Problems solved by technology

The currently commonly used pesticides are highly toxic or highly toxic chemical pesticides. These pesticides have different degrees of residues in the harvested grains and vegetables. long-term serious impact on the environment
[0003] In order to overcome the harm of these chemical pesticides and develop organic ecological agriculture, people have developed biopesticides. The advantages of existing biopesticides are low toxicity, basically no residue in crops, and environmental friendliness. The broad spectrum of insecticide is not enough, and the cost is high, which limits its wide use

Embodiment 1

[0026] Raw materials: 45% castor cake, 10% cottonseed cake, 5% fresh stems and leaves of Lala rattan, 1:1:1 weight ratio of isatis root, salvia miltiorrhiza, and astragalus extraction residue 15%, livestock and poultry manure 25% , wherein Radix Radix Isatidis, Salvia Miltiorrhiza and Radix Astragali are all extracted with conventional water.

[0027] The preparation method is as follows: measure various raw materials in proportion, pulverize and mix them, put the mixed raw materials into a biogas pit for fermentation, the fermentation temperature of the biogas pit is 25 to 35° C., and the fermentation time is 5 days. After taking out, dry, crush and pass through a 20-mesh sieve to obtain the product.

[0028] After HPLC-MS detection and analysis, the product contained 0.45% ricinine.

[0029] HPLC chromatographic conditions: the column is ACQUITY UPLC? BEH C 18 Column (2.1 mm×100 mm I.D, 1.7 μm, Waters, USA), flow rate is 0.25 mL / min, column temperature is 40 °C, sample cha...

Embodiment 2

[0032] Raw materials: 40% of castor cake, 10% of cottonseed cake, 5% of fresh stems and leaves of Lala rattan, extracts of Radix isatidis, Salvia miltiorrhiza, and Radix Astragali with a weight ratio of 1:1:1 (extracted by medicinal ingredients, that is, alcohol extraction ) 15% of the remaining waste residue and 30% of livestock and poultry manure.

[0033] The preparation method is as follows: measure various raw materials in proportion, pulverize and mix them, put the mixed raw materials into a biogas pit for fermentation, the fermentation temperature of the biogas pit is 25 to 35° C., and the fermentation time is 5 days. After taking out, dry, crush and pass through a 20-mesh sieve to obtain the product.

[0034]

Embodiment 3

[0036] Raw materials: 40% castor cake, 10% cottonseed cake, 5% fresh stems and leaves of Lala rattan, the weight ratio is 1:2:2, 1:2:1, 2:1:1, 2:2 respectively : 1, 1: 1: 1 Radix Radix, Danshen, and Radix Astragali (extracted by medicinal ingredients, extracted with water), 15% of the remaining waste residue and 30% of livestock and poultry manure.

[0037] The preparation method is as follows: measure various raw materials in proportion, pulverize and mix them, put the mixed raw materials into a biogas pit for fermentation, the fermentation temperature of the biogas pit is 25 to 35° C., and the fermentation time is 5 days. After taking out, dry, crush and pass through a 20-mesh sieve to obtain the product.

[0038] The results show that when the ratio of Radix Isatidis, Salvia Miltiorrhiza and Radix Astragali is 1:1:1, the insecticidal rate and yield increase are higher than those of other ratios. Therefore, the ratio of the three is 1:1:1 for the test. .

Abstract

The invention discloses a biologic pesticide composition and a preparation method thereof. The biologic pesticide composition is prepared by fermenting raw materials comprising 25-45wt% of castor cake, 5-10wt% of cottonseed cake, 5-10wt% of fresh stem and leaf of Humulus japonicus, 10-20wt% of traditional Chinese medicine extraction waste residue and 25-45wt% of livestock and poultry night soil. The traditional Chinese medicine extraction waste residue comprises waste residue obtained after extracting isatis root, Salvia miltiorrhiza and Radix Astragali. The above biologic pesticide overcomes the disadvantages of present biologic pesticides, has insect killing and preventing effects, has no residual in harvested crops, and has a fertilizer effect as a pesticide in order to increase the yield of crops.

Description

technical field [0001] The invention relates to a biopesticide, in particular to a biopesticide prepared by fermenting castor cake, cottonseed cake and traditional Chinese medicine extraction residue as raw materials. Background technique [0002] In order to deal with the serious damage of crops by diseases and insect pests, pesticides are used in different growth stages of food crops, especially vegetable crops. The currently commonly used pesticides are highly toxic or highly toxic chemical pesticides. These pesticides have different degrees of residues in the harvested grains and vegetables. long-term serious impact on the environment. [0003] In order to overcome the harm of these chemical pesticides and develop organic ecological agriculture, people have developed biopesticides. The advantages of existing biopesticides are low toxicity, basically no residue in crops, and environmental friendliness. The broad spectrum of insecticide is not enough, and the cost is rel...
