Problems solved by technology

[0003] At present, 20% of azinamide is commonly used to prevent and control blueberry fruit stiffness, and the environmental pollution caused by the extensive use of chemical pesticides is becoming more and more serious
At the same time, when chemical pesticides and fungicides are used, various plant pathogenic bacteria will develop drug resistance and drug resistance, which will increase the difficulty of control and even cause control failure
In addition, chemical pesticides pose a threat to beneficial organisms because they are not selective
Moreover, many chemical pesticides are non-degradable or difficult to degrade, and are easy to accumulate in animals and plants, resulting in the enrichment of pollutants

Embodiment 1

[0021] A fungicide for preventing and treating blueberry fruit stasis is prepared from the following components in parts by weight: 7 parts of licorice, 6 parts of mugwort leaves, 6 parts of cassia seeds, 3 parts of castor leaves and 1 part of deervine.

[0022] Its preparation method comprises the following steps:

[0023] (1) Mix licorice, mugwort leaves, cassia seeds, castor leaves, and deer cane;

[0024] (2) Add the mixed material to 8 times the weight of water, heat and decoct for 3 hours;

[0025] (3) Filter, collect the filtrate, add the filter residue to 8 times the weight of water, heat and decoct for 2 hours;

[0026] (4) Filtrate, combine the filtrates, and concentrate to 1 / 15 of the total amount of water added to obtain the stock solution;

[0027] (5) Dry the filter residue and pulverize it into a medicinal powder.

Embodiment 2

[0029] A fungicide for preventing and treating blueberry fruit stasis is prepared from the following components in parts by weight: 6 parts of licorice, 8 parts of mugwort leaves, 4 parts of cassia seeds, 4 parts of castor leaves and 1 part of deervine.

[0030] Its preparation method comprises the following steps:

[0031] (1) Mix licorice, mugwort leaves, cassia seeds, castor leaves, and deer cane;

[0032] (2) Add the mixture to 10 times the weight of water, heat and decoct for 4 hours;

[0033] (3) Filter, collect the filtrate, add the filter residue to 10 times the weight of water, heat and decoct for 3 hours;

[0034] (4) filter, combine the filtrates, concentrate to 1 / 20 of the total amount of water added, and obtain the stock solution;

[0035] (5) Dry the filter residue and pulverize it into a medicinal powder.

Embodiment 3

[0037] A fungicide for preventing and treating blueberry fruit stasis is prepared from the following components in parts by weight: 8 parts of licorice, 4 parts of mugwort leaves, 8 parts of cassia seeds, 2 parts of castor leaves and 2 parts of deervine.

[0038] Its preparation method comprises the following steps:

[0039] (1) Mix licorice, mugwort leaves, cassia seeds, castor leaves, and deer cane;

[0040] (2) Add the mixture to 5 times the weight of water, heat and decoct for 1 hour;

[0041] (3) Filter, collect the filtrate, add the filter residue to 5 times the weight of water, heat and decoct for 1 hour;

[0042] (4) Filtrate, combine the filtrates, and concentrate to 1 / 10 of the total amount of water added to obtain the stock solution;

[0043] (5) Dry the filter residue and pulverize it into a medicinal powder.

[0044] Medication method: Store the prepared stock solution at 0-4°C; mix the stock solution with 50-100 times the amount of water when necessary, spray ...

Abstract

The invention discloses a preparation method of a bactericide for preventing and treating blueberry stiff fruit disease. The method comprises the steps that 6-8 parts of radix glycyrrhizae, 4-8 parts of folium artemisiae argyi, 4-8 parts of cassia seeds, 2-4 parts of castor leaves and 1-2 parts of derris are mixed; 5-10-fold water by weight is added, and heating and decoction are performed for 1-4 h; filtering is performed, a filtrate is collected, filter residues are added into 5-10-fold water by weight, and heating and decoction are performed for 1-3 h; filtering is performed, filtrates are combined, condensation is performed till the solution is 1 / 20-1 / 10 the total amount of the added water, and a stock solution; after being dried in the sun, the filter residues are smashed to form medicine powder; the stock solution is sprayed one to two times after being diluted before flowering of blueberries, and the medicine powder is sprayed to the periphery of the blueberry plants in August to September. The raw materials are abundant in source and low in cost; due to the adopted components, the bactericide is free of toxicity, and the blueberry stiff fruit disease can be effectively prevented and treated.

Description

technical field [0001] The invention belongs to the field of fruit tree disease prevention and control, and in particular relates to a fungicide for preventing and treating blueberry dead fruit disease and a preparation method thereof. Background technique [0002] Fruit stiffness is one of the most common and serious diseases in blueberry production. It is caused by fungi. In the early stage of invasion, mature spores germinate on the surface of new leaves and flowers, and hyphae develop inside and outside the cells on the surface of leaves and flowers, causing cell rupture and death. As a result, new leaves, buds, stems, inflorescences, etc. suddenly wilt and turn brown. After 3 to 4 weeks, the powder produced by the fungal spores covers the leaf veins, stem tips, and styles, and spreads to the open flowers for secondary infection. Finally, the affected fruits wilt, lose water, dry out, fall off, Zombie-like. After surviving the winter, the spores on the dead fruit ger...
