Technical chemistry and ryanodine receptor activation
Coragen contains Chlorantraniliprole 18.5% SC, an active ingredient pioneering the anthranilic diamide chemical class (IRAC Group 28).
It works by binding with high selectivity to ryanodine receptors in insect muscle cells, stimulating uncontrolled release of internal calcium ions. This triggers immediate muscle contraction, feeding cessation within minutes, lethargy, paralysis, and complete mortality over 2 to 4 days.
- Active chemical: Chlorantraniliprole 18.5% w/w SC.
- IRAC classification: Group 28 (Ryanodine receptor modulator).
- Immediate feeding cessation: Caterpillars cease feeding immediately upon ingesting treated plant tissue, halting crop damage.
Target crops and approved pest spectrum
Coragen is registered across major Indian field crops, commercial cash crops, and high-value vegetables.
It is celebrated for providing extended residual control against tough boring pests that traditional chemistries fail to reach.
- Sugarcane: Early shoot borer and top borer (applied as a directed soil drench over planted setts or ratoons).
- Paddy (Rice): Yellow stem borer (Scirpophaga incertulas) and leaf folder (Cnaphalocrocis medinalis).
- Maize: Fall armyworm (Spodoptera frugiperda) during early vegetative stages.
- Vegetables (Tomato, Brinjal, Cabbage): Fruit and shoot borer and diamondback moth.
Application methods, dilution, and safety directions
In paddy, maize, and vegetables, Coragen is applied as a foliar spray during early egg-hatching windows before borers penetrate internal plant tissues.
In sugarcane, it is applied as a directed soil drench along the cane furrow using a coarse nozzle without a swirl plate.
Follow label recommended water volume and dilution rates strictly, wearing protective gloves and face mask during application.
- Foliar spray: Uniform canopy coverage using hollow cone nozzles operated at container label recommended dilution rates in clean water.
- Soil drenching in sugarcane: Drench along the sett furrow with adequate soil moisture followed by light irrigation.
- Safety profile: Favorable safety profile for beneficial predatory insects, honeybees, and earthworms when used according to approved label directions.

Common questions
What is the technical active ingredient in Coragen insecticide?
Coragen contains Chlorantraniliprole 18.5% w/w SC, belonging to the anthranilic diamide chemical class.
How does Coragen stop caterpillar feeding so quickly?
It activates ryanodine receptors in insect muscle cells, releasing internal calcium and causing immediate muscle paralysis and feeding cessation.
How is Coragen applied in sugarcane crops?
In sugarcane, it is applied as a directed soil drench over planted setts or ratoon shoots within 30 to 45 days of planting under moist soil conditions.
