Problems solved by technology

[0004] The technical problem to be solved by the present invention: for the current use of chemical drugs to kill citrus psyllids and prevent citrus huanglongbing, although there is a certain effect, the drug effect time is short, and frequent spraying has not only increased the burden on fruit farmers, resulting in citrus psyllids. A large number of pesticides are resistant to pesticides, and the insecticidal effect is significantly reduced. The present invention provides a preparation method of a medicament for preventing and treating citrus Huanglongbing

preparation example Construction

[0022] A preparation method of a medicament for preventing and treating citrus huanglongbing, the preparation method comprising the following steps:

[0023] (1) In terms of parts by weight, take 80-90 parts of citrus buds, 30-40 parts of phoenix buds, 20-25 parts of citrus peels, 10-15 parts of neem seeds and 6-9 parts of mint, and put them into a blender Stir, dry at 60°C for 50 minutes, grind at 600r / min for 30 minutes, and collect the ground material;

[0024] (2) Mix the ground material and glucose solution evenly at a mass ratio of 1:3~5, put it into a fermenter, then add 6-8% of the ground material into the bacteria powder, and ferment at 30-38°C for 1-2 After 2 days, collect the fermentation mixture and carry out steam explosion. The steam explosion conditions are temperature 120-125°C, pressure 1.6-2.0MPa, maintaining pressure for 1-3 minutes, and collecting explosives;

[0025] (3) Put the explosives, edible fly maggots and ethanol solution in a ball mill at a mass ...

Embodiment 1

[0030] Choice of fungal powder: Aspergillus oryzae fungal powder.

[0031] The mixture is prepared by mixing zein, sodium alginate and 0.2 mol / L sodium phosphate uniformly at a mass ratio of 1:2:7 to obtain the mixture.

[0032] The choice of essential oil is marigold essential oil.

Grind at 600r / min for 30min, and collect the ground material;

[0035] (2) Mix the milled material and glucose solution evenly at a mass ratio of 1:5, put it into a fermenter, add 8% of the milled material to the bacteria powder, and ferment at 38°C for 2 days, collect the fermentation mixture, and carry out ...

Embodiment 2

[0041] Choice of bacteria powder: Aspergillus oryzae powder.

[0042] The mixed liquid is mixed evenly with zein, sodium alginate and 0.2mol / L sodium phosphate according to the mass ratio of 1:2:6 to obtain the mixed liquid.

[0043] The choice of essential oil is garlic essential oil.

[0044] A preparation method of a medicament for preventing and treating citrus huanglongbing, the preparation method comprising the following steps:

[0045] (1) In terms of parts by weight, take 85 parts of citrus buds, 35 parts of phoenix buds, 23 parts of citrus peels, 13 parts of neem seeds and 8 parts of mint, put them into a mixer for stirring, and dry them at 60°C for 50 minutes. Grind at 600r / min for 30min, and collect the ground material;

[0046] (2) Mix the milled product and glucose solution evenly at a mass ratio of 1:4, put it into a fermenter, add bacteria powder with 7% of the milled product mass, ferment at 35°C for 2 days, collect the fermentation mixture, and carry out St...

Abstract

The invention belongs to the field of disease and insect pest control of agriculture and particularly relates to a method for preparing a pesticide for preventing and treating citrusyellowshoot. According to the method, firstly, citrus tender shoots and the like are subjected to extraction by using the habit of phylloxera, orange peels and herba menthae are added during extraction to attract the phylloxera, a lure solution contains Chinaberry seeds, the phylloxera are killed by the Chinaberry seeds after the phylloxera are lured, and the phylloxera are adhered by using stickiness of a mixed solution; the lure solution contains rich nutrients which can be absorbed and utilized by citrus; then, substances such as eggplant leaves are subjected to extraction, and substances in an extract are compounded with essential oil, so that the extract is diffused to attract natural enemies of the phylloxera, and the phylloxera are killed and prevented and treated; and the added essential oil plays arole in driving the phylloxera. According to the method, the problem in the current killing of citrus phylloxera by using chemical pesticides that the pesticide effect time is short, the generation of pesticide resistance of the citrus phylloxera to a large number of pesticides is easily caused, and the pesticidal effect is obviously lowered is avoided, and the method is safe and is free of harm.

Description

technical field [0001] The invention belongs to the field of prevention and control of agricultural diseases and insect pests, and in particular relates to a preparation method of a medicament for preventing and treating citrus huanglongbing. Background technique [0002] my country is a big citrus producing country in the world. The citrus industry is the pillar industry of my country's agriculture, occupies an extremely important position in the agricultural economy, and plays an extremely important role in increasing farmers' income, increasing social employment and building a new socialist countryside. Citrus pests and diseases are major obstacles to the development of the citrus industry, the most serious of which is citrus huanglongbing, known as the "cancer" of citrus. With the rapid development of citrus production, the occurrence and damage of citrus huanglongbing are becoming more and more serious. The disease is a very harmful infectious disease. The pathogen is ...
