Problems solved by technology

[0010] 3. Induce pest disease
[0012] However, the existing bio-pesticides on the market usually only work on specific pests or germs, etc., and have high requirements on temperature and humidity. The suitable temperature for the use of microbial-derived pesticides is 15-30°C; they are sensitive to ultraviolet rays, which are fatal to microbial-derived pesticides. The killing effect of the pesticide; the effect of the pesticide is slow, and the pests and diseases will not be effective immediately after the application, and the application time should be 2 to 3 days earlier than that of chemical pesticides, etc.

Embodiment 1

[0039] A kind of preparation method of biopesticide, concrete steps are as follows:

[0040] (1) First inoculate and cultivate the paracoccus paracoccus CGMCC1.12681 to obtain a fermentation broth, and then process it to make bacterial powder;

[0041] (2) Then, the discarded Hericium erinaceus rod is crushed into 100-mesh powder, then the powder, the bacterial powder obtained in step (1), acrylamide and sodium acrylate are added to water, and the ultrasonic vibration is uniform to obtain the premix;

[0042] (3) Then add a crosslinking agent and a photoinitiator to the premixed liquid and mix evenly, react with ultraviolet radiation, filter, wash, and dry to obtain a xerogel;

[0043] (4) Finally, add the dry gel into 1-octyl-3-methylimidazolium tetrafluoroborate, let it stand for 3 hours, and filter to obtain the biopesticide.

[0044] The specific method of step (1) is: first inoculate the paracoccus paracoccus CGMCC1.12681 in the PDA medium, the inoculum size is 3% (volum...

Embodiment 2

[0054] A kind of preparation method of biopesticide, concrete steps are as follows:

[0055] (1) First inoculate and cultivate the paracoccus paracoccus CGMCC1.12681 to obtain a fermentation broth, and then process it to make bacterial powder;

[0056] (2) Then the discarded Hericium erinaceus rods were crushed into 200-mesh powder, and then the powder, the bacterial powder obtained in step (1), acrylamide and sodium acrylate were added to water, and ultrasonically oscillated evenly to obtain a premix;

[0057] (3) Then add a crosslinking agent and a photoinitiator to the premixed liquid and mix evenly, react with ultraviolet radiation, filter, wash, and dry to obtain a xerogel;

[0058] (4) Finally, add the dry gel into 1-octyl-3-methylimidazolium tetrafluoroborate, let it stand for 2 hours, and filter to obtain the biopesticide.

[0059] The specific method of step (1) is: first inoculate the paracoccus paracoccus CGMCC1.12681 in the PDA medium, the inoculum size is 4% (vol...

Embodiment 3

[0069] A kind of preparation method of biopesticide, concrete steps are as follows:

[0070] (1) First inoculate and cultivate the paracoccus paracoccus CGMCC1.12681 to obtain a fermentation broth, and then process it to make bacterial powder;

[0071] (2) Then the discarded Hericium erinaceus rods were crushed into 200-mesh powder, and then the powder, the bacterial powder obtained in step (1), acrylamide and sodium acrylate were added to water, and ultrasonically oscillated evenly to obtain a premix;

[0072] (3) Then add a crosslinking agent and a photoinitiator to the premixed liquid and mix evenly, react with ultraviolet radiation, filter, wash, and dry to obtain a xerogel;

[0073] (4) Finally, add the dry gel into 1-octyl-3-methylimidazolium tetrafluoroborate, let it stand for 2 hours, and filter to obtain the biopesticide.

[0074] The specific method of step (1) is: first inoculate the paracoccus paracoccus CGMCC1.12681 in the PDA medium, the inoculum size is 3.5% (v...

Abstract

The invention relates to an application of Paracoccus sediminis CGMCC 1.12681 in preparation of a biopesticide. The Paracoccus sediminis CGMCC 1.12681 is prepared into the biopesticide for the first time, so that the growth and propagation of pathogenic bacteria can be effectively inhibited, and the growth of plants can be promoted. The effective component Paracoccus sediminis CGMCC 1.12681 has acompetitive effect with pathogenic bacteria on the one hand, and on the other hand, metabolites for inhibiting the pathogenic bacteria are generated, so that micro-ecological regulation and control are realized, diseases are effectively prevented and controlled, and plant growth is promoted.

Description

technical field [0001] The invention belongs to the technical field of biological pesticides, and relates to the application of paracoccus CGMCC1.12681 in the preparation of biological pesticides. Background technique [0002] Plant disease is one of the natural disasters that threaten crop production. More than 80% of plant diseases in production are caused by fungal infection. Poisoning seriously affects the national economy and people's lives. [0003] Chemical pesticides cause great damage to the ecology, chemical pesticides are not easy to degrade, and there are pesticide residues, which seriously threaten people's health. The pesticide residues in agricultural products and soil are getting higher and higher, which seriously reduces the quality of agricultural products; the density of beneficial organisms has decreased, and the natural community has been severely damaged; the resistance of pathogenic bacteria and pests has generally increased, leading to excessive use ...
