Biocontrol strain ZHR0 for prevention and control of sugarcane smut and application thereof

Abstract

The invention discloses a strain, and the strain is a Bacillus amyloliquefaciens ZHR0 strain collected in the China Center for Type Culture Collection (CCTCC) with a collection number of CCTCC NO:M 2014577. The invention further discloses a preparation method of ZHR0 biocontrol microbial inoculum. Experiments show that the control efficiency of the ZHR0 biocontrol microbial inoculum prepared by the preparation method to the sugarcane smut is up to 53.98%, which indicates that the Bacillus amyloliquefaciens ZHR0 strain has good prevention and control effects on the sugarcane smut.

Description

technical field

[0001] The invention belongs to the technical field of plant protection, and in particular relates to a biocontrol bacterial strain ZH0 for preventing and treating sugarcane smut and application thereof. Background technique

[0002] Sugarcane smut (sugarcane smut) is a fungal disease caused by Ustiliago scitaminea Sydow. It was first reported in Natal, South Africa in 1877, and the disease has become an important worldwide epidemic disease.
