How It Works: Mode of Action
[Image of acetylcholinesterase inhibition mechanism]Lalwin works as a "Pro-Insecticide," meaning it transforms into an even more powerful compound once inside the insect.
- Ingestion & Contact: The pest absorbs the chemical by walking on treated leaves or eating them.
- Activation: Inside the insect's gut, enzymes convert Thiodicarb into methomyl, a potent toxin.
- System Shutdown: This toxin blocks the insect's nervous system (inhibiting the enzyme Acetylcholinesterase), causing paralysis, tremors, and rapid death.
Note: It also has excellent ovicidal action, drying up insect eggs before they can hatch into larvae.

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Since Lalwin is a powder, measurements are in Grams.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 300 - 400 g | 150 - 200 L | 2 g | 30 Days |
| Chilli | 250 - 400 g | 200 L | 1.5 - 2 g | 6 Days |
| Pulses (Black Gram/Pigeon Pea) | 250 - 400 g | 200 L | 1.5 - 2 g | 17 - 30 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting to ensure the crop is safe for consumption.
How to Apply: Best Practices
- Timing: Apply when you first see egg masses or small larvae. Do not wait for the pests to grow large.
- Mixing: Since this is a Wettable Powder (WP), mix it with a small amount of water to make a paste first, then add it to the full tank. Keep the tank water agitated (stirred) so the powder doesn't settle.
- Coverage: Ensure thorough coverage of foliage, especially the undersides of leaves where eggs are often laid.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not use alkaline mixtures (like Bordeaux mixture) with Lalwin.
