Pulsor Fungicide (Thifluzamide 24% SC) - Ultimate Sheath Blight Control
Protect your paddy yield with Japanese technology. Pulsor is a premium systemic fungicide designed to eliminate Sheath Blight and boost crop health.
Manufactured by Insecticides (India) Limited in collaboration with Nissan Chemical Corporation (Japan), Pulsor contains Thifluzamide 24% SC. It is the gold standard for controlling Rhizoctonia solani in Rice, Potato, and Vegetable crops. Unlike older powders, this modern liquid formulation absorbs quickly and spreads evenly for superior protection.
Best For: Farmers seeking long-lasting protection against Sheath Blight and a visible "green" phytotonic effect on their crops.

How It Works: Mode of Action
Pulsor works by targeting the energy production centers (Mitochondria) of the fungus. Here is the simple breakdown:
- Energy Blockade: It inhibits the Succinate Dehydrogenase (SDH) enzyme. This cuts off the energy supply (ATP) to the fungus.
- Stops Growth: Without energy, the fungus cannot breathe or grow. Spore germination is halted immediately.
- Deep Penetration: It has translaminar action, meaning it moves from the top of the leaf to the bottom, killing hidden fungus in the lower canopy.
Result: The fungus dies of starvation and the crop recovers vigor.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Sheath Blight (Rhizoctonia solani) |
| Potato | Black Scurf (Seed Treatment) |
| Tomato | Early Blight (Alternaria solani) |
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 (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy (Rice) | 150 ml | 200 L | 0.75 ml | 28 - 30 |
| Tomato | 150 ml | 200 L | 0.75 ml | 7 |
| Potato (Seed) | Seed Treatment | - | 2.5 ml / 10kg | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply at the early stages of disease appearance (Maximum tillering to Booting stage for rice). Early application gives the best yield protection.
- Mixing: Pulsor is compatible with most insecticides (like Cartap or Chlorantraniliprole). Always perform a small jar test before mixing large quantities.
- Coverage: Ensure the spray reaches the lower leaf sheaths near the water line where Rhizoctonia fungus hides. Use 200 Litres of water per acre.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. What is the best time to spray Pulsor in Paddy?
The ideal time is the reproductive stage (booting). Spraying preventively or at the very first sign of sheath blight ensures the flag leaf remains healthy for grain filling.
2. Does Pulsor cure Black Scurf in Potatoes?
Yes, but it is most effective as a seed treatment. Treat the potato tubers with Pulsor before planting to prevent black scurf on the new harvest.
3. Is Pulsor rainfast?
Yes, Pulsor is absorbed into the leaf within 1 to 4 hours. If it rains after this period, the product will not wash off and will continue to work.
4. Can I mix Pulsor with insecticides?
Yes, it is generally compatible with common insecticides used for Stem Borer or Leaf Folder control, reducing your labor costs.
5. What is the price of Pulsor?
While MRP varies, the 150ml pack (sufficient for 1 acre) typically costs between ₹450 - ₹500 depending on your local dealer.
