Characterization of Two Potential Biocontrol <i>Bacillus</i> Strains Against Maize Stalk Rot.

ABSTRACT: Maize stalk rot (MSR) is one of the most devastating fungal diseases affecting maize worldwide. In recent years, biological control agents have emerged as an environmentally friendly and highly attractive strategy for managing MSR. In this study, two Bacillus strains-B. subtilis KP3P9 and B. siamensis K13C-were shown to effectively inhibit the growth of the MSR pathogen Fusarium graminearum in vitro. Pot experiments showed that inoculation with KP3P9 significantly increased plant height, stem width, above-ground part fresh weight, and total plant fresh weight, whereas K13C significantly improved the stem width and under-ground part fresh weight of maize seedlings (p < 0.05), demonstrating their plant-growth-promoting potential. Moreover, both strains mark
