Problems solved by technology

[0004] Patent CN201410086984.X discloses a water-dispersible granule of Bacillus amyloliquefaciens. Although the water-dispersible granule is easy to use, it can not only reduce the humidity of the air compared with the water, but also reduce dust pollution compared with the powder, but the water-dispersed Granules need to absorb water and disintegrate to exert their medicinal effect after spreading, and the effect is slow, especially for the control of crop foliar diseases.

Embodiment 1

[0033] Bacillus amyloliquefaciens parent powder selection 3 × 10 11 Live spores per gram of Bacillus amyloliquefaciens parent powder, methylated vegetable oil is methylated rapeseed oil, emulsifier is nonylphenol polyoxyethylene ether TX-6, and suspending agent is ethylhexyl palmitate.

[0034] Add 150g Bacillus amyloliquefaciens mother powder, 580g methyl esterified vegetable oil, 100g emulsifier, 25g suspending agent into SHR-100A mixer, mix at 650rpm for 5min, and use GM2000 / 4 high shear colloid mill to wet mill for 10min , to obtain Bacillus amyloliquefaciens oil suspension.

Embodiment 2

[0036] Taking Example 1 as a contrast, the setting of Suspending Aid Consumption is 30g Example 2, and all the other materials and operations are identical to Example 1.

[0037] Add 150g of Bacillus amyloliquefaciens mother powder, 580g of methyl esterified vegetable oil, 100g of emulsifier, and 30g of suspending agent into the SHR-100A mixer, mix at 650rpm for 5min, and use GM2000 / 4 high shear colloid mill to wet mill for 10min , to obtain Bacillus amyloliquefaciens oil suspension.

Embodiment 3

[0039] Taking Example 1 as a comparison, the suspending agent is set to use ethylhexyl methoxycinnamate instead of ethylhexyl palmitate in Example 3, and the rest of the materials and operations are exactly the same as in Example 1.

[0040] Add 150g Bacillus amyloliquefaciens mother powder, 580g methyl esterified vegetable oil, 100g emulsifier, 25g suspending agent into SHR-100A mixer, mix at 650rpm for 5min, and use GM2000 / 4 high shear colloid mill to wet mill for 10min , to obtain Bacillus amyloliquefaciens oil suspension.

Abstract

The invention discloses a bacillus amyloliquefaciens oil suspending agent, and relates to the technical field of oil suspending agents. The oil suspending agent is prepared from the following components in parts by weight: 1-20 parts of 5*10<10>-5*10<12> live spores / gram of Bacillus amyloliquefaciens concentrated powder, 50-70 parts of methyl esterified vegetable oil, 5-20 parts of an emulsifier and 1-10 parts of a suspending agent. According to the bacillus amyloliquefaciens oil suspending agent, bacillus amyloliquefaciens is evenly suspended in the diluent methyl esterified vegetable oil, storage stability and pourability are good, the utilization rate of active ingredients is high, the agent is convenient to apply and takes effect quickly, and tests show that the prepared bacillus amyloliquefaciens oil suspending agent has obvious control effect on tobacco bacterial wilt and tomato bacterial wilt.

Description

Technical field: [0001] The invention relates to the technical field of oil suspensions, in particular to a Bacillus amyloliquefaciens oil suspension. Background technique: [0002] Bacillus amyloliquefaciens (Bacillus amyloliquefaciens) is a species of Bacillus, a gram-positive bacterium widely distributed in nature, has a strong production capacity of secondary metabolites, and can produce a variety of antibacterial related metabolite. [0003] Applying Bacillus amyloliquefaciens to 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 active substances such as antibacterial proteins, antibiotics, enzymes or polypeptides, promote plant growth, and prevent and control plant fungi and bacterial diseases. Because Bacillus amyloliquefaciens can secrete a variety of antibacterial active substances, it has a wide range of resistance to pat...
