Researchers tested a natural approach to protect chickpea crops from a harmful soil fungus called Sclerotium rolfsii. They combined three natural substances: charred rice husks (biochar), an extract from the Cassia fistula plant, and a beneficial fungus called Trichoderma harzianum. The results showed this combination significantly reduced disease by 45% while also making plants grow stronger and healthier, offering farmers an eco-friendly alternative to chemical fungicides.
