Description

Technical Field

[0001] This invention relates to the fields of traditional Chinese medicine agriculture, biological plant protection, and green pesticide technology, specifically to a broad-spectrum insect-repellent plant protection preparation derived from traditional Chinese medicine and its ultrasonic extraction preparation method. Background Technology

[0002] In current agricultural production, the long-term and excessive use of chemical pesticides has led to increasingly serious problems such as pest resistance, excessive pesticide residues, soil compaction, microbial imbalance, and harm to natural enemies, seriously threatening agricultural product safety and the ecological environment. With the rapid development of green and organic agriculture, the market urgently needs plant-derived / medicinal herb-derived plant protection products that are highly efficient, broad-spectrum, residue-free, and do not induce resistance.

[0003] Existing traditional Chinese medicine insect repellents suffer from fundamental technical defects due to their traditional processing methods:

[0004] The formula is simple, the efficacy is narrow, and it lacks broad-spectrum efficacy.

[0005] Most products use only single Chinese medicinal herbs such as Sophora flavescens, Neem, and Derris fusiforme, which are only effective against a few pests and cannot simultaneously control multiple categories of pests such as piercing-sucking, chewing, mites, moths, and stem borers, thus limiting their application scope.

[0006] Without a synergistic mechanism, the insect-repellent effect is weak.

[0007] It has not formed a complex mechanism of action of "interference avoidance + respiratory paralysis + wax breaking and egg dissolution + nutritional stress resistance". Relying solely on simple repellency results in low mortality and short duration of effect, which cannot meet the actual needs in the field.

[0008] Traditional extraction processes are outdated and result in significant loss of active ingredients.

[0009] Methods such as high-temperature boiling, alcohol extraction, and soaking are used, which involve high temperatures and long times, resulting in the destruction of a large number of heat-sensitive active ingredients such as volatile oils, medicinal alkaloids, terpenes, and flavonoids, leading to low extraction efficiency and poor efficacy.

[0010] Physical-biological coupling enhancement process

[0011] Simple extraction without modern technologies such as ultrasonic cell disruption, enzymatic hydrolysis, low-temperature concentration, and precise filtration results in low content of effective ingredients, poor permeability, poor spreadability, and low absorption and utilization rate.

[0012] It has only one function: it prevents pests but does not provide nutrients or improve the soil.

[0013] Traditional Chinese medicine insecticides only focus on killing insects, without supplementing nutrition, enhancing crop resistance, or improving soil, and cannot achieve the integrated effect of "insect control + yield increase + quality improvement + disease resistance".

[0014] It easily develops drug resistance and lacks a mechanism to break resistance.

[0015] It lacks a multi-target mechanism of action, and long-term use may still lead to resistance; it lacks resistance-breaking technology that disrupts the epidermal wax layer and interferes with the metabolic system, thus rendering it ineffective against pests in highly resistant areas.

[0016] Currently, none of the publicly disclosed patents and products have achieved a complete technical system that combines multi-target compound formulation, ultrasonic low-temperature directional extraction, bio-enzymatic hydrolysis for enhanced efficacy, and trace element chelation. This system cannot truly meet the needs of green agriculture for broad-spectrum, high-efficiency, residue-free, yield-increasing, and non-resistance-modifying plant protection formulations derived from Chinese medicinal herbs. Therefore, this paper proposes a broad-spectrum insect-repellent plant protection formulation derived from Chinese medicinal herbs and its ultrasonic extraction preparation method. Summary of the Invention

[0017] In view of this, the present invention provides a broad-spectrum insect-repellent plant protection preparation derived from traditional Chinese medicine and its ultrasonic extraction preparation method, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0018] The technical solution of this invention is achieved as follows: A broad-spectrum insect-repellent and plant protection preparation derived from traditional Chinese medicine, comprising, by weight:

[0019] 12-18 parts of neem bark, 8-12 parts of castor seeds, 8-12 parts of artemisia annua, 6-10 parts of neem, 6-10 parts of arborvitae leaves, 4-8 parts of honeysuckle, 4-8 parts of forsythia, 3-6 parts of scutellaria baicalensis, 3-6 parts of astragalus membranaceus, 2-5 parts of licorice, 0.3-0.8 parts of compound biological enzymes, 3-5 parts of amino acid solution, 0.5-1.2 parts of chelated trace elements, and deionized water to make up to 100 parts.

[0020] More preferably, the composite bioenzyme is a combination of cellulase and pectinase; the chelated trace elements are a Zn, B, and Mn composite chelate.

[0021] Further optimized versions feature a quadruple insect-repellent mechanism:

[0022] (1) The volatile oil interferes with the olfactory and gustatory senses of pests, producing a repulsive effect;

[0023] (2) Alkaloids and terpenoids in traditional Chinese medicine paralyze the respiratory and nervous systems of pests;

[0024] (3) The active ingredients dissolve the epidermal wax layer and eggshell, leading to dehydration and death;

[0025] (4) Inhibit the hatching of insect eggs and the development of larvae.

[0026] Further optimized strains exhibit highly effective control of aphids, whiteflies, thrips, spider mites, scale insects, cabbage caterpillars, diamondback moths, beet armyworms, rice stem borers, bean pod borers, and cotton bollworms, with a 24-hour corrected mortality rate ≥90%.

[0027] Further optimized formulations can inhibit insect egg hatching with an inhibition rate of ≥85%, a duration of effectiveness of 12–18 days, no pesticide residues, and are suitable for organic farming.

[0028] Further optimized varieties possess multiple functions, including insect prevention, egg breaking, seedling strengthening, leaf greening, fruit enlargement, yield increase, stress resistance, pesticide damage relief, pesticide residue reduction, and soil improvement.

[0029] A method for preparing a broad-spectrum insect-repellent plant protection agent derived from traditional Chinese medicine using ultrasonic extraction, comprising the following steps:

[0030] S1 raw materials are carefully selected, dried at low temperature, ultra-finely pulverized, and passed through a 40-60 mesh sieve;

[0031] S2 is added to the extraction tank, water is added at a material-to-liquid ratio of 1:8 to 1:12, compound biological enzymes are added, and the cell wall is broken by ultrasonication at 45 to 55°C and 20 to 40 kHz for 60 to 120 minutes.

[0032] S3 is enzymatic hydrolysis at constant temperature for 30-60 min, followed by enzyme inactivation at 85℃ for 10 min;

[0033] S4 three-stage filtration: plate and frame filtration → ultrafiltration membrane filtration → microfiltration;

[0034] S550~60℃ vacuum low-temperature concentration to 10~15% solids;

[0035] S640℃ or below, compound amino acid solution, chelated trace elements, pH adjusted to 5.5~7.5;

[0036] S7 is left to stand for 12-24 hours for aging, then filtered, filled, and the finished product is produced.

[0037] Further preferred embodiments include an ultrasonic power density of 0.8–1.2 W / cm², an enzymatic hydrolysis temperature of 45–50 °C, and a pH of 4.5–6.5.

[0038] Further optimized, the vacuum concentration process uses a vacuum level of -0.08 to -0.09 MPa, ensuring that the active ingredients are not damaged by the low temperature throughout the process.

[0039] Further optimized, it is suitable for crops such as fruit trees, vegetables, rice, cotton, tea, and Chinese medicinal herbs, and can be used safely during the seedling, flowering, and young fruit stages.
