This invention discloses a strain of
Acinetobacter piterum and its application in the control of
bacterial wilt in tomatoes. The
Acinetobacter piterum provided by this invention (…
Acinetobacter pittii Acinetobacter pituitaria BB307, with accession number GDMCC NO. 67769, exhibits broad-spectrum
antibacterial activity against eight sequence variants of
Ralstonia solanaceae, making it suitable for controlling
bacterial wilt in tomatoes. Furthermore, it possesses
nitrogen-fixing,
phosphorus-solubilizing,
siderophore-producing, and indoleacetic acid-promoting abilities, which can promote
plant growth in tomatoes. The Acinetobacter pituitaria BB307 provided by this invention demonstrates synergistic potential for biocontrol and
growth promotion, offering a highly efficient microbial resource for
green production of solanaceous crops and providing a more economical, efficient, and
environmentally friendly solution for the prevention and control of
bacterial wilt.
