Biocontrol effects of <i>Bacillus velezensis</i> and <i>Bacillus subtilis</i> against strawberry root rot caused by <i>Neopestalotiopsis clavispora</i>.

ABSTRACT: Strawberry root rot, caused by Neopestalotiopsis clavispora, is an emerging disease that seriously threatens the sustainable development of the strawberry industry. To develop eco-friendly control strategies, three antagonistic bacterial strains were screened from healthy strawberry plants and rhizosphere soils. Based on morphological characteristics, physiological and biochemical identification, and 16S rDNA sequence analysis, the isolates QY-4 and QJ-3 were identified as Bacillus velezensis, while TT-3 was identified as Bacillus subtilis. The results indicated that the cell-free culture filtrates of QY-4, QJ-3, and TT-3 significantly inhibited the hyphal growth of N. clavispora by disrupting cell membrane integrity, with inhibition rates of 63.29, 69.4, and 73
