Evaluation of biocontrol agents for the management of sorghum anthracnose caused by <i>Colletotrichum sublineola</i>.

ABSTRACT: Sorghum anthracnose, caused by Colletotrichum sublineola, poses a severe threat to global sorghum production. In China, the rising demand for organic sorghum used in Baijiu brewing underscores the urgent need for effective biocontrol agents or microbial formulations, which remain scarce. In this study, we assessed the efficacy of six biofungicides and two microbial agents against sorghum anthracnose. All tested biocontrol agents and microbial inoculants significantly inhibited mycelial growth and spore germination of C. sublineola in vitro. Iron chlorin exhibited the lowest EC₅₀; values for inhibition mycelial growth and spore germination, followed by pterostilbene. In greenhouse trials, Pterostilbene and Iron chlorin significantly reduced disease severity, with co
