Functional components of cymbopogon distans volatile oil and application thereof

Abstract

The invention provides application of cymbopogon distans volatile oil in inhibition of phytopathogens or preparation of a botanical bactericide, wherein the phytopathogens are aspergillus flavus, rhizopus oryzae, mucor racemosus, trichoderma viride, lentil acanthomonas, fusarium oxysporum and / or potato late blight bacteria. Activity inhibition experiments prove that the cymbopogon distans volatileoil has high inhibition rate on rhizopus oryzae, mucor racemosus, trichoderma viride and lentil acanthomonas. In addition, the applicant also respectively tests the inhibition activity of main chemical components in the cymbopogon distans plant on the seven fungi, the result shows that the same compound shows different degrees of inhibition effects on different pathogenic bacteria and different inhibition effects on different compounds of the same pathogenic bacteria, and part of the compounds show an obvious inhibition effect, so that the cymbopogon distans volatile oil and the main chemicalcomponents can be used as botanical bactericides with great prospects.

Description

technical field [0001] The present invention relates to the active components of rue volatile oil and application thereof, in particular to the application of rue volatile oil in inhibiting plant pathogenic bacteria. Background technique [0002] In the planting industry of my country's edible fungi, it is the sixth largest product after grain, cotton, oil, fruit, and vegetables. It is a pillar industry and a dominant industry in agriculture and rural economy. Some miscellaneous bacteria caused a decrease in production, and some miscellaneous bacteria produced toxins, which caused our country to encounter a crisis in import and export. Common fungal miscellaneous bacteria in the reagent generation of edible fungi mainly include: Trichoderma viride, Neurospora, Mucor, Aspergillus, Rhizopus niger, yeast and so on. Most of these miscellaneous bacteria grow rapidly, and if the prevention is not timely, the quality of edible fungi will be seriously affected. Although chemically ...

Problems solved by technology

Most of these miscellaneous bacteria grow rapidly, and if the prevention is not timely, the quality of edible fungi will be seriously affected

Although chemically synthesized drugs to kill plant pathogenic fungi play an irreplaceable role in the prevention and control of plant diseases, people pay more and more attention to the toxicity of pesticides and the pollution of pesticides to the environment. Some bactericidal drugs with high toxicity and long residue Drug varieties, such as organochloromercury preparations (aldrin, 666), etc. have been banned in succession
