First report of Fusarium oxysporum causing root rot of garlic in China

Abstract

In the springs of 2020 and 2021, with a temperature of 15°C, root rot on garlic were widespread in Enshi, Hubei Province, China. Based on micro-morphological and cultural characteristics, the pathogen was identified as a Fusarium sp. Further, based on multilocus (ITS, EF-1α) phylogenic data, the strains were identified as Fusarium oxysporum. Koch’s postulates were thus fulfilled by pathogenicity tests on garlic seedlings cultured in vitro.
