Embodiment 1

[0033] The preparation of embodiment 1 rice dregs residual oil fatty acid glyceride

[0034] S1: Mix the rice dregs and petroleum ether according to the ratio of solid to liquid 1g:7mL, extract for 3 hours at a temperature of 20°C and an oscillation rate of 120r / min, then suction filter, and place the obtained suction filtrate in a water bath Heat in the pot to remove the volatile solvent, and obtain the rice dregs residual oil extract;

[0035] S2: Add the rice dregs residual oil extract to the reaction kettle, and continue for 30 minutes at a temperature of 65°C and a vacuum of 0.12MPa to remove volatile impurities; wait until the temperature of the rice dregs residual oil extract drops to 50°C When adding 2% m / m of lipase RM IM and 10% m / m of glycerol, the vacuum is 0.10MPa, and the condition of feeding nitrogen is carried out to continue the reaction until the acid value of the rice dregs residual oil extract drops When it is below 4KOH / mg.g, the reaction is stopped, and ...

Embodiment 2

[0036] The preparation of embodiment 2 rice dregs residual oil fatty acid glyceride

[0037] S1: Mix rice dregs and petroleum ether according to the ratio of solid to liquid 1g:6mL, extract for 2 hours at a temperature of 25°C and an oscillation rate of 130r / min, then suction filter, and place the obtained suction filtrate in a water bath Heat in the pot to remove the volatile solvent, and obtain the rice dregs residual oil extract;

[0038] S2: Add the rice dregs residual oil extract to the reactor, and continue for 25 minutes at a temperature of 75°C and a vacuum of 0.09MPa to remove volatile impurities; wait until the temperature of the rice dregs residual oil extract drops to 60°C When adding 1% m / m of lipase and 5% m / m of glycerin, the vacuum is 0.08MPa, and the continuous reaction is carried out under the condition of feeding nitrogen, until the acid value of the rice dregs residual oil extract is reduced to 4KOH When the lipase RM IM is below 200 mesh, the reaction is ...

Embodiment 3

[0039] The preparation of embodiment 3 biological pesticides

[0040] Example 3 The biopesticide containing fatty acid glycerides of residual rice dregs comprises the following components in parts by weight: 20 parts of fatty acid glycerides of rice dregs residual oil, 35 parts of Bacillus soreunica, 64 parts of hydroxyapatite, and 16 parts of white carbon black , 20 parts of starch and an appropriate amount of water.

[0041] Preparation method: Mix fatty acid glycerides of residual oil from rice dregs, Bacillus suyunjin, hydroxyapatite, white carbon black, starch and water, stir evenly, carry out wet granulation, and make granules with a diameter of 0.2-0.4cm, and vacuum Drying until the water content is 5-10%wt, the biopesticide can be obtained.

Abstract

The invention discloses a biopesticide containing fatty acid glyceride of rice dregs and a preparation method thereof. The biological pesticide comprises the following components in parts by weight: 15-25 parts of fatty acid glycerides of rice dregs residue, 20-35 parts of Bacillus sorene, 80-100 parts of filler, 10-15 parts of binder and appropriate amount of water. The biopesticide of the present invention has wide insecticidal spectrum, high insecticidal activity, fast and stable insecticidal effect, long residual effect period, good killing effect on aged larvae, high efficiency, low toxicity, low residue, and environment-friendly. At the same time, the recycling of rice dregs and waste oil can be realized, which is in line with the concept of energy saving and environmental protection, and can promote the wider application of Bacillus thuringiensis.

Description

technical field [0001] The invention belongs to the technical field of biopesticide preparation, and in particular relates to a biopesticide containing fatty acid glyceride of rice dregs and a preparation method thereof. Background technique [0002] Biopesticide refers to a type of pesticide preparation that uses living organisms or their metabolites to control pests, germs, weeds, nematodes, rodents and other harmful organisms. Biological pesticides include microbial-derived pesticides, plant-derived pesticides, animal-derived pesticides and genetically modified Compared with chemical pesticides, biological pesticides have the following advantages: 1) strong selectivity, relatively safe for humans, animals and various beneficial organisms, and protect natural enemies; 2) have little impact on the ecological environment; 3) can induce pests Epidemics etc. [0003] Microbial pesticides are an important part of biopesticides. They are made from microbial groups whose metabol...
