Effects of Pesticides on the Diversity of Endophytic Fungi in Tea Plants

摘要: We examined the effects of agrochemicals on endophytic fungal community associated with tea plants. Endophytic fungi were isolated from four different plant tissues (bark, xylem, old leaves, new leaves) collected pesticide-treated and untreated plots. In plot, acaricides, fungicides, insecticides are typically applied 3 times each year. The infection rate was slightly lower in but difference between plots not statistically significant. Colletotrichum camelliae, Phyllosticta capitalensis, Pleosporales sp. common endophytes both Among a total 41 species, only 21 considered endophytes. pseudomajus predominant endophyte bark tissue whereas C. camelliae plot.
