Active ingredients and dual mode of action
Ampligo combats insect attacks through two complementary biochemical pathways.
- Chlorantraniliprole (Diamide - Group 28): Activates insect ryanodine receptors, depleting intracellular calcium reserves, leading to immediate feeding cessation and muscle paralysis.
- Lambda-cyhalothrin (Pyrethroid - Group 3A): Disrupts voltage-gated sodium channels in nerve axons, providing rapid knockdown upon contact.
- ZC Micro-Encapsulation: Slowly releases active molecules to extend protective duration even under intense rainfall or sunlight.
Approved target crops and insect pests
Registered under the Central Insecticides Board & Registration Committee (CIBRC) for heavy caterpillar and borer infestations.
- Cotton: American bollworm, spotted bollworm, and leaf-feeding caterpillars.
- Pigeon pea and pulses: Gram pod borer (Helicoverpa armigera) and pod fly.
- Maize: Fall armyworm (Spodoptera frugiperda) during vegetative and whorl stages.
- Rice: Yellow stem borer and leaf folder.
Spraying protocols and stewardship
Safe application practices preserve efficacy and prevent resistance in insect populations.
- Spray early at the initial egg-hatching or early larval instar stage before borers enter pods or stems.
- Calibrate spray equipment to ensure thorough canopy coverage with fine misting nozzles.
- Avoid repetitive sequential sprays; rotate with alternate chemical classes such as spinosyns or IGRs.
- Observe the approved pre-harvest interval (PHI) printed on the container label prior to harvest.

Common questions
What are the active ingredients in Ampligo?
Ampligo contains Chlorantraniliprole 9.3% and Lambda-cyhalothrin 4.6% in a ZC (micro-encapsulated suspension) formulation.
Is Ampligo effective against fall armyworm in maize?
Yes, Ampligo is approved and widely used for controlling fall armyworm larvae when sprayed into leaf whorls at early infestation.
What is a ZC formulation in crop protection?
A ZC formulation is a specialized blend of capsule suspension (CS) and suspension concentrate (SC), offering high rainfastness and prolonged residual activity.
