Chemical profile and mode of action
- Formulated as Acephate 75% Soluble Powder (SP), an organophosphate insecticide.
- Inhibits the enzyme acetylcholinesterase (AChE) in insect nerve junctions, causing continuous acetylcholine buildup and lethal nervous convulsions.
- Exhibits systemic translocation through leaves and stems, killing pests both through direct contact and upon ingestion of treated plant sap.
Target pests and labeled crop applications
- Cotton: Broad-spectrum control of bollworms (spotted bollworm, American bollworm) and sucking pests like aphids, jassids, and thrips.
- Paddy: Manages yellow stem borer, leaf folder, and green leafhopper during vegetative and reproductive growth phases.
- Vegetables (chilli, tomato): Controls aphids, fruit borers, and defoliating caterpillars.
- Acts as a versatile crop protection agent in resistance rotation programs when used judiciously.
