Abstract: The paper aims to study the causes of yellow shoot disease in the navel orange orchards in Fuchuan county of Hezhou city, Guangxi. Based on daily temperature, sunshine hours, relative humidity, rainfall data from the Fuchuan Meteorological Station from 1980 to 2017, by analyzing climate statistics, and survey of the navel orange production process, we studied the correlation between current climate change in Fuchuan and the development trend of the yellow shoot disease. The results showed that the temperature change in Fuchuan in the past 38 years provided a good temperature environment for the growth of Diaphorina citri and yellow shoot disease spores; the linear increase in sunshine hours in March was beneficial to the spawning and propagation of Diaphorina citri; the annual average relative humidity change was conducive to population growth; the change of average relative humidity from June to November was beneficial to the survival and propagation of the yellow shoot disease; the increase of rainfall from June to November and October to December indirectly led to the expansion of the spread of the disease.
