Active chemical chemistry and dual action mechanism
This pre-mixed emulsifiable concentrate combines two complementary modes of neurotoxic action to overcome pest resistance and deliver rapid knockdown.
Chlorpyriphos acts as an acetylcholinesterase inhibitor causing continuous nerve firing, while Cypermethrin modulates voltage-gated sodium channels in insect nerve membranes.
- Chlorpyriphos (50% EC): Organophosphate delivering contact, stomach, and vapor action that flushes pests from hidden crevices.
- Cypermethrin (5% EC): Synthetic pyrethroid providing immediate knockdown and strong anti-feeding repellency.
- Synergistic performance: Combines speed of kill with residual foliar persistence against tough caterpillar complexes.
Approved crops and target insect spectrum
The dual active formulation is registered for suppressing complex pest infestations across commercial cash crops and field agriculture.
It is widely used in cotton for bollworms and foliar pests, as well as in rice for stem borers and leaf folders.
- Cotton: American bollworm, spotted bollworm, pink bollworm, whiteflies, aphids, and thrips.
- Paddy (Rice): Stem borer, leaf folder, and whorl maggot.
- Vegetables: Fruit and shoot borer in brinjal, diamondback moth in cabbage, and pod borers in pulses.
Application dilution and personal safety guidelines
Apply Chlorpyriphos 50% + Cypermethrin 5% EC upon observing pest thresholds, ensuring thorough canopy wetting with clean water.
Because organophosphates and pyrethroids pose acute exposure risks, applicators must observe strict chemical handling hygiene.
- Dilution protocol: Strictly adhere to container label dilution rates; avoid unauthorized heavy tank mixtures.
- Protective gear: Wear impervious chemical gloves, face shield, vapor mask, and full-body protective overalls during spraying.
- Environmental protection: Highly toxic to aquatic fauna and honeybees; avoid spraying near fish ponds or during peak flowering hours.

Common questions
What active ingredients are in Chlorpyriphos 50% + Cypermethrin 5% EC?
It contains Chlorpyriphos 50% (organophosphate) and Cypermethrin 5% (synthetic pyrethroid) in an emulsifiable concentrate formulation.
What insect pests does this combination insecticide control?
It controls bollworms, stem borers, leaf folders, aphids, whiteflies, and fruit borers across cotton, rice, and vegetables.
How does the dual mode of action benefit pest control?
It combines rapid pyrethroid knockdown with strong organophosphate vapor and contact kill, managing pests that exhibit single-class tolerance.
