摘要： Fusarium head blight (FHB) of wheat caused by Fusarium pseudograminearum has been increasingly prevalent in China. This study aimed to understand the prevalence and distribution of F. pseudograminearum as a pathogen causing FHB in Henan Province of China in relation to climatic conditions. A total of 1074 Fusarium isolates were obtained from diseased wheat heads in 71 fields in Henan Province during 2018-2020. F. pseudograminearum was present in 29 of the 71 fields, accounting for 17.3% of the total number of Fusarium isolates obtained. It was mainly distributed in the irrigated areas of northern Henan and the dry-farming areas of western Henan. Compared to F. graminearum, F. pseudograminearum favoured drier and colder conditions during the winter and early spring, drier conditions in the pre-anthesis period, and warmer conditions in the post-anthesis period. F. pseudograminearum in China can produce a large amount of deoxynivalenol (2.68-54.08 mg/kg), as well as a small amount of 3-acetyldeoxynivalenol (trace to 0.72 mg/kg) and zearalenone (trace to 0.25 mg/kg) in grains. Further research is needed to study potential competition among different Fusarium species in the same niche and its consequence on mycotoxin accumulation.
