Part 11/16:
Faced with widespread devastation, the response involved removing severely infected trees and sterilizing the soil—sometimes through chipping and burning—to prevent reinfection. Over time, researchers aimed to find genetically resistant Angsana varieties through rigorous screening: inoculating seedlings with fungi, observing survival, and propagating resistant strains via stem cuttings.
Successful development of these resistant plants marked a turning point. These younger trees, tested and proven to resist the fungi, are now being transplanted into urban landscapes, helping to preserve biodiversity and maintain ecological functions.
