Chemical profile and axonic mode of action
- Type II synthetic pyrethroid: Active ingredient Lambda-cyhalothrin (IRAC Group 3A / Sodium Channel Modulator).
- Axonic disruption: Keeps voltage-gated sodium channels open in insect nerve membranes, causing repetitive nerve discharges, extreme hyperactivity, paralysis, and death.
- Repellent property: Deters adult insect moths from landing and laying eggs on treated crop foliage.
- Formulation types: 5% EC (Emulsifiable Concentrate) and modern 4.9% CS (Capsule Suspension) offering extended UV stability and rain-fastness.
CIBRC approved target crops and insect pests
Approved in Indian agriculture for managing Bollworms, Jassids, and Thrips in cotton; Stem borer and Leaf folder in rice; Shoot and fruit borer in brinjal and tomato; Pod borer in pigeonpea; and Thrips and Pod borers in chilli. Applying at early pest detection knocks down mobile insects rapidly, preventing extensive foliage and boll damage.
Application guidelines, dosage and safety
- Follow CIBRC approved label dosages strictly (typically 150 to 200 ml per acre in 200 liters of water for field crops).
- Apply using a fine hollow cone nozzle to achieve comprehensive canopy wetting.
- Observe the mandatory Pre-Harvest Interval (PHI) printed on the product packaging before harvesting produce.
- Wear personal protective gear and avoid spraying near water bodies, as pyrethroids are highly toxic to fish and aquatic life.

Common questions
What is the mode of action of Lambda-cyhalothrin insecticide?
It modulates voltage-gated sodium channels in insect nerve membranes, causing continuous nerve impulses, paralysis, and rapid knockdown.
What is the difference between an EC and a CS formulation of Lambda?
The CS (Capsule Suspension) formulation micro-encapsulates the active ingredient, providing longer residual control and reduced dermal irritation.
Is Lambda-cyhalothrin safe for honeybees and fish?
No. It is highly toxic to fish, aquatic organisms, and foraging bees; avoid spraying flowering crops during peak daytime pollination hours.
