Embodiment 1

[0016] A preparation process of tangerine peel composite plant pesticide insecticide, comprising the following steps:

[0017] A, use organic solvent extraction time 3 hours with waste tangerine peel, temperature 55 ℃, extract three times; Adopt hollow fiber membrane filtration method and distillation method to extract, obtain tangerine peel extract;

[0018] B, the extract is mixed with compound matrine, capsaicin and rotenone;

[0019] C. Mix the above mixture evenly.

[0020] The organic solvent is ethanol with a mass fraction of 50%.

[0021] The compounded matrine is formed by compounding matrine and abamectin.

[0022] In the tangerine peel composite plant pesticide insecticide, the weight percentage of each raw material is as follows: 1.8% of compound matrine, 1.0% of capsaicin, 2.3% of rotenone, and the balance of tangerine peel extract.

Embodiment 2

[0024] A preparation process of tangerine peel composite plant pesticide insecticide, comprising the following steps:

[0025] A. Use the waste tangerine peel to extract with an organic solvent for 4 hours at a temperature of 40° C. and extract three times; use hollow fiber membrane filtration and distillation to extract to obtain the tangerine peel extract;

[0026] B, the extract is mixed with compound matrine, capsaicin and rotenone;

[0027] C. Mix the above mixture evenly.

[0028] Described organic solvent is the acetone that mass fraction is 75%.

[0029] The compounded matrine is formed by compounding matrine and abamectin.

[0030] In the tangerine peel compound plant pesticide insecticide, the weight percentage of each raw material is as follows: 0.5% of compound matrine, 1.5% of capsaicin, 0.2% of rotenone, and the balance of tangerine peel extract.

Embodiment 3

[0032] A preparation process of tangerine peel composite plant pesticide insecticide, comprising the following steps:

[0033] A. Use the waste tangerine peel to extract three times with an organic solvent for 2 hours at a temperature of 65° C.; extract by hollow fiber membrane filtration and distillation to obtain the tangerine peel extract;

[0034] B, the extract is mixed with compound matrine, capsaicin and rotenone;

[0035] C. Mix the above mixture evenly.

[0036] The organic solvent is ethanol with a mass fraction of 70%.

[0037] The compounded matrine is formed by compounding matrine and abamectin.

[0038] In the tangerine peel composite plant pesticide insecticide, the weight percentage of each raw material is as follows: 2.5% of compound matrine, 0.5% of capsaicin, 2.8% of rotenone, and the balance of tangerine peel extract.

Abstract

The invention provides a preparation method of a mandarin orange peel composite plant agricultural insecticide. The method comprises the following steps: preparing waste mandarin orange peel as a raw material; extracting mandarin orange alkaloid with an organic solvent; adding capsaicin, sophocarpidine and rotenone, and compounding into a wide-spectrum plant agricultural insecticide. The insecticide can be used for effectively preventing and controlling tetranychus cinnabarinus, panonychus citri, vegetable aphids, cabbage caterpillars, rice-stem borers, euproctis pseudoconspersa strands and empoasca flavescens, and has stomach killing and touch killing effects as a wide-spectrum insecticide. The insecticide is a safe, efficient, residue-free and nuisanceless plant-derived pesticide. The insecticide replaces chemical agricultural insecticides, and is a plant agricultural insecticide with a development prospect.

Description

technical field [0001] The invention relates to the technical field of insecticides, in particular to a preparation process of a tangerine peel composite plant pesticide insecticide. Background technique [0002] Pesticides play an important role in human resistance to pests and diseases, and in protecting crops with high yield and high-quality production. Since the advent of organic synthetic pesticides in the middle of the 20th century, they once played a huge role in promoting agricultural production due to their high efficiency, quick effect, and broad spectrum. However, due to the large-scale use of highly toxic and high-residue organic synthetic pesticides, in just a few decades, the negative impacts have been far beyond people's expectations, such as pest resistance, environmental pollution, and mass killing of beneficial organisms. etc. Biorational pesticides that are highly effective against pests and safe for the environment and non-target organisms have become t...
