fertigation Use.
- Add to B tank only, Max concentration 1.5 L per 100 L stock solution.
Practical Takeaways.
- Works best with consistent repeat applications.
- Coverage + frequency matter more than pushing high rates.
