Description

technical field

[0001] The invention relates to the field of plant disease prevention and control, in particular to a composition for preventing and treating Huanglongbing and a preparation method thereof. Background technique

[0002] Huanglongbing is a disease that is extremely harmful to citrus production, and its pathogen is a Gram-negative bacterium that exclusively parasitizes in the phloem of citrus. The pathogenic bacteria of Huanglongbing spreads with the psyllid. When the psyllid carries the pathogenic bacteria of Huanglongbing and spreads to healthy citrus trees, the pathogenic bacteria will infect the roots and branches of citrus along with the sap flow of the tree. Citrus' own plant immune system is difficult to resist the infection of Huanglongbing pathogen. One year after the infection, the citrus tree was weakened and the yield was greatly reduced. After 3-5 years of infection with the huanglongbing pathogen, the tree body dies completely.
