The invention belongs to the technical field of agricultural biocontrol, and especially relates to a broad-spectrum
disease resistance bacillus and an application thereof. The biocontrol bacillus is classified and named as
Bacillus velezensis, and the preservation number is CGMCC. No.15766. The
Bacillus velezensis has the advantages of broad antibacterial spectrum, strong antagonistic effect, longlasting period, and effectiveness in inhibition of the growth of
crop pathogenic fungi, and can be used in the fields of agricultural biocontrol to prevent and control
crop diseases caused by gray mold,
blight, anthracnose,
stem rot,
seedling blight, stalk break, gibberellic
disease and other fungi. The
Bacillus velezensis can also be used for promoting the growth of
crop seeds and seedlings andthe preservation and fresh-keeping of
fruits and vegetables. The Bacillus velezensis has the characteristics of strong resistance to
ultraviolet and drought, simple preparation method and low cost, isa biocontrol strain with excellent performance, and has good development and application prospects.
