- Applicators must now use at least a Very Coarse (VC) spray quality
- When using a boom sprayer, boom heights must be 0.5m or lower above the target canopy
- Downwind buffers now apply (typically less than 50m, subject to rate and product being applied) between application sites, downwind sensitive crops and environmentally sensitive aquatic areas
