Abstract

The invention relates to a microbial preparation for preventing and treating soil-borne diseases of fruits and vegetables as well as a preparation method and application of the microbial preparation.The microorganism is bacillus, in particular TB918; The microbial preparation has an excellent control effect on pathogenic bacteria causing fruit and vegetable diseases, such as phytophthora capsici, rhizoctonia solani, botrytis cinerea and pythium aphanidermatum.

Description

technical field [0001] This application belongs to the field of biological preparations, in particular to the field of microbial preparations. Background technique [0002] Soil-borne diseases refer to infectious diseases that occur in the roots or stems of plants and use soil as the medium of transmission, such as: damping-off, root rot, bacterial wilt, and fusarium wilt. Its harm is huge, causing the quality of fruits and vegetables to decline, greatly reducing production or even failing to harvest. At present, chemical agents are mainly used to prevent and control soil-borne diseases of fruits and vegetables. With the long-term use of chemical agents, pesticide residues have caused serious consequences such as environmental pollution, ecological balance damage, and human safety threats. With the enhancement of people's awareness of environmental protection, the emphasis on food safety issues and the requirements of sustainable agricultural development, efficient and safe...
