Problems solved by technology

The thoroughness of the removal of Huanglongbing trees has a great impact on the prevention and control of Huanglongbing. At present, most of the orchards are scattered and planted in a state of extensive management. It is basically impossible for young and middle-aged laborers to go out to work, and it is basically impossible to dig up diseased trees in a large area, which affects the removal of Huanglong diseased trees.

Embodiment 1

[0028] A medicament for preventing and treating citrus huanglongbing mainly consists of the following components and parts by weight: 75 parts of eucalyptus-containing extract; 20 parts of ampicillin; 0.5 parts of rhodamine B; 4.5 parts of fast penetrating agent T.

[0029] Its preparation method is as follows:

[0030] ① Weigh 200g of eucalyptus myrtaceae leaves (calculated by absolute dry weight), directly soak and boil them in 1800mL of water for 25min, filter and remove the eucalyptus leaves to obtain a eucalyptin-containing extract.

[0031] ②Weigh 750g of the eucalyptus-containing extract prepared in step ① and heat it to 75°C, then slowly add it to 200g of ampicillin, then add 5g of rhodamine basic B and 45g of rapid penetrant T, and stir well to obtain orange Drugs for the prevention and treatment of orange dragon disease.

Embodiment 2

[0033] A citrus huanglongbing prevention and control agent mainly consists of the following components and parts by weight: 93 parts of eucalyptus extract; 2 parts of ampicillin; 0.4 parts of rhodamine B; 4.6 parts of fast penetrating agent T.

[0034] Its preparation method is as follows:

[0035] ①Weigh 200g of eucalyptus myrtaceae leaves (calculated by absolute dry weight), directly soak and boil them in 1600mL of water for 20min, filter and remove the eucalyptus leaves to obtain a eucalyptin-containing extract.

[0036] ②Weigh 930g of the eucalyptus-containing extract prepared in step ① and heat it to 70°C, then slowly add it to 20g of ampicillin, then add 4g of rhodamine basic B and 46g of rapid penetrant T, and stir well to obtain the orange Drugs for the prevention and treatment of orange dragon disease.

Embodiment 3

[0038] A medicament for preventing and treating citrus huanglongbing mainly consists of the following components and parts by weight: 45 parts of eucalyptus-containing extract; 50 parts of ampicillin; 0.6 parts of rhodamine B; and 4.4 parts of high-efficiency penetrant.

[0039] Its preparation method is as follows:

[0040] ①Weigh 100g of eucalyptus myrtaceae leaves (calculated by absolute dry weight), directly soak and boil them in 1000mL of water for 30min, filter and remove the eucalyptus leaves to obtain a eucalyptin-containing extract.

[0041] ②Weigh 450g of the eucalyptus-containing extract obtained in step ① and heat it to 60°C, then slowly add it to 500g of ampicillin, then add 6g of rhodamine B and 44g of high-efficiency penetrant, and stir well to obtain citrus Drugs for the prevention and treatment of Huanglongbing.

Abstract

The invention discloses a reagent for preventing and treating citrus huanglongbing and a preparation method thereof. The reagent is mainly prepared from the following components in parts by weight: 45-93 parts of an eudesmin-contained extracting solution, 2-50 parts of ampicillin, 0.4-0.6 part of a color developing agent and 4.4-4.6 parts of a penetrating agent. The method comprises the followingsteps that the eudesmin-contained extracting solution is weighed according to the weight parts, is heated to 60-75 DEG C and then is slowly added into the ampicillin, then the color developing agent and the penetrating agent are added, and full and uniform mixing is carried out so as to obtain the reagent for preventing and treating the citrus huanglongbing. The reagent has the advantages that pathogenic bacteria of the citrus huanglongbing can be effectively killed in time, a tree body is enabled to generate an antibody and is no longer afraid of plant-louse-borne pathogenic bacteria, and thedamage of the citrus huanglongbing can be completely controlled.

Description

technical field [0001] The invention belongs to the technical field of fruit tree prevention and control, and in particular relates to a citrus huanglongbing prevention and control agent and a preparation method thereof. Background technique [0002] Citrus huanglongbing (citrus huanglongbing) is the most dangerous infectious disease that harms citrus production. It is considered to be a devastating disease in citrus production and can occur throughout the growing season of citrus. After the citrus trees are infected by Huanglongbing, the tree vigor will decline, the yield will drop by 20-30%, and the fruit quality will decline; in severe cases, the diseased plants will die within 3-5 years, and a flourishing citrus orchard infected with Huanglongbing may die All destroyed in a few short years. In my country, the disease is currently distributed in Guangdong, Guangxi, Hainan, Fujian, Hunan, Guizhou, Yunnan, Sichuan, Chongqing, Jiangxi, Zhejiang, and Taiwan provinces, cities...
