Rogor Insecticide (Dimethoate 30% EC) by FMC - Broad Spectrum Pest Control
The original, trusted systemic insecticide for total protection against sucking pests and mites.
FMC Rogor is a powerful Dimethoate 30% EC formulation designed to protect your crops from the inside out. Known for its "dual-action" power, it hits pests on contact and travels within the plant to kill hidden insects. It is the go-to solution for cotton, maize, and potato farmers fighting Aphids, Jassids, and Mites.
Note: Following new government regulations (2023), this product is recommended for Field Crops (Cotton, Maize) and is restricted on raw salad vegetables.

How It Works: Mode of Action
Rogor attacks pests through a double mechanism, ensuring no pest survives whether it flies, crawls, or hides.
- Systemic Absorption: When sprayed, the liquid is absorbed by leaves and travels through the plant's sap (xylem). Sucking pests ingest the toxic sap and die.
- Contact & Stomach Action: Insects that are hit directly by the spray or walk over treated leaves absorb the poison through their skin (cuticle).
- Nerve Inhibition: Specifically, it blocks the enzyme Acetylcholinesterase (AChE), causing the insect's nervous system to fail, leading to paralysis and death.
Ideal for pests that hide on the underside of leaves or inside curled leaves.
Target Crops & Pests

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 | 150 - 200 L | 1.5 - 2 ml | 21 Days |
| Maize | 260 - 300 ml | 200 L | 1.5 ml | 30 Days |
| Mustard/Potato | 260 - 300 ml | 200 L | 1.5 ml | 21 Days |
*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 first sign of pest infestation (ETL). For Mustard, strictly apply before flowering or in the late evening to avoid killing honeybees.
- Mixing: Do not mix with alkaline substances like Bordeaux mixture or Lime Sulphur, as they will neutralize the poison. Use clean water with a pH of 5-7.
- Coverage: Ensure thorough coverage of the foliage. For stem borers in Maize, direct the nozzle spray into the leaf whorls.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. This product is a Yellow Triangle toxicant; handle with extreme care.
Frequently Asked Questions
1. Is Rogor safe for Tomato and Salad vegetables?
No. As per the 2023 government notification, Dimethoate (Rogor) should not be used on vegetables consumed raw (like salads, tomatoes, cucumbers) due to residue risks. Use it only for field crops like Cotton and Maize.
2. Does Rogor kill Mites?
Yes. Rogor has acaricidal properties, making it highly effective against Red Spider Mites, unlike many other sucking pest insecticides.
3. Is Rogor systemic or contact?
It is both. It kills insects on contact and also enters the plant system to provide long-lasting protection against pests that suck sap from the inside.
4. Can I mix Rogor with other chemicals?
Rogor is compatible with most insecticides and fungicides, but do not mix it with alkaline products (like Lime) as it destroys the chemical effectiveness.
5. What is the antidote for Rogor poisoning?
In case of accidental poisoning, the specific antidote is Atropine Sulphate and 2-PAM. Seek immediate medical attention and show the bottle/leaflet to the doctor.
