How It Works: Mode of Action
Azoxystrobin interferes with energy production in susceptible fungi. Tebuconazole inhibits ergosterol synthesis, disrupting normal fungal cell membranes.
- Energy effect: Azoxystrobin interrupts fungal mitochondrial respiration.
- Membrane effect: Tebuconazole blocks a step in ergosterol formation.
- Disease suppression: These effects disrupt normal fungal growth and development.
Use the current label and local resistance-management advice. A second active ingredient or a change of brand does not guarantee that resistance will be prevented.

Dosage & Application Guide
These are manufacturer product-page references, not a substitute for the supplied label. Keep product amount, water and harvest interval paired with the same crop.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose / Litre | PHI (Days) |
|---|---|---|---|---|
| Group 1* | 300 | Confirm* | Confirm* | Confirm* |
The manufacturer gives 300 ml/acre for the listed uses but does not provide crop-specific water, dilution or harvest intervals. Confirm all three before application.
Group 1*: Grapes, Onion, Chilli, Paddy, Apple, Wheat, Potato. *A field marked “Confirm” is not established for use here. Obtain the missing or corrected instruction before treatment; an absent PHI does not mean zero days.
No spray-tank quantity, rainfast period, re-entry interval, repeat interval or maximum application count is inferred. Check the label for these instructions.
