Embodiment 1

[0019] Embodiment 1: the preparation of patchouli volatile oil

[0020] (1) Add 8 times the mass of water to 1000g of chopped patchouli, soak for 2 hours, and use steam to extract the volatile oil in patchouli by heating and distillation. ;

[0021] (2) The extracted fluid was dried with anhydrous sodium sulfate to remove the contained water to obtain the volatile oil of patchouli, which was put into a brown sample bottle, sealed, and stored at -20°C until use.

Embodiment 2

[0022] Embodiment 2: the activation of pathogenic bacteria

[0023] (1) Potato Dextrose Agar (PDA): 200g potato, 20g glucose, 20g agar, 1000mL distilled water;

[0024] (2) Purify and identify the pathogenic bacteria isolated from the roots and shoots of Panax notoginseng, and identify them as Fusarium solani, Pythium aphanidermatum, Cylindrocarpondestructans, Botrytis cinerea cinerea), Colletotrichum gloeosporioides and Rhizoctonia solani, the above strains were inoculated on PDA medium for activation, and after inoculation for 3 to 4 times, vigorously growing strains were taken for later use.

Embodiment 3

[0025] Embodiment 3: GC-MS measures the chemical composition of patchouli volatile oil

[0026] (1) GC conditions: Instrument model: Agilengt Technologies 7890B-5977B; Chromatographic column: HP-5MS30m×250μm×0.25μm;

[0027] (2) EI source ionization source temperature: 230°C; quadrupole temperature: 150°C; scanning range: 30-500m / z; inlet temperature: 285°C; split ratio 10:1; sample volume: 1μl; Energy: 70eV; temperature program of column oven: 50°C for 4min, 5°C / min to 120°C, 1°C / min to 180°C, 10°C / min to 280°C and hold for 16min; The retention time of the alkane continuous carbon (C9-C25) is calculated, and the retention time and mass spectrum of the compound are compared with the NIST17.L database to determine the final compound. The test results are shown in the table below;

Abstract

The invention discloses new uses of Pogostemon cablin volatile oil in agriculture, ie., applications in prevention and control of root rot of Chinese medicinal materials or crops, or applications in prevention and control of pathogenic bacteria causing the diseases of the aerial parts of Chinese medicinal materials or crops. According to the present invention, the experiment results show that the Pogostemon cablin volatile oil can strongly inhibit the hypha growth of three major pathogenic bacteria such as Fusarium solani, Pythium aphanidermatum and Cylindrocarpon destructans causing the root rot of Panax notoginseng, and three pathogenic bacteria such as Botrytis cinerea, Colletotrichum gloeosporioides and Rhizoctonia solani causing the diseases of the aerial part of Panax notoginseng; at a concentration of 50 mg / mL, the inhibition rates of the Pogostemon cablin volatile oil to three aerial part fungi are more than 80%; for the root fungi, the Pogostemon cablin volatile oil has the inhibition effect similar to the inhibition effect of hymexazol; and the Pogostemon cablin volatile oil is volatile, and has characteristic of aromatic decontamination, such that the fertilizer or pesticide developed from the Pogostemon cablin volatile oil has advantages of safety, effectiveness, low residue and the like.

Description

technical field [0001] The invention relates to the application of the volatile oil of patchouli, in particular to the control effect of the volatile oil of patchouli on root rot of Chinese medicinal materials or crops and various diseases of the aboveground parts of Chinese medicinal materials or crops, and belongs to the technical field of biopesticides. Background technique [0002] Sanqi (Panax notoginseng (Burk.) F.H.Chen) is a perennial herbaceous plant of the Araliaceae ginseng genus. Its leaves, leaves and flowers can be used as medicine, and the range of medicine is very wide. The social demand is constantly increasing. With the rapid increase of the planting area of ​​Panax notoginseng, its disease problem is becoming more and more serious, which has become the main obstacle to the production of Panax notoginseng. At present, the prevention and treatment of Panax notoginseng disease mainly relies on various chemical agents. Although chemical pesticides are effectiv...
