"Chlorpyrifos 10g" refers to a granulated insecticide containing 10% chlorpyrifos, which works by inhibiting the enzyme acetylcholinesterase, leading to insect death through contact, stomach, or respiratory action. This slow-release formulation is used to control pests like termites, stem borers, and gall midges in crops such as rice and in soil. It is applied as a granule for easy application and to prevent drift, providing long-lasting protection.
