Active Chemistry and Dual Action Mechanism
Ampligo unites two distinct chemical modes of action: an anthranilic diamide (Chlorantraniliprole) and a synthetic pyrethroid (Lambda-cyhalothrin). Chlorantraniliprole binds to insect ryanodine receptors (IRAC Group 28), releasing uncontrolled calcium ions from muscle reserves and inducing rapid feeding cessation and muscle paralysis.
Lambda-cyhalothrin acts on voltage-gated sodium channels in nerve membranes (IRAC Group 3A), preventing nerve signal transmission and delivering instantaneous contact knockdown upon exposure.
- Dual-Action Chemistry: Delivers simultaneous neuro-toxic contact knockdown and muscle receptor systemic feeding cessation.
- Patented ZC Formulation: Micro-encapsulated Lambda-cyhalothrin mixed with aqueous Chlorantraniliprole ensures UV stability and rainfastness.
- Broad Ovi-Larvicidal Activity: Affects both hatching eggs and active larval instars before they bore into stems or fruit tissues.
Target Caterpillars and Labeled Crops
Ampligo is officially registered under CIBRC for controlling damaging lepidopteran pests across key cash and pulse crops. Its systemic absorption prevents internal fruit and boll feeding that causes direct market yield loss.
Key controlled insect pests include Helicoverpa armigera (gram pod borer / American bollworm), Spodoptera frugiperda (fall armyworm), Spodoptera litura (tobacco caterpillar), and Leucinodes orbonalis (shoot and fruit borer) in maize, cotton, pigeon pea, and vegetables.
- Maize Protection: Highly effective against invasive fall armyworm feeding deep in the leaf whorl.
- Cotton Pest Management: Suppresses bollworm complexes while reducing sucking pest flare-ups when applied at recommended timings.
- Pulse Defense: Prevents pod borer entry during pod formation in pigeon pea, chickpea, and black gram.
Field Application and Stewardship Practices
For maximum efficacy, spray Ampligo at early egg hatching or during first-to-second instar larval emergence before caterpillars tunnel into pods, bolls, or stalks. Use calibrated hollow cone or flat fan nozzles with adequate spray volume to ensure full foliage wetness.
Rotate Ampligo applications with insecticides possessing non-cross-resistant modes of action (such as avermectins, spinosyns, or benzoylureas) to maintain long-term insect susceptibility and safeguard chemical longevity.
- Rainfast Property: The micro-encapsulated formulation achieves rainfastness shortly after drying on the leaf cuticle.
- Pre-Harvest Interval (PHI): Consult the official approved product container leaflet for crop-specific harvest waiting windows.
- Protective Gear: Always handle concentrate and spray mixture wearing rubber gloves, masks, and eye protection.

Common questions
What is the technical composition of Syngenta Ampligo?
Ampligo contains Chlorantraniliprole 9.3% + Lambda-cyhalothrin 4.6% ZC (a mixed formulation of capsule suspension and suspension concentrate).
How does Ampligo stop insect feeding so quickly?
Chlorantraniliprole activates ryanodine receptors to deplete cellular calcium, causing muscular paralysis within minutes, while Lambda-cyhalothrin disrupts nerve sodium channels for immediate knockdown.
Can Ampligo be used against Fall Armyworm in maize?
Yes, Ampligo is registered and widely utilized for controlling fall armyworm (Spodoptera frugiperda) larvae in maize crops.
