Introduction

Chlorpyrifos 50% E.C Insecticide is a broad-spectrum insecticide formulated as an emulsifiable concentrate (EC) containing 50% chlorpyrifos, an organophosphate insecticide that acts as a contact, stomach, and respiratory poison. By disrupting the acetylcholinesterase enzyme in the insect nervous system, chlorpyrifos prevents the breakdown of acetylcholine, a neurotransmitter essential for normal nerve function. This disruption leads to an accumulation of acetylcholine, causing overstimulation of nerve cells, paralysis, and eventual death of insects.

Active Ingredient and Mode of Action

The active ingredient in Chlorpyrifos 50% E.C Insecticide is chlorpyrifos, an organophosphate insecticide that is chemically similar to the natural insecticide paraoxon. When insects ingest, inhale, or come into contact with chlorpyrifos, it binds to acetylcholinesterase, an enzyme responsible for breaking down acetylcholine. This binding inhibits the activity of acetylcholinesterase, allowing acetylcholine to accumulate in the insect nervous system. The excess acetylcholine overstimulates nerve cells, leading to muscle tremors, paralysis, and respiratory failure.
