Bacillus amyloliquefaciens is a kind of Bacillus, which is highly related to Bacillus subtilis. During its growth, it can produce a series of metabolites that can inhibit the activity of fungi and bacteria. Bacillus amyloliquefaciens had a good inhibitory effect on Banana Fusarium wilt; Polyketone compounds produced by Bacillus amyloliquefaciens can control pear fire blight caused by Erwinia. Bacillus amyloliquefaciens has good control effect on fruit blight caused by Phytophthora capsici; Bacillus amyloliquefaciens ch-2 could inhibit the mycelial growth and sclerotia formation of Sclerotinia sclerotiorum; Bacillus amyloliquefaciens K6 inhibited Micrococcus garciniae and Escherichia coli; Bacillus amyloliquefaciens has antagonism and control effect on Fusarium oxysporum, the pathogen of Cucumber Fusarium wilt. Bacillus amyloliquefaciens has broad-spectrum disease resistance, high bacterial content, high activity and strong stability. After application, it has remarkable disease resistance and yield increase effect. Bacillus amyloliquefaciens also has stress resistance, anti-aging and growth promotion; Improve soil and improve fertility; Reduce agricultural residues, high quality and increase production. The mechanism of Bacillus amyloliquefaciens mainly includes secreting substances, producing antagonism, competition between nutrition and space, inducing host resistance and promoting plant growth.
Bacillus amyloliquefaciens is a Gram-positive bacterium widely distributed in nature, which has strong application potential. Bacillus amyloliquefaciens belongs to the genus Bacillus. It is named Bacillus amyloliquefaciens because it can produce liquefied amylase to decompose starch. Applying Bacillus amyloliquefaciens into soil or water can degrade some toxic substances in nature and purify polluted soil, rivers and lakes. Bacillus amyloliquefaciens is a typical plant growth promoting bacterium, which can secrete antibacterial proteins, enzymes or peptides to promote plant growth and control plant fungal diseases. Because Bacillus amyloliquefaciens can secrete a variety of antibacterial substances, it has extensive resistance to bacteria on the surface of fruits and vegetables, and can solve the problems of fresh-keeping and long-term storage of fruits and vegetables.
Efficacy of Bacillus amyloliquefaciens
1.Disease resistance, bacteriostasis, broad spectrum and high efficiency:
Bacillus amyloliquefaciens has a significant control effect on soil borne diseases such as tomato leaf mold, early blight, Botrytis cinerea, cucumber fusarium wilt, anthrax, Melon Fusarium wilt, pepper late blight, wheat, rice sheath blight, corn spot, soybean root rot and so on.
2.Anti stress, anti-aging and promoting growth:
Bacillus amyloliquefaciens can induce crops to produce superoxide dismutase (SOD), add polyphenol oxidase (PPO), peroxidase (POD) and so on, and improve crop stress resistance; It can induce plants to secrete endogenous auxin rapidly, promote rapid rooting of crops, improve root development ability and promote robust growth of plants.
3. Improving soil fertility:
Bacillus amyloliquefaciens can improve crop rhizosphere microecology, activate insoluble phosphorus, potassium and other potential nutrients in soil, improve soil, loosen and harden, curb soil degradation and improve soil fertility.
4.Reduce agricultural residues and increase production with high quality:
Bacillus amyloliquefaciens can degrade residual pesticides in soil and fruits, reduce nitrite content, improve vitamin and sugar content of fruits and vegetables, improve the quality of agricultural products, improve crop yield, and be easy to store and transport. Improve and prolong fertilizer efficiency and reduce the amount of chemical fertilizer.
