Description

Technical Field

[0001] The present invention relates to the technical field of agriculture and pest control, and in particular to a natural insect-proof plant composition and application thereof. Background Art

[0002] With the rapid development of modern agriculture, the use of chemical pesticides in agricultural production has become increasingly common. While these chemical pesticides can effectively control crop diseases and pests, their widespread use also brings with it numerous problems. While existing chemical pesticides can improve crop yield and quality in the short term, long-term reliance on chemical pesticides can have potential negative impacts on the environment, soil, crops, and human health, primarily in the following areas: Pesticide residue problem Chemical pesticide residues on crop surfaces and in the soil. Long-term use not only pollutes the environment but also poses a threat to human health through the food chain. The accumulation of pesticide residues can affect food safety, particularly posing potential risks to human and animal health. Even with strict control over pesticide dosage, residues can exceed standards, leading to consumers consuming agricultural products containing excessive pesticides, posing health risks.

[0003] Drug resistance problem Long-term, single-use chemical pesticides can lead to pest resistance. This, in particular, reduces the effectiveness of existing chemical pesticides in combating resistant pests, forcing farmers to constantly increase their pesticide usage or switch pesticide types. This not only increases farmers' production costs but also exacerbates environmental pollution and further impacts the healthy growth of crops.

[0004] Environmental pollution issues During use, chemical pesticides can be dispersed by wind or flow through rainwater into groundwater, rivers, and other water bodies, causing water pollution. Once pesticides enter water bodies, they can have long-term impacts on aquatic life and surrounding ecosystems, even disrupting the ecological balance of the water body. Furthermore, pesticides can contaminate soil, affecting microbial communities and soil health, thereby impacting crop growth and the sustainable development of the ecological environment.

[0005] Hazards to non-target organisms Chemical pesticides not only kill pests but also often harm other non-target organisms, including bees and natural enemy insects. These organisms are crucial to ecosystem biodiversity and agricultural production. Reducing the harm of chemical pesticides to non-target organisms has become a critical issue in modern agricultural production.

[0006] Workforce health issues During pesticide use, agricultural workers are exposed to pesticides for long periods of time, putting them at risk of pesticide poisoning or chronic poisoning. Both pesticide applicators and agricultural workers can be poisoned due to inadequate protective measures and improper operation, potentially affecting their health.

[0007] Therefore, a new solution to the above problems needs to be proposed. Summary of the Invention

[0008] The purpose of the present invention is to provide a natural insect-proof plant composition and application thereof, so as to solve the technical problems raised in the background technology.

[0009] To achieve the above object, the present invention provides the following technical solution: a natural insect repellent plant composition comprising astragalus polysaccharide, linalool, cinnamaldehyde, pomegranate peel polyphenols and water; Astragalus polysaccharide is extracted using a nano-scale extraction process. It can enhance plant immunity, promote plant growth, and improve crop resistance to diseases and pests. It can also effectively reduce pesticide residues, meeting the requirements of green agricultural production. Linalool has a synergistic effect, can enhance the efficacy of pesticides, reduce the amount of pesticides used, and has a good synergistic effect on the prevention and control of pesticide-resistant aphids, psyllids and whiteflies. It can improve the penetration of the pesticide solution and increase the adhesion of the pesticide solution on the plant surface; The cinnamaldehyde is a natural agricultural synergistic adjuvant with a good insect repellent effect. It can improve the efficacy of insecticides and is used to control lepidopteran pests such as diamondback moth, cotton bollworm and thrips. It can also enhance the penetration of the liquid medicine and help the medicine enter the plant better. The pomegranate peel polyphenol has an insect repellent effect, especially against mites and red spiders. The pomegranate peel polyphenol can effectively improve the effect of the insecticide while increasing the penetration of the liquid medicine and reduce the generation of insecticide-resistant pests.

[0010] Furthermore, the ratio of astragalus polysaccharide in the composition is 5%-15%; The proportion of linalool is 2%-8%; The proportion of the cinnamaldehyde is 3%-10%; The proportion of the pomegranate peel polyphenols is 4%-12%.

[0011] The invention discloses an application of a natural insect-proof plant composition, which is used to dilute and spray crops and flower crops to kill insects and reduce pesticide residues. The crops include at least vegetable crops, fruit tree crops, rice and berry crops.

[0012] Furthermore, the process of spraying after dilution includes at least the following steps: Dilute according to the spraying needs of the crop; Spray the diluted liquid medicine evenly on the back and front of the crop leaves, ensuring that both sides are fully covered and evenly penetrated.

[0013] Furthermore, the dilution ratio is 300-2000.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a natural insect-proof plant composition, which combines multiple natural plant-derived active ingredients, can effectively prevent and control multiple agricultural pests, especially pesticide-resistant pests, has a good synergistic effect, can effectively improve the efficacy of insecticides, and at the same time reduce the use of chemical pesticides, thereby achieving green ecological planting; the main components of the composition include astragalus polysaccharide, linalool, cinnamaldehyde and pomegranate peel polyphenols; through reasonable proportions and scientific extraction technology, the composition has strong penetration and adhesion, thereby achieving an ideal insect-proof effect.
