How It Works: Mode of Action
Kthion works as a powerful neurotoxin with both contact and stomach action.
- Enzyme Inhibition: Upon contact, Malathion inhibits the enzyme Acetylcholinesterase (AChE) in the insect's nervous system.
- System Overload: This blockage causes the accumulation of Acetylcholine, leading to continuous nerve firing.
- Elimination: The insect suffers from tremors, paralysis, and eventually dies due to nervous system failure.
Note: Mammals (humans/livestock) can detoxify Malathion faster than insects, providing a relative safety margin, though caution is always required.
Target Crops & Pests
| Crop / Application | Target Pest(s) |
|---|---|
| Paddy (Rice) | Rice Hispa |
| Cotton | Whitefly, Jassid, Thrips (Sucking Pests) |
| Public Health (Fogging) | Adult Mosquitoes (Vector Control) |
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 (Rice) | 460 ml | 200 L | 2.5 ml | 14 Days |
| Cotton | 600 ml | 200 L | 3 ml | N/A |
| Mosquito Fogging | 1 Part Chemical | 19 Parts Diesel | 1:19 Ratio | N/A |
*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 infestation (Economic Threshold Level). For mosquitoes, fogging is best done at dusk or dawn.
- Mixing: Ensure a stable white emulsion is formed when mixing with water. For fogging, mix thoroughly with diesel or kerosene.
- Coverage: Ensure thorough coverage of the crop canopy. For Rice Hispa, target the leaf folds where pests hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray near water bodies as it is toxic to fish.
