Embodiment Construction

[0055] Weigh 40-50 parts of three needles, 1-2 parts of Phellodendron cortex, 45-50 parts of perilla and 2-3 parts of castor in parts by weight, crush and extract respectively.

[0056] The extraction process is as follows: soak in clean water for 12 to 24 hours, the amount of clean water added is based on the amount of the medicinal material, stir 2 to 3 times during soaking, then heat to 90°C to 100°C, and keep in a slightly boiling state for 0.5 to 1 hour. Squeeze and filter, and the filtrate is centrifuged or placed to settle. Soak the filtered medicinal residues in clear water for 3-4 hours, boil for 1 hour and then filter, mix the two filtered liquids evenly, and concentrate the filtrate in low-temperature vacuum until each milliliter of medicinal liquid is equivalent to 1g of crude drug.

[0057] The extracted four kinds of plant extracts are mixed, and the auxiliary agent JFC9 or sodium dodecylbenzenesulfonate is added at a ratio of 1:0.5-1.5 to obtain the berberine bo...

Abstract

The invention relates to a berberine plant source insecticide and a preparation method thereof. The insecticide comprises the following raw materials in parts by weight: 40-50 parts of berberis root, 1-2 parts of phellodendron bark, 45-50 parts of purple common perilla and 2-3 parts of castor. The berberine plant source insecticide takes berberine in the berberis root and phellodendron bark as the insecticidal active component; and since berberine has photoactive toxicity for pests, and the toxicity of the berberine plant extract for pests is enhanced when the berberine plant extract is degraded under the activation of light, the invention enhances the drug effect of insecticide, prevents enduring residence in the environment and conforms to environment concordance required by no-pollution pesticides. The product of the invention has the advantages of no toxicity, no residue, wide materials sources and low production cost, has the effects of anesthetization, contact killing, stomach toxicity, systemic action and the like, has favorable integrated control effects of disinsection and bacteriostasis, can be widely used in the fields of agriculture, forestry, animal husbandry and the like, and is especially suitable for production of traditional Chinese medicinal materials, organic food, green food and no-pollution food.

Description

technical field [0001] The invention belongs to the technical field of pesticide production, and in particular relates to a berberine botanical pesticide and a preparation method thereof. Background technique [0002] Chemical pesticides have always played a dominant role in pest control due to their advantages of quick effect and strong knockdown power. At the same time, it also brings serious side effects, the ecological balance is destroyed, the environment is seriously polluted, pesticide residues endanger human health, diseases and insect pests generally develop drug resistance, and prevention and control are becoming more and more difficult. With the development of social productivity and the improvement of people's living standards, people are increasingly aware of the importance of environmental protection, especially pesticide residues are especially concerned by governments and consumers. Therefore, the pollution-free botanical pesticides with high efficiency and ...
