Method for radically treating citrus candidatus liberobacter

Abstract

The invention discloses a method for radically treating citrus candidatus liberobacter. A solution for radically treating the citrus candidatus liberobacter is prepared and loaded in a suitable container, a needle tube of an injection syringe for trees is connected with the container, a needle is inserted into the rhizome of a citrus tree or the main root close to the ground surface, a liquid drainage hole in the syringe for the trees reaches the phloem and the xylem, and the solution for radically treating the citrus candidatus liberobacter is injected through the syringe for trees, wherein the solution for radically treating the citrus candidatus liberobacter contains any one or two of bactericidal solutions, one or more of diaphorina citri killing solutions and one or more of tree vigorimprovement solutions. The method for radically treating the citrus candidatus liberobacter has the advantages that the prevention and control of bacteria of the citrus candidatus liberobacter, the prevention and control of the diaphorina citri and the improvement of the tree vigor of diseased trees are organically combined, integrated prevention and control are conducted, and the effect is obvious.

Description

technical field [0001] The invention relates to prevention and control of forestry diseases and insect pests, in particular to a radical cure method for citrus huanglongbing. Background technique [0002] Citrus huanglongbing is a devastating disease and a worldwide problem. It is rampant in nearly 50 countries and regions in Asia, Europe, Africa, Australia, Oceania, South America and North America. The disease was discovered in Florida, the main citrus producing area of ​​the United States in 2005. Since 2006, it has caused a loss of 3.6 billion US dollars in the state. In my country, the disease has a history of nearly a hundred years. Since the 1970s, the disease has destroyed more than 1 million mu of citrus orchards in Guangxi, and the direct economic loss has exceeded 10 billion yuan. At least 100 million sick trees were felled in southern Jiangxi due to Huanglongbing disease. From 2010 to 2015, nearly 100 million citrus trees were infected with disease in my country...

AI Technical Summary

Problems solved by technology

Because the pathogens live in the phloem, it is difficult to spray pesticides on the leaves, and the sprayed medicinal liquid will also pollute the environment; in addition, citrus psyllids often occur with the new shoots of citrus trees, and the spraying is only effective on the existing shoots of citrus trees. The psyllids that occur when new shoots grow have an effect, but have little effect on the psyllids that occur when new shoots grow after spraying. Even the best medicine uses the foliar spray method, and the utilization rate of pesticides is limited, so it is impossible to do without Therefore, it is difficult to completely kill the citrus psyllids that spread the germs; some control experiments have been carried out by injecting needles on the trunk and injecting medicine on the tree trunk with multiple syringes at the same time, but all of them are due to the inappropriate concentration of the pesticides. , Insufficient amount of liquid medicine, inappropriate injection location and other problems, no obvious effect has been achieved; so far, once the citrus plants are infected by the pathogen, they can only be cut off to prevent the spread of the disease
