【Abstract】 Arecanut yellow leaf disease is caused by phytoplasma, which has seriously affected the development of arecanut industry in Hainan. Leaves of arecanut palms infected with arecanut yellow leaf disease were sampled in the same palms in different seasons, and phytoplasma was detected using nestedPCR to analyze the year-round relationship between the arecanut yellow leaf phytoplasma and seasons..
