⏱️
Instant Knockdown (Paralysis): Powered by Dinotefuran, it immediately paralyzes pests upon contact, stopping damage instantly.
-
🛡️
Double Power Protection: Contains two different chemical actions, making it highly effective against pests that are resistant to older medicines like Imidacloprid.

How It Works: Mode of Action
Twin Gold uses a "5 Gear Technology" to completely halt the pest lifecycle:
- Immediate Paralysis (Gear 1): Dinotefuran hits the pest's nervous system, causing instant tremors and paralysis.
- Permanent Starvation (Gear 2 & 3): Pymetrozine causes "Mouth Lock." The pest withdraws its feeding tube and permanently stops eating, leading to starvation.
- Population Control (Gear 4 & 5): The pest loses coordination, falls off the plant ("Clean Field"), and any survivors become unable to lay eggs.
This combination makes it a Systemic, Translaminar, and Contact insecticide.

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) |
|---|---|---|---|---|
| Paddy (Rice) | 133.2 g | 200 Liters | ~0.66 g | 24 Days |
| Cotton | 133.2 g | 200 Liters | ~0.66 g | 21-24 Days |
| Vegetables | 133.2 g | 200 Liters | ~0.66 g | 5-7 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Rice exporters must strictly follow the 24-day rule.
How to Apply: Best Practices
- Timing: Spray immediately when you see 5-10 hoppers per hill (Economic Threshold Level). Do not wait for severe "Hopper Burn."
- Mixing: Dissolve the granules in a separate bucket first. Do not mix with highly alkaline products like Bordeaux mixture.
- Coverage: Direct the spray nozzle towards the base of the paddy plant where BPH hides. Use hollow cone nozzles for better mist.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during active flowering to protect bees.
Frequently Asked Questions
1. What is the difference between Twin Gold, Osheen, and Chess?
Osheen contains only Dinotefuran; Chess contains only Pymetrozine. Twin Gold combines both, giving you the fast action of Dinotefuran and the long-lasting control of Pymetrozine in one spray.
2. Does Twin Gold kill eggs?
While it primarily targets nymphs and adults, Pymetrozine significantly reduces the female's ability to lay eggs, preventing the next generation from hatching.
3. Is this product safe for Honey Bees?
No. It is toxic to bees. Do not spray during peak flowering times or when bees are actively foraging. Evening spraying is recommended.
4. What is the pack size available?
It is commonly available in 133.2g packs (which is the exact dose for 1 acre) and larger bulk sizes like 1.33kg.
5. Can I mix it with fungicides?
Yes, it is generally compatible with common rice fungicides like Hexaconazole or Tricyclazole, but always perform a small jar test first.
