First report of Fusarium foetens in China on potatoes
Fusarium foetens (EPPO A2 List) is reported for the first time in China on potatoes (Solanum tuberosum). During investigations carried out in field potatoes in Laiyang city (Shandong province) in 2021, many wilted and dead potato plants were observed. It was also noted that the disease had spread rapidly, and that all infected plants had died within 2-3 weeks. Laboratory studies (morphological, molecular methods) confirmed the presence of F. foetens in symptomatic potato plants. In addition, pathogenicity tests confirmed that F. foetens was the causal agent of the disease observed. This is the first time that this pathogen, initially reported as a wilt of hybrid begonias, is reported on potatoes.
The situation of Fusarium foetens is China can be described as follows: Present, not widely distributed.
