Ruler 0.3 Gr Insecticide (Fipronil 0.3% GR) - Total Termite & Borer Control
Expert solution for Rice, Wheat, and Sugarcane with dual-action power.
Ruler 0.3 Gr by Krishi Rasayan is a high-performance granular insecticide designed to tackle tough soil insects and stem borers. Powered by Fipronil, it doesn't just kill pests; it provides a "Phytotonic Effect" that boosts root development and makes your crop greener.
Best For: Farmers seeking long-lasting protection (up to 40 days) against Stem Borers, Brown Plant Hoppers (BPH), and Termites without the hassle of spraying.
Why Choose Ruler 0.3 Gr? Key Benefits
-
⏱️
Dual-Action Power: Works through both contact (touch) and systemic (root absorption) action, ensuring pests die even if they are hiding inside the stem.
-
🛡️
Long-Lasting Protection: The slow-release granular technology stays active in the soil for 30 to 40 days, covering the most critical crop growth stages.
-
⏳
Plant Growth Enhancer (PGE): Experience the "Greening Effect." Ruler increases chlorophyll content, results in more productive tillers in rice, and improves cane girth in sugarcane.
-
🌧️
Easy Application: No mixing tanks required. Simply broadcast the granules by hand or spreader directly into the field.
-
🌿
Targeted Root Zone Defense: Designed to settle on the soil surface, creating a chemical barrier exactly where termites and root borers attack.

How It Works: Mode of Action
Ruler 0.3 Gr attacks the insect's central nervous system, specifically targeting the GABA receptors.
- Nerve Blockade: Fipronil blocks the entry of chloride ions into nerve cells, removing the "brakes" on the insect's nervous system.
- Systemic Transport: Once applied to the soil, plant roots absorb the active ingredient and transport it up to the stem and leaves.
- Rapid Mortality: Any insect feeding on the plant or touching the treated soil suffers from hyperexcitability, paralysis, and death.
Note: This unique mode of action makes it an excellent choice for rotating with other insecticides to prevent resistance.
Target Crops & Pests
| Crop | Target Pest(s) |

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Ensure adequate soil moisture for activation.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (kg / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice | 6.6 kg - 10 kg | Standing water (2-3cm) | N/A (Granules) | 32 Days |
| Sugarcane | 10 kg - 13.3 kg | Soil Application | N/A (Granules) | 270 Days |
| Wheat | 8 kg | Soil Application | N/A (Granules) | 91 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing (Rice): Apply 15-20 days after transplanting (DAT) for early protection, or immediately when pests are seen.
- Mixing: For Wheat/Sugarcane, mix granules with dry sand (1:1 ratio) to ensure you spread it evenly across the whole acre.
- Coverage (Rice): Maintain 2-3 cm of standing water in the field for 2-3 days after application. Do not drain the water, as this allows the medicine to soak into the soil.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not eat or smoke while handling granules.
Frequently Asked Questions
1. Does Ruler 0.3 Gr control termites in wheat?
Yes, it is highly effective against termites. Apply it at 8 kg per acre mixed with sand before sowing or with the first irrigation.
2. Is this product safe for fish farming (pisciculture)?
No. Fipronil is highly toxic to fish. Do not use Ruler 0.3 Gr in fields used for aquaculture or rice-fish farming.
3. Can I use Ruler in dry soil?
No. Granules need moisture to release the active ingredient. Ensure there is standing water (Rice) or moist soil (Wheat/Cane) for it to work.
4. How does it improve crop yield?
Ruler has a phytotonic effect that stimulates root growth and photosynthesis, leading to greener leaves and more productive tillers.
5. What is the shelf life of the product?
When stored in a cool, dry place in original packaging, it is generally stable for 2 years from the date of manufacture.
