Preliminary study on leaf blight and screening of as a biocontrol agent.

Introduction: This study aimed to identify the pathogen responsible for leaf blight in , investigate its biological characteristics, and identify effective synthetic fungicides. Additionally, this study examined changes in physiological and biochemical indices of leaves following pathogen infection and screened biocontrol bacteria that inhibit the pathogen growth, providing a scientific basis for preventing and managing leaf blight in .

Methods: Pathogens were isolated from the interface of healthy and infected leaf tissues and identified through morphological and molecular biological methods.
