Mode of Action & Resistance Stewardship
Hexaconazole inhibits sterol biosynthesis through the DMI target site. FRAC generally recognises cross-resistance within Group 3, so another Group 3 fungicide should not automatically be treated as a different-mode-of-action rotation partner. Follow the label and a locally appropriate resistance-management programme.
Application & Safety Practices
- Read the current pack label and leaflet before measuring or spraying.
- Use only on the approved crop and disease at the stated dose, water volume and PHI.
- Wear the PPE specified on the label and use calibrated, leak-free equipment.
- Do not assume tank-mix compatibility; combine products only where both labels permit it and qualified advice confirms it.
- Follow all label directions for first aid, re-entry, storage, transport, environmental protection and disposal.
