Coragen insecticide is a modern crop protection product used by farmers to control a wide range of harmful insects, especially caterpillars that damage crops like rice, vegetables, and fruits. It works by affecting the muscles of insects, stopping them from feeding and causing them to die quickly. Coragen is known for its long-lasting effect, which helps protect crops for a longer time after spraying. It is also considered relatively safe for beneficial insects and the environment when used as directed. Farmers prefer it because it improves crop health, reduces damage, and helps increase overall yield.
