Active Ingredient Content and Biochemical Mode of Action
Coragen contains modern diamide chemistry that selectively targets insect muscular receptors.
Key chemical characteristics:
- Active ingredient: Chlorantraniliprole (Rynaxypyr) formulated as a suspension concentrate at 18.5% w/w SC concentration.
- Ryanodine receptor activation: Stimulates uncontrolled release of intracellular calcium from the sarcoplasmic reticulum in muscle cells, causing rapid paralysis.
- Immediate feeding cessation: Caterpillars cease feeding within minutes of ingestion or contact, halting crop leaf and fruit damage.
- Ovi-larvicidal efficacy: Delivers potent activity on eggs and neonate larvae as they chew through treated eggshells.
Approved Target Crops and Borer Complex Controlled
Chlorantraniliprole is registered under CIBRC guidelines across key food, fiber, and commercial cash crops.
Major registered crop uses:
- Paddy (Rice): Controls yellow stem borer (Scirpophaga incertulas) and leaf folder (Cnaphalocrocis medinalis) during tillering and panicle development.
- Sugarcane: Applied as a directed sett drench or early foliar spray to control early shoot borer and top borer.
- Tomato and Vegetables: Manages tomato fruit borer (Helicoverpa armigera) and diamondback moth (DBM) in cole crops.
- Cotton and Soybean: Controls American bollworm, spotted bollworm, and Spodoptera litura caterpillars.
Application Guidelines and Safety Protocols
Timely application during early egg hatch or first instar larval stages optimizes control.
Safe spraying practices:
- Accurate dosage: Strictly measure according to official label directions using clean water for thorough canopy coverage.
- Translaminar rainfastness: Rapidly penetrates leaf cuticles and becomes rainfast within 2 hours of foliar drying.
- Beneficial arthropod safety: Has minimal impact on beneficial parasitoids, predatory bugs, and honeybees when applied per label.
- Protective gear: Wear personal protective equipment including rubber gloves, eye goggles, and a face shield during mixing.

Common questions
What is the technical content of Coragen insecticide?
Coragen contains Chlorantraniliprole 18.5% w/w SC, a specialized anthranilic diamide insecticide.
How does Coragen stop caterpillar damage on crops?
It activates insect muscle ryanodine receptors, depleting calcium and causing rapid muscle paralysis and feeding cessation within minutes.
Is Coragen safe for beneficial predatory insects?
Yes, chlorantraniliprole exhibits a favorable safety profile toward beneficial parasitoids, predatory mites, and pollinators when used per label.
