摘要：

Fusarium oxysporum f.sp. niveum is reported for the first time in the Lao PDR. It was isolated from watermelons (Citrullus lanatus) in Songkhon district, Savannahkhet province following a limited ad hoc survey during January and February of 2015. Infected plants showed symptoms of wilt, vascular discolouration, necrosis in the collar region, lower stem base and upper taproot regions, and whole plant death. Identification of the pathogen was confirmed through phylogenetic analysis of the EF1-α locus and a pathogenicity test satisfying Koch’s postulates. © 2016, Australasian Plant Pathology Society Inc.
