Buprofezin 25% SC acts as an insect growth regulator (IGR) with a specific mode of action. It inhibits chitin synthesis in insects, disrupting their normal development and moulting processes. Chitin is a key component in the exoskeleton of insects, and by interfering with its production, Buprofezin prevents insects from reaching maturity and hinders their ability to reproduce effectively. This mode of action specifically targets the nymph stages of insects, providing effective control over pests such as aphids, whiteflies, mealybugs, leafhoppers, and certain scales. By disrupting their growth and development, Buprofezin helps manage insect populations and minimize crop damage.
