Embodiment 1

[0029] The invention discloses a bacillus pumilus for preventing and treating rice false smut, the bacillus pumilus is Bacillus pumilus ZHQN-6, and the preservation number is: 16565. The preservation date is: October 10, 2018, and the preservation unit is: Institute of Microbiology, Chinese Academy of Sciences. Preservation address: Institute of Microbiology, Chinese Academy of Sciences, No. 3, Yard 1, Beichen West Road, Chaoyang District, Beijing.

[0030] The screening method of the bacillus pumilus comprises the following steps:

[0031] Take soil samples in the paddy fields of the main rice production areas in various places, isolate the microbial strains that exist in the soil from the soil samples, and adopt the three-point confrontation culture method to carry out the confrontation experiment with the rice smut bacteria strain;

[0032] (1) Pour the culture medium suitable for the growth of pathogenic bacteria on the petri dish;

[0033] (2) put a diameter of 5mm aspe...

Abstract

The invention relates to the technical field of ustilaginoidea virens prevention and control, in particular to bacillus pumilus ZHQN-6 for preventing and controlling ustilaginoidea virens. According to the bacillus pumilus ZHQN-6 for preventing and controlling the ustilaginoidea virens, the preservation number is 16565. The bacillus pumilus has a good prevention and control effect on the ustilaginoidea virens, an experiment is carried out through a three-point confrontation culture method, and the result shows that the inhibition zone of the bacillus pumilus ZHQN-6 on the ustilaginoidea virensis 31.67 mm.

Description

technical field [0001] The invention relates to the technical field of rice smut disease prevention and control, in particular to a bacillus pumilus for preventing and treatment of rice smut disease. Background technique [0002] Rice false smut (Ustilaginoidea virens) is another disease that mainly affects rice production after the three major diseases of rice, rice blast, sheath blight and stripe leaf blight. With the acceleration of the renewal of rice varieties, the improvement of fertilization level, and the change of cultivation system, rice false smut will gradually increase, and in severe cases, it can cause 20% to 30% yield loss, which has a great impact on rice yield. The toxin produced by rice false smut bacteria has serious hidden dangers to the safety of rice eaten by humans and animals and the ecological security of the farmland environment, so rice false smut has been paid more and more attention. The history of rice smut damage is short and the research star...
