Active ingredient and per-acre coverage
Coragen contains chlorantraniliprole 18.5% SC (Rynaxypyr active), an anthranilic diamide insecticide (IRAC Group 28) that activates ryanodine receptors to halt caterpillar feeding within hours. The approved label dose for paddy stem borer and leaf folder is typically 60 ml per acre, meaning a single 150ml bottle covers approximately 2.5 acres of rice crop.
- Bottle capacity: 150 ml suspension concentrate
- Per-acre dose in paddy: 60 ml in 200 litres of clean water per acre
- Duration of control: Delivers 15 to 21 days of residual stem borer and leaf folder protection
Authenticating genuine bottles and avoiding fakes
- 3D security hologram: Check the manufacturer's color-shifting 3D hologram sticker on the bottle cap and seal.
- Unique QR code verification: Scan the printed QR code with smartphone apps to verify genuine batch authentication.
- Authorized retailer purchase: Always buy from licensed pesticide dealers and insist on a printed GST tax invoice with the batch number.
Application safety and pre-harvest interval
Apply during early larval hatching stages using a knapsack sprayer with hollow cone nozzles. Always observe CIBRC approved crop-specific pre-harvest intervals (PHI), such as 14 days in paddy and sugarcane, before harvesting produce.
