Embodiment 1

[0017] 1,000,000,000 CFU / g Bacillus atrophaeus · 0.5% lentinan aqueous suspension preparation: by mass percentage (except Bacillus atrophaeus).

[0018]

[0019] Preparation method: according to the formula, weigh the above components (except Bacillus atrophaeus) in proportion, put them into a ball mill and grind them for 30 minutes, filter, pump them into a dispersion tank for 3 minutes at high speed, and then grind them fully with a sand mill to control the solid components. The particle diameter is within 2 microns. After grinding, weigh and introduce the mother liquor of Bacillus atrophaeus, stir evenly, pump it into the dispersion tank for 3 minutes at high speed, and filter to obtain the suspension product.

Embodiment 2

[0021] 1,000,000,000 CFU / g Bacillus atrophaeus · 0.8% lentinan aqueous suspension preparation: by mass percentage (except Bacillus atrophaeus).

[0022]

[0023] Preparation method, with embodiment 1.

Embodiment 3

[0025] 1 billion CFU / g Bacillus atrophaeus · 1% lentinan aqueous suspension preparation: by mass percentage (except Bacillus atrophaeus).

[0026]

Abstract

The invention discloses a sterilizing composite of bacillus atrophaeus and lentinan. The sterilizing composite comprises effective ingredients of bacillus atrophaeus and lentinan, wherein the content of bacillus atrophaeus is one hundred million to five billion CFU/g; the mass percent of lentinan is (0.1-1.5)%. The sterilizing composite is prepared by compounding bacillus atrophaeus and lentinan and can be used for preventing and treating tobacco bacterial wilt disease and virus disease of tobacco, and the sterilizing composite has good preventing and treating effects; meanwhile, the sterilizing composite can improve the tobacco resistance and improve the tobacco yield and quality, and moreover, the sterilizing composite is safe to human, animal, beneficial organisms and environment.

Description

technical field [0001] The invention belongs to the field of agricultural bactericides, in particular to a bactericidal composition of bacillus atrophaeus and lentinan. Background technique [0002] Bacillus atrophaeus (Bacillus atrophaeus) was formerly known as Bacillus subtilis black var. Smith et al. discovered the original strain of Bacillus atrophaeus—NRS-1221A in 1952. This strain can produce melanin on a medium containing tyrosine. According to this characteristic, it is classified into the new species of Bacillus subtilis black var. . In 1989, Nakamura proposed to change the black variant of Bacillus subtilis to Bacillus atrophaeus to distinguish it from Bacillus subtilis. Bacillus atrophaeus can produce spores to resist adverse environments. It has strong resistance and can survive in a temperature environment above 80°C. It has broad application prospects in the fields of agriculture, industry, medical treatment, and sanitation. [0003] Lentinan is a kind of gl...
