Syngenta Chess® Insecticide (Pymetrozine 50% WG)
The Expert Solution for Brown Plant Hopper (BPH) Control in Rice
Are you seeing "Hopper Burn" in your paddy fields? Syngenta Chess® is a specialized systemic insecticide designed to stop sucking pests immediately. Unlike ordinary poisons, it works by "starving" the pest, ensuring they stop damaging your crop within minutes of application.
Best for: Farmers looking for long-lasting protection against BPH, White Backed Plant Hoppers, and Aphids while keeping beneficial insects like spiders safe.
Why Choose This Product? Key Benefits
- ⏱️Immediate Feeding Stop: Pests stop sucking sap within 1 hour of spraying (prevents "Hopper Burn").
- ?️Long-Lasting Protection: One spray protects your crop for 10 to 14 days, reducing the need for frequent rounds.
- ⏳Prevents Viral Diseases: By stopping the pests quickly, it halts the spread of Grassy Stunt and Ragged Stunt viruses.
- ?️Excellent Rainfastness: The medicine is absorbed quickly; rain 2 hours after spraying will not wash it away.
- ?Eco-Friendly (IPM Safe): Safe for spiders and friendly insects that eat pests, preventing pest resurgence later.

How It Works: Mode of Action
Chess® works differently from older poisons. It targets the "Chordotonal Organs"—the nervous system that controls the insect's balance and feeding muscles.
- Immediate "Mouth Lock": Upon contact or ingestion, the insect's feeding tube (stylet) becomes paralyzed.
- Starvation Effect: The pest can no longer suck plant sap. It may remain on the plant appearing alive, but it is harmless.
- Ecological Death: Within 2-5 days, the pest dies of starvation. This unique method ensures pests don't develop resistance easily.
Note: Do not panic if you see insects moving after spraying. As long as they are not feeding, your crop is safe.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Paddy) | Brown Plant Hopper (BPH), Green Leaf Hopper (GLH), White Backed Plant Hopper (WBPH) |
| Mango | Mango Hoppers |
| Vegetables & Cotton | Aphids and Whiteflies |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. For BPH, water volume is the key to success.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Paddy) | 120 grams | 200 Litres | 0.6 g | 20 Days |
| Vegetables | 100 - 120 grams | 150 - 200 Litres | 0.5 - 0.75 g | 14 Days |
| Mango | Depends on Tree Size | - | 0.6 g | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray at the "Economic Threshold Level" (ETL), which is usually when you see 5-10 hoppers per hill. Do not wait for severe damage.
- Mixing: Dissolve the granules in a small amount of water first to create a solution, then add to the main tank. Ensure you use at least 200 Litres of water per acre for Rice to penetrate the canopy.
- Coverage: For BPH, direct the nozzle towards the base of the plant (the culm) where the hoppers reside, not just the top leaves.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not use near fish ponds.
Frequently Asked Questions
1. Does Chess kill the pests instantly?
No, it does not "knock down" pests instantly like some poisons. It stops them from feeding immediately, so damage stops. The pests will die of starvation after 2-4 days.
2. Is Chess compatible with other products?
Yes, Chess® is generally compatible with common fungicides (like Amistar Top) and insecticides. However, always perform a physical mix test before full application.
3. Can I use it on Basmati Rice for export?
Yes, provided you strictly follow the dosage and the Pre-Harvest Interval (PHI) of 20 days to meet residue limits (MRLs).
4. What is the difference between Chess and Imidacloprid (Confidor)?
Imidacloprid is an older chemical that many pests are now resistant to. Chess works on a different system (Chordotonal organs), making it highly effective even against resistant BPH.
5. Is it safe for fish culture in paddy fields?
No. Pymetrozine is toxic to aquatic life. Do not use it if you are practicing rice-fish culture or near water bodies.
