Rogorin Insecticide (Dimethoate 30% EC) by IIL
The trusted systemic and contact solution for sucking pests and borers.
Rogorin is a broad-spectrum organophosphate insecticide manufactured by Insecticides (India) Ltd. It is designed to control tough sucking pests like aphids, jassids, and whiteflies, as well as internal feeders like stem borers.
Why farmers love it: Unlike sprays that only kill on contact, Rogorin is absorbed by the plant. This "Systemic Action" means it kills hidden pests feeding on the sap, even if they are hiding under leaves or inside the stem. It offers a powerful "rescue" solution at an affordable price point.

How It Works: Mode of Action
Rogorin attacks the nervous system of the insect. It is an Acetylcholinesterase (AChE) inhibitor.
- Absorption: When sprayed, the chemical is absorbed by the plant's leaves and roots.
- Translocation: It travels up through the plant's system (xylem) to the tips and new leaves.
- Elimination: When sucking pests (like aphids) or borers eat the plant sap or tissue, they ingest the poison. This paralyzes their nervous system, leading to rapid death.
Note: It also works on contact if the spray lands directly on the insect.

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) |
|---|---|---|---|---|
| Cotton | 250 - 300 ml | 200 - 300 L | 1.5 ml | 14 - 21 |
| Vegetables (Okra/Brinjal) | 200 - 264 ml | 200 L | 1.0 - 1.5 ml | 7 - 10 |
| Maize / Mustard | 264 ml | 200 L | 1.5 ml | 14+ |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray at the first sign of pests (e.g., crinkling leaves or honeydew). Avoid spraying during mid-day to protect honeybees.
- Mixing: Rogorin is acidic/neutral. NEVER mix with alkaline products like Bordeaux Mixture or Lime Sulfur, as they destroy the chemical instantly.
- Coverage: Use a hollow cone nozzle for fine mist. Ensure good coverage, but the systemic action will help reach missed spots.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not re-enter the field for 48 hours.
Frequently Asked Questions
1. Can I mix Rogorin with fungicides?
Yes, it is compatible with Mancozeb. However, strictly avoid mixing with Bordeaux mixture or Lime Sulfur as high pH makes Rogorin ineffective.
2. Does Rogorin kill stem borers?
Yes. Because it is systemic, it enters the plant tissue and kills borers hiding inside the stem or fruit.
3. Is it safe for Honeybees?
No, it is toxic to bees. Do not spray during active flowering times or when bees are foraging. Spray in the late evening.
4. What is the waiting period (PHI) for vegetables?
For vegetables like Okra and Brinjal, you must wait at least 7 to 10 days after spraying before harvesting to ensure the residue is safe.
5. What is the antidote for accidental poisoning?
In case of poisoning, seek immediate medical help. The specific antidote is Atropine Sulphate, administered by a doctor.
