Supremo SP Insecticide: The Ultimate Solution for Rice Stem Borer & Leaf Folder
Unlock higher paddy yields with the power of Thiocyclam Hydrogen Oxalate.
Supremo SP (by Insecticides India Ltd.) is a specialized, broad-spectrum insecticide designed to protect your rice crop from stubborn pests. Unlike older chemicals, Supremo uses a unique technology derived from marine biology to tackle pests that have developed resistance to other products.
Best For: Farmers facing heavy infestations of Stem Borer ("Dead Heart") and Leaf Folder in Rice who need a fast-acting, systemic solution.
Why Choose This Product? Key Benefits
- ⏱️Stops Damage Instantly: Pests stop feeding immediately after contact or ingestion, preventing further crop loss within minutes.
- ?️Dual Action Protection: Works through Contact (spraying the insect) and Systemic action (absorbed by the plant to kill hidden borers).
- ⏳Resistance Breaker: Its unique chemistry (Nereistoxin analogue) kills pests that have survived other common sprays like pyrethroids.
- ?️Highly Soluble: The SP (Soluble Powder) formulation dissolves completely in water, ensuring easy spreading and rapid absorption by the leaves.
- ?Yield Booster: Field trials show significantly higher grain yields due to effective "Dead Heart" and "White Ear" control.

How It Works: Mode of Action
Supremo SP works by attacking the Central Nervous System of the insect. It is modeled after a natural toxin found in marine worms.
- Uptake: Upon spraying, the chemical is absorbed by the plant (Translaminar/Systemic) and covers the surface.
- Blockade: When the pest eats the treated plant, the chemical blocks the "nicotinic acetylcholine receptors" in their nerves.
- Paralysis: This stops nerve signals. The insect becomes paralyzed, stops feeding instantly, and dies within 24–72 hours.
*Note: Because it works differently than other poisons, it kills pests that are resistant to common sprays.

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) |
|---|---|---|---|---|
| Rice (Paddy) | 400 g | 200 Litres | 2 g | 30 |
| - | - | - | - | - |
| - | - | - | - | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply when you see 1 egg mass/m² or 5% "Dead Hearts" in the field. Early application prevents larvae from entering the stem.
- Mixing: Dissolve Supremo SP in the tank first (WALES method). Do NOT mix with alkaline products like Bordeaux mixture or Lime Sulfur, as they destroy the medicine.
- Coverage: Use at least 200 Litres of water per acre. Good coverage is essential for the systemic action to work.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not drain field water for 7 days to protect fish.
Frequently Asked Questions
1. Does Supremo SP control Brown Plant Hopper (BPH)?
While it affects sucking pests, it is primarily labeled for Stem Borer and Leaf Folder. For BPH specifically, other specialized products like Pymetrozine might be better suited, though Supremo provides some suppression.
2. Can I use Supremo on Basmati Rice for export?
The European Union has strict residue limits (MRLs) for Thiocyclam. If exporting to the EU, avoid using this product. For domestic use or non-EU export, it is safe if the 30-day PHI is followed.
3. Is it rainfast?
Yes, being a Soluble Powder, it enters the plant system quickly. However, it is best to spray when there is no rain forecast for at least 2-4 hours.
4. What is the price of Supremo SP?
The approximate cost is ₹650 - ₹800 per acre, making it a cost-effective mid-range solution compared to expensive diamides.
5. Is it safe for bees?
No. Thiocyclam is toxic to bees. Avoid spraying during active flowering times or if bees are foraging nearby.
