Ortain Super Insecticide (Acephate 50% + Fipronil 5% WDG)
The Ultimate Dual-Action Solution for Hard-to-Kill Pests in Rice and Cotton.
Coromandel Ortain Super is a premium broad-spectrum insecticide designed to break pest resistance. It combines two powerful active ingredients—Acephate and Fipronil—in a modern Water Dispersible Granule (WDG) formulation.
Best For: Farmers dealing with mixed infestations of chewing pests (like borers) and sucking pests (like hoppers) simultaneously. It not only kills pests but also promotes better plant health.
Why Choose This Product? Key Benefits
-
⏱️
Double Action Power: Combines Systemic action (absorbs into the plant) and Contact action (kills on touch) to eliminate hidden pests and surface feeders.
-
🛡️
Resistance Breaker: Ideally engineered to control pests that have stopped responding to single-chemical sprays.

How It Works: Mode of Action
Ortain Super creates a "Neurotoxic Crossfire" that attacks the insect nervous system in two different ways, making it very difficult for pests to survive.
- Systemic Attack (Acephate): Absorbed by the plant and moves through the sap. It targets the Acetylcholinesterase enzyme, causing paralysis in insects that feed on the sap or stem.
- Contact Attack (Fipronil): Stays on the leaf surface. It blocks GABA-gated chloride channels, causing hyperexcitation and death when insects touch the treated area.
- Synergy: The combination ensures that if a pest is resistant to one chemical, the other one will likely eliminate it.
Result: Rapid knockdown of pests and extended residual control.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Stem Borer, Leaf Folder, Brown Plant Hopper (BPH), Green Leaf Hopper (GLH) |
| Cotton | Bollworm Complex, Aphids, Jassids, Thrips, Whiteflies |
| Safflower | Aphids |
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/g per Acre) | Water (L / Acre) | Dose (ml/g per Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy (Rice) | 266 - 400 g | 150 - 200 L | 2.0 g | 27 Days |
| Cotton (Sucking Pests) | 156 g | 150 - 200 L | 1.0 g | - |
| Cotton (Bollworms) | 312 g | 150 - 200 L | 1.5 - 2.0 g | - |
*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 Economic Threshold Level (ETL). For rice, this is typically when you see 5% dead hearts or 2 damaged leaves per hill.
- Mixing: Do NOT mix with alkaline substances like Bordeaux mixture or Lime Sulfur, as this reduces effectiveness. Use clean water.
- Coverage: Ensure thorough coverage of the foliage. Use 150-200 liters of water per acre for manual spraying.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during active bee foraging hours.
Frequently Asked Questions
1. What is the main advantage of Ortain Super?
It provides a "one-shot" solution for both stem borers (internal feeders) and sucking pests, saving you the cost and labor of mixing multiple products.
2. Is Ortain Super systemic?
Yes, the Acephate component is highly systemic, moving within the plant to kill hidden pests. The Fipronil component provides strong contact action on the surface.
3. Can I mix fungicides with Ortain Super?
Yes, it is generally compatible with common rice fungicides like Hexaconazole and Tricyclazole. However, avoid alkaline mixes.
4. How long do I need to wait before harvesting rice?
You must wait at least 27 days after the last spray before harvesting to ensuring the grain is safe (PHI = 27 Days).
5. Is this product safe for fish?
No, Fipronil is toxic to fish. Do not drain paddy water into natural water bodies immediately after application.
