How It Works: Mode of Action
Cythion works by targeting the nervous system of insects. It is a non-systemic, broad-spectrum insecticide with stomach, contact, and respiratory (fumigant) action.
- Entry: The insect absorbs the chemical through its skin (cuticle) or eats treated leaves.
- Activation: Inside the insect, the chemical converts into "Malaoxon," a potent enzyme inhibitor.
- Paralysis: It blocks the insect's ability to stop nerve signals (inhibiting cholinesterase), leading to paralysis and rapid death.
Note: Mammals (humans) have enzymes to break down Malathion safely, making it much safer for us than for insects.

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) |
|---|---|---|---|---|
| Paddy | 460 ml | 200 L | 2.3 ml | 14 |
| Cotton | 600 - 800 ml | 200 L | 3 - 4 ml | 7 - 10 |
| Vegetables (Okra/Brinjal) | 400 - 600 ml | 200 L | 2 - 3 ml | 3 - 7 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray during the cool hours of the morning or late evening to avoid evaporating the chemical and to protect honeybees.
- Mixing: Do NOT mix with alkaline products like Bordeaux mixture or Lime Sulfur, as this will destroy the effectiveness of Cythion instantly.
- Coverage: Ensure full coverage of the plant foliage. The fumigant action helps, but good contact is key.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Cythion smell bad like old Malathion?
No. Cythion uses "Low Odor" technology and high-purity ingredients, significantly reducing the foul garlic smell associated with generic malathion.
2. Can I use Cythion for mosquito control?
Yes. Cythion is approved for public health use. It is widely used in fogging operations to control adult mosquitoes responsible for Malaria and Dengue.
3. Is it safe for vegetable crops?
Yes, it is excellent for vegetables because it has a short residual effect. This means the chemical breaks down quickly, making the produce safe to eat after a few days (observe the PHI).
4. Can I mix Cythion with other pesticides?
It is compatible with many insecticides and fungicides (like wettable sulfur) but strictly incompatible with alkaline materials (Bordeaux mixture).
5. Why is it called "Premium Grade"?
Coromandel removes harmful impurities (like isomalathion) during manufacturing. This makes Cythion safer for the applicator and more stable in storage compared to standard technical malathion.
