Statistically, the citrus industry in Florida, USA affected by Huanglongbing in 2007-2008 results in total economic losses of $ 89 billion. As the world's largest orange juice producing area, in 8 months 2011, about 53.4% of citrus trees in the state of saint paul, brazil were infected with huanglongbing, and studies have shown that if citrus huanglongbing were not subject to plant quarantine control, the state would incur an economic loss of $ 89.70 billion in the future 20 years due to huanglongbing, with a sharp 45.3% reduction in citrus yield. At present, 11 of 19 provinces and 11 regions of the existing citrus cultivation in China suffer from yellow shoot disease, wherein 24 million hectares of citrus orchard in Guangdong province has annual output value of about 250 hundred million, and about 1/3 citrus orchard is infected with yellow shoot disease, and annual loss is billion.
In the last hundred years, people adopt a comprehensive prevention and control method to control the occurrence and infection of citrus greening disease, for example, disease-free nursery stocks are selected, diseased branches are cut off in time, antibiotics are injected, seriously diseased trees are dug and burned, and meanwhile, physical, chemical and biological methods are adopted to prevent and control citrus psyllids, but the method has no treatment effect on plants infected with greening disease, and also influences the food safety and greatly reduces the yield of citrus. From the 60 s in the 20 th century, Chinese scientists have studied the treatment of scion buds or seedlings with yellow dragon disease with hot and humid air, and the results show that the scion buds or seedlings can not only completely kill pathogenic bacteria in the tree bodies, but also improve the survival rate of treated seedlings. In decades, scholars at home and abroad find that the heat treatment has obvious effect of killing citrus yellow shoot pathogens through a large number of experiments.
The Chinese patent with publication number CN103404397A discloses a method for preventing and treating citrus greening disease by heat treatment, the method can reduce or eliminate the number of pathogenic bacteria in diseased trees and improve the yield and quality of citrus, but the following defects exist: (1) the time required for the heat treatment is long. In the whole treatment process, the citrus trees need to be continuously subjected to heat treatment for 2-5 hours at the temperature of 45-52 ℃, the treatment lasts for 3-4 weeks, and the efficiency is very low. (2) Is greatly influenced by natural conditions. The treatment method needs to be carried out on a sunny day with the highest daily temperature of more than 35 ℃, and for some regions, the condition is not met. (3) The economic cost is high. Each sick tree needs to be framed and covered with a plastic film, so that economic burden is heavy for farmers.
