Evaluating the biocontrol potential and whole genome sequencing of Pseudomonas fluorescens HT1: a promising agent against southern blight in Coptis chinensis

Abstract

Southern blight, caused by Sclerotium rolfsii, poses a formidable threat to the cultivation of Coptis chinensis, especially affecting both yield and crop quality. Given the environmental harm associated with chemical fungicides, microbial antagonists are emerging as a viable solution for plant disease management. This study aimed to identify bacterial strains with antagonistic properties against southern blight in Coptis chinensis and to evaluate their biocontrol capabilities.
