The invention belongs to the technical field of biological control, and particularly relates to an
enterobacter ludwigii SLGJ4, a
fungicide and application of the
enterobacter ludwigii SLGJ4, the preservation number of the
enterobacter ludwigii SLGJ4 is CCTCC No: M 20251540, the
bacterial strain has broad-spectrum
antibacterial activity, and the antibacterial rates of the
bacterial strain on
Colletotrichum gloeosporioides of pomegranate,
Colletotrichum truncatum of pepper,
rhizoctonia cerealis of wheat and Botryis cinerea of tomato are 55.48%, 51.03%, 48.67% and 47.15% respectively; the
control effect on pomegranate fruit anthracnose is 60.99%, the
enzyme activity of defensive
enzyme POD of pomegranate fruits is remarkably improved, the activity of PPO is inhibited, and enzymatic
browning of the pomegranate fruits is delayed; after
colletotrichum gloeosporioides hyphae are treated by the strain SLGJ4, the growth of the hyphae is obviously inhibited In addition, the strain can also cause accumulation of
intracellular active oxygen of
colletotrichum gloeosporioides, destroy
plasma membrane integrity, has a
good control effect on pomegranate fruit anthracnose, and provides a theoretical basis for development of pomegranate biocontrol inoculants and preservatives.
