We examined the effects of agrochemicals on the endophytic fungal community associated with tea plants. Endophytic fungi were isolated from four different tea plant tissues (bark, xylem, old leaves, new leaves) collected from pesticide-treated and untreated plots. In pesticide-treated plot, the acaricides, fungicides, and insecticides are typically applied 3 times each year. The infection rate was slightly lower in the pesticide-treated plot, but the difference between plots was not statistically significant. Colletotrichum camelliae, Phyllosticta capitalensis, and Pleosporales sp. were common endophytes in both plots. Among a total of 41 fungal species, only 21 were considered common endophytes. Colletotrichum pseudomajus was the predominant endophyte in the bark tissue in the untreated plot, whereas C. camelliae was predominant in the pesticide-treated plot. Paraphaeosphaeria neglecta and Phoma bellendis were predominant in the xylem tissues of samples from the untreated and treated plots, respectively. Colletotrichum camelliae was the most commonly found species in leaf tissues in both plots, but the colonization frequency was significantly lower in the pesticide-treated plot. Species richness was not affected by pesticide treatment. The community structure of endophytic fungi in stem tissues (bark and xylem) differed significantly between plots, but leaf tissue endophytic fungal community structure was not significantly influenced by pesticide treatment.

我们研究了农药对与茶树相关的内生真菌群落的影响。从四种不同的茶树组织（树皮、木质部、老叶、新叶）中分离出内生真菌，这些组织是从农药处理过的和未处理过的地块中收集的。杀虫剂处理地，一般每年施用3次杀螨剂、杀菌剂和杀虫剂。农药处理地块感染率略低，但地块间差异无统计学意义。Colletotrichum camelliae、Phyllosticta capitalensis和 Pleosporales sp。在两个地块中都是常见的内生菌。在总共 41 种真菌中，只有 21 种被认为是常见的内生菌。炭疽菌是未处理地块树皮组织中的主要内生菌，而C . 山茶花在农药处理的地块中占主导地位。Paraphaeosphaeria unlocka和Phoma bellendis分别在来自未处理和处理地块的样品的木质部组织中占主导地位。山茶炭疽菌是两个地块中叶组织中最常见的物种，但在农药处理地块中的定植频率明显较低。物种丰富度不受农药处理的影响。不同地块茎组织（树皮和木质部）内生真菌群落结构存在显着差异，但叶组织内生真菌群落结构不受农药处理的显着影响。
