Dual Chemical Modes of Action
Shamir combines Novaluron (a benzoylurea insect growth regulator) with Indoxacarb (an oxadiazine sodium channel blocker) in a suspension concentrate.
Indoxacarb causes rapid cessation of feeding within hours through neurotoxic paralysis, while Novaluron inhibits chitin biosynthesis, preventing larvae from molting successfully into subsequent growth stages.
- Novaluron (5.25%): Chitin synthesis inhibitor acting as an ovicide and larvicide preventing successful ecdysis
- Indoxacarb (4.5%): Voltage-gated sodium channel blocker halting larval feeding within hours
- Complete life-cycle control: Controls eggs, newly emerged neonates, and mature voracious larval instars
Target Pests and Approved Crop Applications
Shamir is registered for controlling aggressive lepidopteran caterpillars across key commercial field and vegetable crops.
Foliar applications should be initiated when pest scouting reveals egg clusters or newly hatched early-instar larvae.
- Chilies: Controls fruit borer (Helicoverpa armigera) and tobacco caterpillar (Spodoptera litura)
- Tomato and cabbage: Manages fruit borers and diamondback moth (Plutella xylostella)
- Pulses and soybean: Suppresses pod borer complexes and semilooper infestations
Application Practices and Stewardship
Shake the bottle well before measuring and dilute in clean, debris-free water for application.
Apply using a well-calibrated knapsack sprayer with hollow cone nozzles to achieve complete droplet coverage on foliage and developing fruits.
- Early intervention: Spray at early larval hatching for maximum biological efficacy and minimal crop damage
- Foliar wetting: Ensure thorough coverage of lower leaf surfaces where egg clusters are deposited
- Safety gear: Wear protective gloves, protective clothing, and a face shield during mixing and spraying

Common questions
What are the active ingredients in ADAMA Shamir?
Shamir contains Novaluron 5.25% + Indoxacarb 4.5% SC in a suspension concentrate formulation.
How quickly does Shamir stop caterpillar feeding?
The Indoxacarb component paralyzes the insect nervous system, halting larval crop feeding within a few hours of ingestion.
Does Shamir kill insect eggs?
Yes, Novaluron provides potent ovicidal action, preventing viable larvae from hatching from exposed egg masses.
