Why Choose This Product? Key Benefits
- 🌿Cotton focus: The Rallis Indian product page lists cotton whitefly.
- 🦟Contact and ingestion action: Rallis describes activity through contact and ingestion by the pest.
- 🧠Feeding disruption: Pyrifluquinazon affects insect coordination and feeding.
- 🧬Group 9B chemistry: Its mode of action differs from common neonicotinoid and pyrethroid groups.
- 📦Manufacturer pack choices: Rallis lists 100 g, 200 g and 500 g pack sizes. Check the selected pack before ordering.
Technical Specifications
| Parameter | Details |
|---|---|
| Brand Name | Clasto | Rallis India |
| Technical Name | Pyrifluquinazon 20% WG |
| IRAC MoA Code | 9B |
| Chemical Group | Pyridine azomethine derivative |
| Formulation | Water-dispersible granules (WG) |
| Toxicity Label | Agricultural pesticide. Follow the hazard warnings and protective equipment on the current pack. |
How It Works: Mode of Action
- Sensory signalling is disturbed: Pyrifluquinazon acts on chordotonal-organ TRPV channels involved in insect sensing and coordination.
- Feeding is reduced: Affected whiteflies lose normal feeding behaviour.
- The pest is controlled: Disrupted coordination and feeding lead to control of the labelled target.
Rotate modes of action according to the current label and local resistance-management advice; changing brands within Group 9B is not a different mode of action.

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 (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | See note* | 202.34 500 L/ha |
See note* | 30 |
Cotton–whitefly reference: water 500 L/ha and PHI 30 days. The published formulation dose is internally inconsistent with its active-ingredient entry, so the product dose is withheld until the current Clasto label resolves it.
An older Clasto catalogue says to treat cotton whitefly at pest occurrence or emergence. This timing reference does not resolve the dose or application route; confirm the current pack.
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*: confirm the dose and application route on the current Clasto pack. No per-litre, pump or spray-interval advice is supplied from retailer listings.
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.
