Description

Technical Field

[0001] The invention belongs to the technical field of pesticides, and in particular relates to a green insecticide for garden plants. Background Art

[0002] There are problems with pests and diseases in the planting process of garden plants. The pesticides generally used for pests and diseases are generally chemical preparations. After spraying, these pesticides will emit irritating and toxic gases, pollute the air, and also cause certain harm to the human body. Moreover, after direct application, the harmful residues are not easy to remove. Long-term consumption can cause various diseases in the human body (precocious puberty in children, endocrine disorders, organ dysfunction, fetal DNA damage, etc.) and even cancer.

[0003] Therefore, it is extremely necessary to study a green insecticide for garden plants and insecticides. Summary of the invention

[0004] The purpose of the present invention is to provide a green insecticide for garden plants.

[0005] The object of the present invention is achieved in that a green insect repellent for garden plants is composed of the following raw materials in parts by weight: 1 part of wolfsbane sulfur mixture, 0.03-0.05 parts of capsaicin, 0.1-0.5 parts of wind oil essence, 0.1-0.5 parts of oxytetracycline and 100-400 parts of water; The preparation method of the insect repellent and insecticide is to mix the raw materials evenly to obtain the insect repellent and insecticide.

[0006] The main component of the insecticide of the present invention is the extract of Chinese medicine wolfsbane, which has a strong effect of killing or inhibiting pests, and can also interfere with the synthesis of fungal cell walls, causing its structure to collapse, thereby destroying the life activities of fungi, and combining with sulfur to produce a series of complex reactions to generate complexes, producing substances that paralyze or destroy the brain nerves of pests, while being harmless to humans and animals, thereby achieving the purpose of eliminating pests and diseases on green plants. The capsaicin component can cause pests to have a strong stress response, and produce a strong resistance memory to the plants they have eaten, so that they will not eat the plants again; the wind oil component has a strong irritation to pests, and when pests approach and smell the odor, they will instinctively flee, achieving the effect of preventing pests; and the broad-spectrum antibiotic oxytetracycline has a killing and inhibitory effect on bacteria that invade the plant body.

[0007] The insecticide of the present invention is mainly composed of effective Chinese herbal medicines with insecticidal effects and an insect repellent and insect-proof compound with a strong and sensitive odor to pests, and has a certain anti-plant pathogenic bacteria effect, is non-toxic, harmless and non-irritating to the human body, is easy to clean, widely available and highly effective, will not cause pests to develop drug resistance, does not pollute the environment, and has easily available raw materials for easy preparation and low cost.

[0008] The insecticide of the present invention can be used to kill harmful insects such as aphids, mealybugs, red wax scale, pseudohorn scale, thrips, leafhoppers, moths, beetles, caterpillars, cutworms, pine caterpillars, tussock moths, and red fire ants. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0010] The present invention is further described in detail below in conjunction with the embodiments, but the present invention is not limited in any way. Any changes or improvements made based on the teachings of the present invention fall within the protection scope of the present invention.

[0011] The invention discloses a green insect repellent for garden plants, which is composed of the following raw materials in parts by weight: 1 part of wolfsbane sulfur mixture, 0.03-0.05 parts of capsaicin, 0.1-0.5 parts of wind oil essence, 0.1-0.5 parts of oxytetracycline and 100-400 parts of water; The preparation method of the insect repellent and insecticide is to mix the raw materials evenly to obtain the insect repellent and insecticide.

[0012] 0.1-0.5 parts of oxytetracycline are added to the insecticide to prevent and control plant diseases and insect pests.

[0013] The preparation method of the wolfsbane sulfur mixture is as follows: after washing and drying the dried Chinese medicine wolfsbane, water 20 times the mass of the wolfsbane is added to boil until 1 / 5-1 / 2 of the original volume is obtained to obtain an extract, the extract is filtered with gauze, sulfur and hot water greater than 50 degrees are added and stirred in a hot pot until the color of the extract becomes brown, wherein the mass ratio of the extract, sulfur and hot water is 1:2:10; finally, 1-51% of the mass of the extract is added with alcohol and stored in a dark plastic barrel to obtain the wolfsbane sulfur mixture for use.

[0014] The alcohol concentration is 75-95%.

[0015] Example 1 The preparation method of wolfsbane sulfur mixture is as follows: wash and dry the dried Chinese medicine wolfsbane, add 20 times the mass of water of wolfsbane and boil it until it reaches 1 / 5 of the original volume to obtain an extract, filter the extract with gauze, add 2 times the mass of sulfur and 10 times the mass of 60-degree hot water of the extract, stir in a hot pot until the boiled material becomes brown in color, finally add 21% 75% concentration of alcohol according to the mass of the boiled material, store it in a dark plastic barrel to obtain the antiseptic wolfsbane sulfur mixture.

[0016] Example 2 The preparation method of wolfsbane sulfur mixture is as follows: wash and dry the dried Chinese medicine wolfsbane, add 10 times the mass of water to boil until the volume reaches 1 / 3 of the original volume to obtain an extract, filter the extract with gauze, add 2 times the mass of sulfur and 10 times the mass of 80-degree hot water to stir in a hot pot until the boiled material becomes brown in color, finally add 51% of 90% concentration of alcohol according to the mass of the boiled material, store it in a dark plastic barrel to obtain a preservative wolfsbane sulfur mixture.

[0017] Example 3 The wolfsbane sulfur mixture prepared in Example 1, wind oil essence, industrial capsaicin, agricultural oxytetracycline (optional if sterilization is required) and water are mixed in a mass ratio of 1:0.03:0.1:1:100 to obtain an insecticide, and the insecticide is stored in a sealed light-proof container for later use.

[0018] When using, take out the amount according to the usage and add it directly to the sprayer and spray it on the green plants. After spraying once, observe the insecticidal effect the next day. If it is not completely killed, continue spraying. 10 kg of the agent can spray about 500 square meters of green plants, that is, about 20 grams per square meter.

[0019] Example 4 The wolfsbane sulfur mixture prepared in Example 1, wind oil essence, industrial capsaicin, agricultural oxytetracycline (optional if sterilization is required) and water are mixed in a mass ratio of 1:0.04:0.3:1.5:300 to obtain an insecticide, which is placed in a sealed light-proof container for storage and standby use. When used, it can be taken out according to the amount used and directly added to a sprayer and sprayed on green plants. This ratio is effective against medium-sized pests (for example: pseudohorn scale, thrips, leafhoppers, moths, scarabs, spur moths, cutworms, pine caterpillars, tussock moths, etc.).

[0020] Example 5 The wolfsbane sulfur mixture prepared in Example 1, wind oil essence, industrial capsaicin, agricultural oxytetracycline (optional if sterilization is required) and water are mixed in a mass ratio of 1:0.05:0.5:2:400 to obtain an insecticide, which is placed in a sealed light-proof container for storage and can be taken out according to the amount to be used and directly added to a sprayer for spraying on green plants. This ratio is effective against small pests such as aphids.

[0021] Test Example 1 Insecticide Effect Experiment of the Insecticide of the Present Insecticide 1. Test methods The test selected low-lying green plants in the community with serious pests and diseases and places where red fire ants were present. After the pests were found on site, mosquito larvae were placed in a large wide-mouth bottle, and the other pests (aphids, pine caterpillars, and red fire ants) were placed in a paper box. The insecticide prepared in Example 3-5 was sprayed once with the insects, and the start time of spraying was recorded. The insects' reactions and death time were carefully observed and recorded. The results are shown in Table 1.
