Active chemical class and ryanodine mode of action
- Anthranilic diamide class: Belongs to IRAC Group 28, operating through targeted binding to insect ryanodine receptors.
- Immediate feeding cessation: Uncontrolled release of calcium ions from intracellular stores causes rapid muscle contraction and paralysis; target larvae stop feeding within minutes.
- Ovi-larvicidal activity: Controls eggs and early-instar larvae, preventing crop foliage and stem damage before it begins.
- Formulation: Advanced Suspension Concentrate (18.5% SC) with excellent translaminar movement and rain-fastness within 2 hours.
CIBRC approved crops and target insect pests
Approved in India for Yellow stem borer and Leaf folder in rice; Early shoot borer and Top borer in sugarcane; American bollworm, Spotted bollworm, and Spodoptera in cotton; Diamondback moth in cabbage; and Fruit borer (Helicoverpa armigera) in tomato and chilli crops.
Application guidelines, dosage and safety
- Strictly follow the approved product label dose per acre; dilute in recommended water volume (typically 150 to 200 liters per acre for field crops).
- Apply at egg hatching or early larval emergence for maximum control.
- Favorable safety profile toward beneficial predators, parasitoids, and honeybees when applied as per label recommendations.
- Observe the mandatory Pre-Harvest Interval (PHI) printed on the container label.

Common questions
What is the active chemical ingredient in Coragen?
The active ingredient in Coragen is Chlorantraniliprole at an 18.5% SC (Suspension Concentrate) concentration.
How quickly does Coragen stop caterpillar feeding on crops?
Larvae stop feeding within 7 to 15 minutes of ingesting or contacting treated plant surfaces due to rapid muscle paralysis.
What is the rain-fastness duration of Coragen after spraying?
Coragen is rain-fast within approximately 2 hours after spray application once the chemical deposit has thoroughly dried on leaves.
