Embodiment 1

[0021] In May 2014, 50 citrus trees were selected from the Dafeng Citrus Farm in Guangzhou for testing for Huanglongbing. The results showed that the incidence rate of Huanglongbing was 100%. The experimental design followed the principle of random selection, randomly selected 10 plants as the treatment group, and adopted the trunk infusion method to input medicines (ampicillin sodium 10g, ammonium nitrate 0.2g, potassium dihydrogen phosphate 0.2g, magnesium sulfate 0.006g, EDDHA-Fe0.01g , EDTA-Mn0.005g, EDTA-Zn0.002g, EDTA-Cu0.002g, EDTA-Co0.00005g, EDTA-Ca0.002g, borax 0.001g, sodium molybdate 0.002g, trehalose 0.0005g, potassium fulvic acid 0.0005g, stabilizer: 1,2-butanediol 5mL; antifreeze agent: ethylene glycol, 10mL; new penetration aid: azone, 10mL; dispersant: sodium lignosulfonate, 10g; emulsifier: ten Sodium dialkylbenzene sulfonate, 10 grams; co-solvent: DMSO, 10 mL, adjust the pH value to 6.5, and dissolve into water to 1000 ml of the pharmaceutical composition), ...

Embodiment 2

[0034] In April 2014, 40 citrus trees were selected from the Zhongluotan Citrus Field in Baiyun District, Guangzhou, and tested for Huanglongbing. The results showed that the incidence rate of Huanglongbing was 100%. The experimental design followed the principle of random selection, randomly selected 10 plants as the treatment group, and adopted the trunk infusion method to input medicines (ampicillin sodium 8g, ammonium nitrate 0.15g, potassium dihydrogen phosphate 0.15g, magnesium sulfate 0.005g, EDDHA-Fe0.01g , EDTA-Mn0.005g, EDTA-Zn0.002g, EDTA-Cu0.002g, EDTA-Co0.00005g, EDTA-Ca0.002g, borax 0.001g, sodium molybdate 0.002g, trehalose 0.0005g, potassium fulvic acid 0.0005g, stabilizer: 1,2-butanediol 5mL; antifreeze agent: ethylene glycol, 0mL; new penetration aid: azone, 10mL; dispersant: sodium lignosulfonate, 10g; emulsifier: ten Sodium dialkylbenzene sulfonate, 10 grams; co-solvent: DMSO, 10 mL, adjust the pH value to 6.5, and dissolve into water to 1000 ml of the phar...

Embodiment 3

[0047] In June 2014, 60 citrus trees were selected from the Jilongshan Citrus Farm in Guangzhou for testing for Huanglongbing. The results showed that the incidence rate of Huanglongbing was 100%. The experimental design followed the principle of random selection, randomly selected 10 plants as the treatment group, and adopted the trunk infusion method to input medicines (ampicillin sodium 10g, ammonium nitrate 0.2g, potassium dihydrogen phosphate 0.2g, magnesium sulfate 0.006g, EDDHA-Fe0.01g , EDTA-Mn0.005g, EDTA-Zn0.002g, EDTA-Cu0.002g, EDTA-Co0.00005g, EDT-Ca0.002g, borax 0.001g, sodium molybdate 0.002g, trehalose 0.0005g, potassium fulvic acid 0.0005g, stabilizer: 1,2-butanediol 5mL; antifreeze agent: ethylene glycol, 2mL; new penetration aid: azone, 10mL; dispersant: sodium lignosulfonate, 10g; emulsifier: ten Sodium dialkylbenzene sulfonate, 10 grams; co-solvent: DMSO, 10 mL, adjust the pH value to 6.5, and dissolve into water to 1000 ml of the pharmaceutical composition...

Abstract

The invention provides a bactericide compound for preventing and treating candidatus liberibacter and a preparation method thereof. The bactericide compound is a compound composition prepared from antibiotics, ammonium nitrate, monopotassium phosphate, magnesium sulfate, EDDHA-Fr, EDTA-Mn, EDTA-Zn, EDTA-Cu, EDTA-Co, EDTA-Ca, borax, sodium molybdate, trehalose, potassium fulvic acid, a stabilizing agent, an antifreezing agent, novel permeation promoter, a dispersing agent, an emulsifying agent and co-solvent, the pH value is regulated to 6.5, and 1000-2000ml of water is added. The composition is reasonably mixed by bactericide and multiple nutritional substances according to objective requirement of prevention and control of candidatus liberibacter, is applied by adopting a trunk transfusion method to complement advantages, has the characteristics of high efficiency, low toxicity, safety and multiple functions, and can be used for better preventing and controlling candidatus liberibacter.

Description

technical field [0001] The invention belongs to the field of biological control, and in particular relates to a fungicide compound for preventing and treating Huanglongbing and a preparation method thereof. Background technique [0002] Citrus huanglongbing is the most harmful and devastating disease in citrus production, with annual economic losses reaching billions of dollars, which seriously restricts the development of citrus industry in China. [0003] There are currently no Huanglongbing resistant varieties available. At present, the prevention and control of Huanglongbing mainly depends on: 1. Strengthening the quarantine of seedlings, selecting disease-free seedlings and scions; 2. Excavating diseased trees. [0004] However, disease-free seedlings are not resistant to Huanglongbing disease, so it is still difficult to avoid being attacked by Huanglongbing disease after a period of time; although digging or cutting down diseased trees can limit the spread of the dis...
