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.

Dosage & Application Guide
The numerical entries below are formulation-level CIBRC reference data through 30 September 2025, not confirmation of the current branded pack directions. Match each crop, target, route, water volume and harvest interval to the current Indian label before use.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Mango | See note* | See note* | 2 | 27 |
| Rice | See note* | See note* | See note* | 40 |
| Grapes | 202.34–404.69 500–1000 ml/ha |
202.34 500 L/ha |
See note* | See note* |
Mango–powdery mildew: the reference explicitly gives 200 ml/100 L water, equivalent to 2 ml/L; water is as required for tree size and application equipment. There is no fixed hectare amount in that row.
Rice–sheath blight remains a verified Rallis use. The formulation reference repeats tree-size water wording in the rice row, so that generic dose and water wording remain held pending the current Contaf Plus leaflet. The separately stated reference PHI is 40 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. The mango concentration must not be applied automatically to this grape area-rate programme.
Separate undated Contaf Plus catalogue: occurrence/emergence timing is stated for the three listed crops. Rice sheath blight explicitly has 200 ml/100 L water (2 ml/L) and PHI 40 days, without water-per-area or route. This is a historical branded concentration reference, not a repair of the generic rice row or a current-label claim. Grapes powdery mildew has 400 ml/acre and PHI 60 days, with water and route unstated; do not combine this with the generic water or shorter PHI.
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*: no hectare dose or fixed water volume is supplied for mango. The generic rice dose and water wording require clarification; the separate catalogue concentration still needs current-pack confirmation. No independent per-litre grape dose has been calculated. Application route, stage, interval, maximum applications and re-entry require the current Indian Contaf Plus 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.
Frequently Asked Questions
Is Contaf Plus the same as Contaf 5 EC?No. Contaf Plus is hexaconazole 5% SC. Contaf is a separate 5% EC formulation.
Which crops are verified for Contaf Plus?Rallis lists mango powdery mildew, rice sheath blight and grape powdery mildew. Rice is retained even though some dose details need clarification.
Does 2 ml/L apply to every crop?No. The mango formulation reference and a separate historical rice catalogue each give 2 ml/L, but these do not establish a universal programme. Grapes has an area-rate reference; confirm each current crop programme.
What are the reference harvest intervals?Mango 27 days and rice 40 days are reference values. Grape PHI is unresolved: the generic table says 14 days while the historical branded catalogue says 60. Obtain the current pack’s grape interval before use.
Is 400 ml/acre a universal dose?No. That historical catalogue rate is for grapes only, without a stated water volume or route. Mango and rice have distinct concentration references; do not transfer rates between crops.
