Problems solved by technology

[0002] The disadvantages of chemical pesticide pest control are: increased residual toxicity, environmental pollution, and the killing of biological natural enemies, which pose a certain threat to humans and animals, destroy the balance of the biological phase, and make pests resistant to pesticides after continuous use. Therefore, biological pest control is more and more valued by scientific researchers.
[0004] Patent 201910215886.4 discloses a biological antibacterial and insect-resistant ecological system preparation and its preparation method and application. It is made by adding Chinese medicine, fruit and vegetable waste and vegetable waste to the filtrate mixture after fermentation with functional bacteria, and then adding carbonized organic matter, wood It is produced from vinegar, natural mineral elements, agricultural and chitosan oligosaccharides, agricultural grade trace elements, and plant extracts. It is a combination of microorganisms, organic active carriers, organic nutrition, trace element nutrition, and auxiliary pest control plant extracts. The ecological system preparation adapted to the growth of microorganisms can multiply rapidly around the rhizosphere after application to form dominant bacteria, thereby inhibiting bacteria and insects, resisting heavy cropping, stimulating crop growth, improving fertilizer utilization, crop yield and quality, but Its effect is: after the beneficial microorganisms are applied to the soil, they have high growth and reproduction ability, have the effect of insect and disease resistance on crop growth, increase safety, have no harmful substances, and improve the safety of agricultural products. Therefore, considering the effect of insect repellent preparations, the above-mentioned biological insect repellents have complex components, high cost of raw materials, and complicated and cumbersome production processes

preparation example Construction

[0027] A method for preparing a biological insecticide, said preparation method comprising the following steps:

[0028] S1. Prepare the raw materials and water according to the above ratio, soak the raw materials in clean water for 12 hours after crushing;

[0029] S2. Heating the water temperature in step S1 to 25±2°C;

[0030] S3. Put the EM.1 strain into the heat preservation fermenter.

[0031] Preferably, in step S3, the fermentation temperature in the heat preservation fermenter is 25-36° C., and the fermentation is for 5-7 days.

[0032] Preferably, the fermentation in step S3 is anaerobic fermentation.

[0033] The above fermentation process has mild conditions, simple steps, high production efficiency and low cost

[0034] The application of biological insecticides in the control of nematodes and pests that eat plant stems and leaves.

Embodiment 1

[0036] A kind of biological insect repellant, the raw material of biological insect repellent is neem bark, star anise, dried chili and fermented strains, fermented strains include yeast, lactic acid bacteria, photosynthetic bacteria and actinomycetes, every 100kg fermented liquid needs: neem bark 0.5kg , star anise 0.5kg, dried pepper 0.5kg, EM.1 strain 5kg.

Abstract

The invention relates to the technical field of insect-resist agents. The invention relates to an insect repellent, in particular to a biological insect repellent and a preparation method and application thereof. The biological insect-resist agent is prepared from the following raw materials: cortex meliae, star anise, dry red peppers and fermentation strains; the fermentation strains comprise saccharomycetes, lactic acid bacteria, photosynthetic bacteria and actinomycetes. 100 kg of fermentation liquor needs following raw materials: 0.5-0.8 kg of cortex meliae, 0.5-0.8 kg of star anise, 0.5-0.8 kg of dry red peppers and 5-6 kg of EM.1 strains; according to the biological insect-resist agent, the raw materials are simple and easy to obtain, and after the biological insect-resist agent is sprayed to leaf surfaces, metabolism of plants can be enhanced, protective film cuticles of the leaves are strengthened, and pathogenic bacteria are prevented from entering the leaves; in addition, theleavening agent contains an ester component, which is not decomposed in the body of the herbivorous insect and generates physiological barrier damage and is lethal; therefore, due to the action of stimulating substances such as capsaicine, the insect can feel uncomfortable and escape from the body, the insect preventing and expelling effect is obvious, and the preparation process is simple, convenient to use, low in production cost and suitable for industrial development.

Description

technical field [0001] The invention relates to the technical field of insect repellent, in particular to a biological insect repellent, a preparation method thereof and an application thereof. Background technique [0002] The disadvantages of chemical pesticide pest control are: increased residual toxicity, environmental pollution, and the killing of biological natural enemies, which pose a certain threat to humans and animals, destroy the balance of the biological phase, and make pests resistant to pesticides after continuous use. Therefore, biological pest control is more and more valued by scientific researchers. Biological pest control includes three methods: controlling pests with birds, controlling pests with insects, and controlling pests with fermented microbial preparations. [0003] Microbial preparations refer to products containing active microorganisms, which are used in agricultural production to provide special nutrients to crops, promote the metabolism of c...
