Karanjin: Botanical Power for Agriculture and Beyond
Introduction
Karanjin is a naturally occurring furanoflavonol extracted from the seeds of Pongamia pinnata, a leguminous tree native to India and other tropical regions. Known for its diverse bioactivities, Karanjin plays an important role in sustainable agriculture, pest control, and even traditional medicinal applications.
What is Karanjin?
Karanjin is a bioactive flavonoid with strong insecticidal, acaricidal, and antimicrobial properties. This makes it valuable in eco-friendly farming as a botanical pesticide. It is often used in organic agriculture to protect crops from pests while minimising environmental impact.
Key Benefits & Applications
