How It Works: Mode of Action
- The active enters plant tissue: Rallis describes systemic activity of hexaconazole in this product.
- Sterol synthesis is inhibited: Hexaconazole blocks fungal sterol 14α-demethylase, a key step in forming membrane sterols.
- Fungal growth is checked: Disrupted membrane formation helps control the listed diseases.
Other FRAC Group 3 fungicides share this mode of action. Follow a label-compliant rotation and do not treat a brand change alone as resistance management.

Apple–scab: explicit reference concentration 50 ml/100 L, equivalent to 0.5 ml/L; water as required, PHI 30 days. Mango–powdery mildew and soybean–rust: each 100 ml/100 L, equivalent to 1 ml/L; water as required and PHI 30 days. No fixed hectare dose is given for these concentration-based rows.
Rice–blast and sheath blight: 1,000 ml/ha in 500 L/ha, PHI 40 days. Groundnut–tikka leaf spot: 1,500 ml/ha in 500 L/ha, PHI 30 days. Grapes–powdery mildew: 500–1,000 ml/ha in 500 L/ha, generic reference PHI 14 days, which conflicts with the historical branded catalogue’s 60 days. The current grape PHI is held pending the current pack, not selected from either value.
Tea–blister blight: 200 ml/ha with PHI 7 days. The reference pairs 70–90 L/ha with power sprayers and 175–200 L/ha with knapsack sprayers; these are alternatives, not additive volumes.
Separate undated Contaf catalogue: occurrence/emergence timing is stated for all seven listed crop–disease programmes. Its grape powdery-mildew entry gives 400 ml/acre and PHI 60 days, with water volume and route unstated. This historical branded reference is not combined with generic hectare data. The grape PHI conflict must be resolved from the current Indian pack before use.
Per-acre amounts are approximate conversions of the stated hectare rates using 1 acre = 0.40468564224 ha. The original hectare figures are retained. No per-litre or tank rate has been calculated from an area rate.
See note*: concentration-based apple, mango and soybean rows have no fixed hectare dose or water volume. The other rows have no independent per-litre dose. Apart from the stated tea sprayer choices, crop-specific route, stage, interval, maximum applications and re-entry require the current Contaf 5 EC label.
How to Apply: Best Practices
- Confirm the programme: Check the current label for the exact crop, target, method and timing before preparing any treatment.
- Measure and calibrate: Measure the formulation accurately and use the label water volume with calibrated equipment. Do not substitute a tank rate from another formulation.
- Plan harvest and re-entry: Observe the crop-specific pre-harvest interval and the pack’s re-entry instructions. A missing value does not mean immediate harvest or entry.
