Problems solved by technology

At present, the prevention and control of citrus Huanglongbing is mainly based on the cultivation of virus-free seedlings and antibiotics. Because they cannot really kill the bacteria effectively, these measures often have no obvious effect on diseased trees, and still cannot effectively prevent the occurrence of Huanglongbing. After several years of growth, Huanglongbing will break out again
Although considerable progress has been made in the research of HLB bacterial genomics and citrus pathology in recent years, and the interaction between pathogen and host has been well understood, it is still too early to discuss the topic of eradicating citrus HLB

Embodiment 1

[0024] A kind of medicine for preventing and treating citrus huanglongbing of the present invention is configured by the following parts by weight: 3 parts of aspirin, 0.3 part, 0.1 part of caffeine, 0.1 part of magnesium trisilicate, 22 parts of basic nutrients, wherein the basic nutrients are 2.5 parts of ammonium phosphate parts, potassium nitrate 15 parts, ammonium sulfate 1.5 parts, ammonium nitrate 1.5 parts, ferrous sulfate 0.1 parts.

[0025] The aspirin, caffeine and magnesium trisilicate are all powders, which are the core components of the medicine of the present invention. Aspirin is the main antibacterial agent, which can close the stomata of fruit tree leaves, reduce water evaporation, prevent crop diseases, reduce flower and fruit drop of crops, improve Crop quality and so on. However, aspirin used alone cannot prevent the occurrence of citrus huanglongbing very well, and the addition of caffeine can greatly enhance the efficacy of aspirin, because aspirin degra...

Embodiment 2

[0031] A kind of medicine for preventing and treating citrus huanglongbing of the present invention is configured by the following parts by weight: 5 parts of aspirin, 0.1 part of caffeine, 0.3 part of magnesium trisilicate, 17 parts of basic nutrients, wherein the basic nutrients are 1.7 parts of ammonium phosphate, nitric acid 10 parts of potassium, 2.0 parts of ammonium sulfate, 1.5 parts of ammonium nitrate, 0.3 parts of ferrous sulfate.

[0032] The preparation method of the above-mentioned medicine for preventing and treating citrus huanglongbing comprises the following steps:

[0033] 1) Take 1.7 parts of ammonium phosphate, 10 parts of potassium nitrate, 2.0 parts of ammonium sulfate, 1.5 parts of ammonium nitrate, 0.3 parts of ferrous sulfate in order, add 10000 parts of water, stir and dissolve to form a basic nutrient solution;

[0034] 2), then take aspirin, caffeine, and magnesium trisilicate powder according to the weight parts and mix them evenly, and add them i...

Embodiment 3

[0037] A kind of medicine for preventing and treating citrus Huanglongbing of the present invention is configured by the following parts by weight: 4 parts of aspirin, 0.2 part of caffeine, 0.2 part of magnesium trisilicate, 20 parts of basic nutrients, wherein the basic nutrients are 2.0 parts of ammonium phosphate, nitric acid 12 parts of potassium, 1.7 parts of ammonium sulfate, 1.7 parts of ammonium nitrate, 0.3 parts of ferrous sulfate.

[0038] The preparation method of the above-mentioned medicine for preventing and treating citrus huanglongbing comprises the following steps:

[0039] 1), take 2.0 parts of ammonium phosphate, 12 parts of potassium nitrate, 1.7 parts of ammonium sulfate, 1.7 parts of ammonium nitrate, 0.3 parts of ferrous sulfate in order, add 10000 parts of water and fully stir and dissolve to form a basic nutrient solution;

[0040] 2), then take aspirin, caffeine, and magnesium trisilicate powder according to the weight parts and mix them evenly, and ...

Abstract

The invention relates to a pesticide for controlling liberobacter asiaticum. The pesticide for controlling liberobacter asiaticum comprises, by weight, 3-5 parts of aspirin, 0.1-0.3 part of caffeine,0.1-0.3 part of antacid and 17-22 basic nutrients. The invention also provides a preparation method of the pesticide for controlling liberobacter asiaticum. The method includes the steps of forming abasic nutrient solution with the basic nutrients, and then adding powder aspirin, caffeine and antacid to form pesticide liquor. The pesticide is injected into diseased plants in an intravenous drip manner, the disease resistance is enhanced through the physiological accommodation of the diseased plants, the life of the diseased plants is prolonged, the bearing capacity is recovered, the citrus fruit quality is improved, the human and financial input for controlling liberobacter asiaticum of citrus trees can be reduced, and the pesticide has positive significance for the healthy development ofthe citrus fruit industry.

Description

technical field [0001] The invention relates to the field of agricultural plant protection, in particular to a medicine for preventing and treating citrus huanglongbing, a preparation method and a use method thereof. Background technique [0002] Citrus greening disease is a major citrus disease, commonly known as "citrus cancer". The pathogen of citrus greening disease is a Gram-negative bacterium that parasitizes in the phloem of citrus, and its vector is the citrus psyllid. When the citrus psyllid exists in the orchard, the pathogen spreads through the psyllid in a large number, so that more than 95% of the citrus are infested in less than three years, and the infected citrus shows shoots, yellow leaves, leaf spots and fruits. deformity and other diseases, causing a decline in its quality and yield traits. [0003] How to control citrus greening disease is a difficult problem that citrus researchers and growers must face at present and for a long time to come. Planting...
