Embodiment 1

[0015] Prescription: 0.5 parts of avermycin, 5 parts of tomato leaves, 5 parts of trichosanthemi, 10 parts of astragalus, 5 parts of pyrethrum, 10 parts of rehmannia glutinosa, 60 parts of soybean oil, and 0.1 part of emulsifier.

[0016] The preparation method of the above-mentioned yeast containing lycopene biopesticide comprises the following steps:

[0017] (1) (1) Wash the tomato leaves, trichosanthum pollen, astragalus, pyrethrum, and rehmannia glutinosa, add 6 times the volume of pure water, decoct twice for 2 hours each time, combine the extracts, and when concentrated to 30°C, the relative density is 1.05, refrigerated overnight at 4°C, filtered to obtain the filtrate;

[0018] (2) Mixing soybean oil, avermycin and an emulsifier to obtain an oil phase solution;

[0019] (3) Slowly add the above oil phase solution into the above filtrate, stir while adding, and finally stir for 20 minutes to obtain the product.

Embodiment 2

[0021] 0.5 parts of avermycin, 15 parts of tomato leaves, 15 parts of trichosanthemi, 20 parts of astragalus, 25 parts of pyrethrum, 25 parts of rehmannia glutinosa, 100 parts of soybean oil, and 0.5 parts of emulsifier.

[0022] The preparation method of the above-mentioned yeast containing lycopene biopesticide comprises the following steps:

[0023] (1) (1) Wash the tomato leaves, trichosanthum pollen, astragalus, pyrethrum, and rehmannia glutinosa, add 8 times the volume of pure water, decoct 3 times, each time for 4 hours, combine the extracts, and concentrate to 30 °C when the relative density is 1.10, refrigerated overnight at 4°C, filtered to obtain the filtrate;

[0024] (2) Mixing soybean oil, avermycin and an emulsifier to obtain an oil phase solution;

[0025] (3) Slowly add the above oil phase solution into the above filtrate, stir while adding, and finally stir for 40 minutes to obtain the product.

Embodiment 3

[0027] 0.5 parts of avermycin, 10 parts of tomato leaves, 10 parts of trichosanthes, 15 parts of astragalus, 15 parts of pyrethrum, 18 parts of rehmannia glutinosa, 80 parts of soybean oil, and 0.3 parts of emulsifier.

[0028] The preparation method of the above-mentioned yeast containing lycopene biopesticide comprises the following steps:

[0029] (1) (1) Wash the tomato leaves, trichosanthum pollen, astragalus, pyrethrum, and rehmannia glutinosa, add 7 times the volume of pure water, decoct twice for 3 hours each time, combine the extracts, and when concentrated to 30°C, the relative density is 1.08, refrigerated overnight at 4°C, filtered to obtain the filtrate;

[0030] (2) Mixing soybean oil, avermycin and an emulsifier to obtain an oil phase solution;

[0031] (3) Slowly add the above oil phase solution into the above filtrate, stir while adding, and finally stir for 30 minutes to obtain the product.

Abstract

The invention provides a biological insecticide containing lycopene and a preparation method of the biological insecticide. The biological insecticide is mainly prepared from components in parts by weight as follows: 0.5 parts of avilamycin, 5-15 parts of tomato leaves, 5-15 parts of snakegourd roots, 10-20 parts of radix astragali, 5-25 parts of pyrethrum, 10-25 parts of radix rehmanniae, 60-100 parts of soybean oil and 0.1-0.5 part of an emulsifier. Compared with an ordinary chemical pesticide in the prior art, the biological insecticide containing lycopene has the characteristics of good effect and low toxicity and can be used as an ideal environment-friendly agricultural plant protection drug; meanwhile, two or more pesticides are compounded, so that on one hand, the bactericidal and insecticidal spectrum can be widened, and on the other hand, the pesticide effect can be improved; and more importantly, the problem of drug resistance due to the fact that a single pesticide is used for a long term can be solved.

Description

technical field [0001] The invention relates to a biopesticide, in particular to a biopesticide mainly made of various traditional Chinese medicine extracts, which is applied in the field of agriculture. Background technique [0002] Biopesticides refer to living organisms and their metabolites and genetically modified products used to prevent and control harmful organisms such as diseases, insects, and grasses, and can be made into commercial biological source preparations, including bacteria, viruses, fungi, nematodes, plants, natural enemies of insects, Agricultural antibiotics, plant growth regulators and transgenic plants resistant to diseases, insect pests and weeds, etc. Biological pesticides have been used in agricultural production for half a century, but the development has been relatively slow due to various reasons. In recent years, people pay more and more attention to the sustainable development of agricultural production and the coordination between human and...
