Rim Jhim Insecticide (Ethion 40% + Cypermethrin 5% EC)
The expert "One-Shot" solution for complex pest attacks: Controls Bollworms, Sucking Pests, and Mites simultaneously.
Rim Jhim, manufactured by Insecticides (India) Limited, is a powerful combination insecticide designed for Indian farmers. It solves the problem of "mixed pest attacks" by combining two potent active ingredients: Ethion (an expert mite and sucking pest killer) and Cypermethrin (a fast-acting bollworm killer). This pre-mix formulation saves you the hassle of tank-mixing different chemicals.
Best For: Cotton, Vegetables, Tea, and Pulses where pests like Bollworms and Whiteflies attack together.
Why Choose This Product? Key Benefits
- ⏱️Instant Knockdown Power: Cypermethrin provides a "shock effect," stopping pests from feeding immediately upon contact.
- ?️Dual-Action Protection: Works as both a Contact Poison (kills when pests touch it) and a Stomach Poison (kills when pests eat treated leaves).
- ⏳Stops Mite Flare-ups: Unlike ordinary pyrethroids that can increase mite populations, the Ethion in Rim Jhim actively kills mites (Acaricidal action).
- ?️Rainfastness: The EC formulation absorbs quickly into the leaf. It generally requires a rain-free period of just 3 to 4 hours to be effective.
- ?Synergistic Formula: Ethion helps protect Cypermethrin from pest resistance mechanisms, making the combination more effective than using either chemical alone.

How It Works: Mode of Action
Rim Jhim attacks the insect's nervous system from two different angles, making it very difficult for pests to survive.
- Nerve Overload (Cypermethrin): It targets the sodium channels in the nerve axons, keeping them open. This causes continuous nerve firing, leading to tremors and paralysis.
- Enzyme Blockage (Ethion): It inhibits the enzyme acetylcholinesterase (AChE) at the synaptic cleft. This prevents the insect from "switching off" nerve signals.
- Resistance Breaking: Ethion occupies the detoxification enzymes in the insect's body, effectively "shielding" the Cypermethrin so it can deliver a lethal blow to resistant pests.
The result is a rapid cessation of feeding, followed by paralysis and death of the pest.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|

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 | 400 - 500 ml | 200 L | 2.0 - 2.5 ml | 15 |
| Chilli & Veg | 400 - 600 ml | 200 - 300 L | 2.0 - 2.5 ml | 10 - 15 |
| Pulses | 400 - 500 ml | 200 L | 2.0 - 2.5 ml | 15 - 20 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply when pest population reaches the Economic Threshold Level (ETL)—for example, when you see 5-10% damage to fruiting bodies or 5-10 mites per leaf.
- Mixing: Compatible with most fungicides (like Mancozeb). Do NOT mix with alkaline products like Bordeaux mixture or Lime Sulphur, as this destroys the medicine.
- Coverage: Use at least 200 Liters of water per acre for Cotton and Vegetables. Good coverage of the underside of leaves is essential for killing mites and hiding pests.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during peak bee foraging hours (mid-day).
Frequently Asked Questions
1. Why use Rim Jhim instead of plain Cypermethrin?
Plain Cypermethrin often kills beneficial insects, leading to a sudden increase in Mites. Rim Jhim contains Ethion, which controls mites while Cypermethrin kills the bollworms, offering safer, complete protection.
2. Does it control Whiteflies?
Yes. The combination is effective against sucking pests like Whiteflies and Jassids, in addition to controlling chewing pests like Bollworms.
3. What is the antidote for accidental poisoning?
The specific antidotes are Atropine Sulphate and 2-PAM. In case of ingestion or severe exposure, seek immediate medical attention and show the bottle/leaflet to the doctor.
4. Can I use this on export crops?
Use caution. Ethion has strict residue limits in the European Union (EU). For export-oriented crops, consult your agronomy advisor regarding current Maximum Residue Limits (MRLs).
5. Is it rainfast?
Yes, Rim Jhim is an EC formulation that penetrates leaves quickly. However, for best results, avoid spraying if rain is expected within 3-4 hours.
