Problems solved by technology

[0004] At present, although there have been related studies on the insecticidal and antibacterial activities of the active substances in citrus, the application scope and methods of the active substances mentioned in these studies are still limited. At the same time, these studies have not explained what the antibacterial active substances contained in the extract are, so further research is necessary

Embodiment 1

[0017] A bacteriostatic pesticide composition, which is composed of limonene, linalool, β-pinene, α-terpineol, citral, myrcene and n-hexanal; the amount of each substance is respectively calculated in parts by weight 45.53 parts of limonene, 15.34 parts of linalool, 2.10 parts of β-pinene, 3.33 parts of α-terpineol, 4.13 parts of citral, 7.77 parts of myrcene, and 1.51 parts of n-hexanal.

[0018] In order to obtain the composition of the above bacteriostatic pesticide composition, the following investigations were also carried out in this example:

[0019] ①Wash the orange peel and dry it, dry it at 50℃, crush it and sieving, then add petroleum ether, absolute ethanol, acetone, ethyl acetate according to the material-to-liquid ratio of 12.5ml / g, and seal with plastic wrap at 50℃ Ultrasonic extraction for 40 minutes, filtration under reduced pressure, repeated three times, and then the collected filtrate was concentrated under reduced pressure to obtain an extract; ②The extraction ...

Abstract

The present invention relates to an antimicrobial pesticide composition. The composition comprises limonene, linalool, beta-pinene, alpha-terpineol, citral, myrcene, and hexanal. The invention not only provides a new way for development and utilization of active substances in citrus, but also provides a basis for the citrus active substances used in research and development of antimicrobial pesticides.

Description

Technical field [0001] The invention relates to the application of a pesticide composition in inhibiting pathogenic fungi, in particular to a bacteriostatic pesticide composition and its use. Background technique [0002] In recent years, scholars at home and abroad have done a lot of research work on the screening of bacteriostatic and insecticidal plant resources, and discovered many plant resources with bacteriostatic and insecticidal activity. For example, Wilson et al. screened out 13 kinds of plants and 4 kinds of essential oils from 345 kinds of plants and 49 kinds of essential oils with strong antibacterial activity. For another example, studies by Viuda-Marto found that the effects of four essential oils of lemon, citrus, grapefruit and navel orange on the growth of molds are usually related to food spoilage, and found that orange essential oil is the most effective against Aspergillus niger, while citrus essential oil can inhibit the growth of Aspergillus flavus. For g...
