Bacillus amyloliquefaciens strain for preventing and controlling root rot of fruits and vegetables and its application.

The strain has a significant antagonistic effect on common pathogens that cause root rot of fruits and vegetables, especially for strawberry root rot, and has a strong ability to produce 3-indoleacetic acid (IAA) and siderophos. It can not only effectively prevent and cure root rot of fruits and vegetables, but also promote the absorption of nutrients by plants and promote plant growth.

The most suitable growth temperature for Bacillus amyloliquefaciens is 28-37 ℃.
Bacillus amyloliquefaciens is widely distributed in nature, not only can exist in soil, plant rhizosphere surface, deep sea water and the external environment, but also common in plants.
Bacillus amyloliquefaciens is non-toxic and harmless to humans and animals, and does not pollute the environment.
Bacillus amyloliquefaciens has abundant metabolites, has broad-spectrum antibacterial activity, strong resistance to stress, fast growth and good stability.

The extracellular enzymes produced by Bacillus amyloliquefaciens mainly include phytase, chitinase, glucanase, protease, amylase, rennet, etc. The main lipopeptide metabolites are surfcatian, Antagonistic active substances such as fengycin, litarin and Bacillo-my-cinD, also produce the plant growth hormone indole-3-acetic acid (IAA).

The growth and metabolism of Bacillus amyloliquefaciens produces active substances such as low molecular weight antibiotics and antibacterial protein polypeptides, which can inhibit pathogenic bacteria and nematodes; the active substances of most metabolites are thermally stable, insensitive to ultraviolet irradiation and protease treatment, and have acid and alkali resistance, etc.
