Clasto Insecticide (Pyrifluquinazon 20% WG): The Ultimate Sucking Pest Solution
Stop Whiteflies and Aphids instantly with the power of novel Japanese chemistry.
Clasto Insecticide, brought to you by Rallis India (a Tata Enterprise), is a breakthrough solution designed to fight stubborn sucking pests. Powered by Pyrifluquinazon 20% WG, it doesn't just kill pests—it immediately stops them from feeding. This unique action protects your high-value crops like Cotton and Chilli from viral diseases like Leaf Curl Virus, ensuring higher yields and better quality.
Best For: Breaking resistance in Whiteflies, Aphids, and Jassids when older chemicals fail.
Why Choose Clasto Insecticide? Key Benefits
- ⏱️Stops Feeding Instantly: Pests stop damaging the crop immediately upon contact, preventing "Hopper Burn" and yield loss.
- ?️Blocks Virus Spread: By halting feeding rapidly, Clasto prevents Whiteflies from transmitting deadly viruses like CLCuV and ChiLCV.
- ⏳Long-Lasting Protection: Enjoy peace of mind with extended residual control that lasts for 14 to 21 days after spraying.
- ?️Translaminar Action: The medicine penetrates the leaf surface to kill pests hiding on the underside, where normal sprays can't reach.
- ?Safe for Friendly Insects: Ideally suited for IPM, it harms pests but is safer for beneficial insects like predatory mites and wasps.

How It Works: Mode of Action (IBR)
Clasto works differently than older poisons. It acts as an Insect Behavior Regulator (IBR).
[Image of insect nervous system diagram]- The "Stop" Effect: Upon contact, the chemical affects the pest's "Chordotonal Organs" (sensory system). The insect immediately withdraws its mouthpart and stops feeding.
- The "Drop" Effect: The pest loses coordination, becomes dizzy, and cannot hold onto the leaf, often falling off the plant.
- The "Starve" Effect: Because they cannot eat, the pests die from starvation and dehydration within 1 to 3 days.
Note: You might still see pests on the leaf for a day, but they are harmless because they have stopped feeding.

Clasto Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 200 g | 200 L | 1.0 g | 21 Days |
| Chilli | 200 g | 200 L | 1.0 g | 7-14 Days* |
| Vegetables | 200 g | 200 L | 1.0 g | 7-14 Days* |
*PHI = Pre-Harvest Interval: Check local label for specific export vegetable PHI.
How to Apply: Best Practices
- Timing: Apply at the first sign of pest activity (ETL) or when you see "leaf curling." Early application prevents viral spread.
- Mixing: Premix the granules in a bucket of water before adding to the main tank. It mixes easily and creates a stable suspension.
- Coverage: Use Hollow Cone Nozzles and ensure 200 Liters of water per acre to cover the undersides of leaves where Whiteflies hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during peak bee foraging hours.
