[Objective]The authors identified one new disease on aubergine in facility eggplant in Heshuo County,Mongolian Autonomous Prefecture of Bayingolin,Xinjiang,and identified the species of the disease,hoping to provide a scientific basis for accurate control of the disease.[Methods]Random sampling was used to investigate and clarify the damage caused by the disease in the field,and the new disease of aubergine was identified using tissue isolation,Koch's rule,morphological observations and molecular biology to determine the taxonomic status of the pathogen.[Results]The Koch's Law results indicated that strain HR-1 was the causal agent of the disease.Strain HR-1 was more than 99.0%homologous with the reported Passalora nat-trassii.Strain HR-1(MW362742.1)was in the same branch as P.nattrassii.[Conclusion]The strain HR-1 was identified as P.nattrassii,a newly discovered disease of eggplant foliage in Xinjiang.
