Active ingredient and physiological mode of action
Chlorantraniliprole targets and activates ryanodine receptors located in insect muscle cells. This uncontrolled opening depletes intracellular calcium reserves, causing muscle contractions, rapid feeding cessation within hours, lethargy, paralysis, and pest mortality.
- Active constituent: Chlorantraniliprole 18.5% SC (Rynaxypyr active)
- Insecticide group: Anthranilic diamide (IRAC Group 28)
- Systemic movement: Translaminar and xylem systemic mobility protecting treated and expanding foliage
Target crops and major chewing pests
- Paddy (rice): Yellow stem borer (Scirpophaga incertulas) and leaf folder (Cnaphalocrocis medinalis).
- Sugarcane: Early shoot borer (Chilo infuscatellus) and top borer (Scirpophaga excerptalis).
- Corn and pulses: Fall armyworm (Spodoptera frugiperda) and gram pod borer (Helicoverpa armigera).
Application guidelines and safety standards
For optimum protection, apply during the early egg-hatching or early-instar larval stage using adequate water volume to ensure uniform crop deposition. Always follow official CIBRC label-recommended dosages, wear personal protective equipment, and observe the prescribed pre-harvest interval before crop harvesting.

Common questions
What is the active ingredient in FMC Coragen?
The active ingredient in Coragen is chlorantraniliprole 18.5% SC, an anthranilic diamide insecticide.
How does Coragen stop caterpillar damage so quickly?
It activates muscle ryanodine receptors, causing calcium depletion that halts pest feeding within hours of exposure.
What crops are officially approved for Coragen application?
CIBRC-approved crops include paddy, sugarcane, maize, cotton, pigeon pea, tomato, cabbage, and chili.
