Product scienceHow It Works: Mode of Action

Lethal GR attacks the insect's nervous system by inhibiting the enzyme Acetylcholinesterase (AChE). This causes paralysis and eventual death of the pest.

  1. Contact Action: When soil pests (like termites) crawl through treated soil, the chemical penetrates their skin.
  2. Stomach Action: When pests eat plant roots or soil containing the granules, they are poisoned from the inside.
  3. Fumigant (Vapor) Action: The granules release a gas that travels through soil pores and plant stems, killing hidden borers that sprays cannot reach.

Note: This 3-way attack makes it highly effective against cryptic pests hiding deep in the soil or inside plant stems.

Useful detailsHow to Apply: Best Practices
  • Timing (Paddy): Apply 15-30 days after transplanting (early vegetative stage) or when "Dead Heart" symptoms appear.
  • Mixing: Mix the granules with a little sand or urea/fertilizer to ensure even distribution across the field.
  • Coverage (Paddy): Keep water outlets closed and maintain standing water (2-3 inches) for 3-5 days after application to let the gas work.
  • Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not use near fish ponds as it is toxic to aquatic life.
