Fosmite Insecticide (Ethion 50% EC): The Expert Solution for Mites & Borers
A dual-action powerhouse that protects Tea, Cotton, and Chilies from tough mites and chewing insects.
Fosmite (Ethion 50% EC) is a time-tested insecticide and acaricide trusted by Indian farmers for decades. Unlike standard pesticides that only target one type of pest, Fosmite delivers broad-spectrum control, effectively eliminating both mites (acarines) and insects in a single spray.
Best For: Managing complex infestations of Red Spider Mites, Thrips, and Bollworms in high-value crops. Its specialized oil-based formulation penetrates leaf webs and waxy layers, ensuring no pest can hide.
Why Choose This Product? Key Benefits
- ⏱️Stops All Life Stages: Excellent ovicidal action means it kills pest eggs, preventing future outbreaks before they hatch.
- ?️Dual Action Power: One product handles both Mites (Arachnids) and Insects, saving you the cost of mixing multiple chemicals.
- ⏳Deep Penetration: The EC formulation dissolves waxy protective webs and penetrates the underside of leaves where mites hide.
- ?️Contact & Stomach Action: Kills pests instantly upon contact and also eliminates larvae that feed on treated leaves.
- ?Crop Versatility: Approved for use on Tea, Cotton, Chilies, and Pulses, making it a staple for diverse farm needs.

How It Works: Mode of Action
Fosmite acts as a potent neurotoxin. It targets the nervous system of the pest, ensuring rapid control through a three-step process:
[Image of acetylcholinesterase inhibition mechanism]- Entry & Activation: The chemical enters the pest through direct contact or ingestion. Inside the insect, enzymes convert it into a more potent form (oxon).
- Enzyme Blockage: It irreversibly binds to the enzyme Acetylcholinesterase (AChE). This enzyme is responsible for "switching off" nerve signals.
- System Shutdown: With the enzyme blocked, nerve signals fire uncontrollably. This causes tremors, paralysis, and the eventual elimination of the pest.
Note: Because it attacks the nervous system, it is vital to rotate this product with other groups to prevent pests from building resistance.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Tea | Red Spider Mite, Purple Mite, Yellow Mite, Thrips, Scales |
| Cotton | Whitefly, Bollworms |
| Chilli | Mites (Yellow/Murda complex), Thrips |
| Soybean | Girdle Beetle, Stem Fly |
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) |
|---|---|---|---|---|
| Tea | 200 - 250 | 150 - 200 | 1.25 ml | Refer to Leaflet |
| Cotton | 600 - 800 | 150 - 200 | 4 ml | Refer to Leaflet |
| Chilli / Soybean | 600 - 800 | 150 - 200 | 4 ml | Refer to Leaflet |
| Gram / Pigeon Pea | 400 - 600 | 150 - 200 | 3 ml | Refer to Leaflet |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Check the product leaflet for specific days to ensure export compliance.
How to Apply: Best Practices
- Timing: For Tea, apply immediately after plucking to minimize residues. For other crops, spray at the first sign of infestation.
- Mixing: Fosmite is sensitive to alkaline (high pH) water. Do not mix with Bordeaux mixture or Lime Sulfur. Use a buffer if your water pH is high.
- Coverage: Mites hide under leaves. Ensure high-volume spraying to thoroughly coat the undersides of the foliage.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. This product is toxic to fish and bees; avoid spraying near water bodies or during active flowering.
Frequently Asked Questions
1. Does Fosmite kill mite eggs?
Yes. Fosmite has excellent ovicidal properties, meaning it kills mite eggs, larvae, and adults, preventing the population from bouncing back quickly.
2. Is it safe to use on export Tea?
Caution is advised. The European Union has very strict residue limits (0.01 mg/kg) for Ethion. Consult your local Tea Board guidelines before using Fosmite on tea intended for export to the EU.
3. Can I mix Fosmite with other fungicides?
It is generally compatible with many chemicals, but never mix it with alkaline products like Bordeaux mixture or Lime Sulfur, as this neutralizes the poison instantly.
4. What is the toxicity level of this product?
Fosmite carries a "Yellow Triangle" (Highly Toxic) label. It must be handled with care, kept away from children, and is harmful if swallowed or inhaled.
5. How does it help with resistance management?
Since it is an Organophosphate (Group 1B), it works well as a rotation partner for newer acaricides (like Spiromesifen or Fenazaquin) to delay the development of pest resistance.
