大多数植物病害都是由高等植物和微生物之间微妙的相互作用组成的。酸性降水是一种环境压力，在实验条件下已显示影响某些疾病和类似现象的预期发展。从疾病三角框架的角度来看，这种影响可以通过增加植物易感性、通过改变代谢途径降低植物易感性、降低病原体活性或增加致病性来表达。气生植物部分直接暴露于降雨中，酸性降水对地上部分病原菌和病害的潜在影响是明显的。然而，土壤传播的病原体和根部疾病也可能因酸沉降导致的土壤溶液短期酸化或长期内土壤整体化学特性的逐渐变化而发生显著变化。
Most plant diseases consist of delicate interactions between higher plants and microorganisms. Acidic precipitation represents an environmental stress that has been shown to affect expected development of some diseases and similar phenomena under experimental conditions. From the perspective of the disease triangle framework, this impact may be expressed through increased plant susceptibility, decreased plant susceptibility through altered metabolic pathways, decreased pathogen activity or increased pathogenicity. Aerial plant parts are directly exposed to rainfall and the potential influence of acidic precipitation on pathogen and diseases of above ground tissues seems obvious. However, soilborne pathogens and root diseases may also be significantly altered by short-term acidification of the soil solution resulting from acid deposition, or by gradual changes in bulk soil chemical characteristics over a long period of time.
