Fusarium Crown Rot Pathogens Identified in Wheat Crops

Strategic Insights

— 1 min read

A recent study published in the NFS Journal identified and characterized pathogenic Fusarium species and their trichothecene genotypes in wheat crops grown in seven regions of Hebei Province, China, from 2019 to 2021. The research found that Fusarium pseudograminearum was the most detected strain, accounting for 91% of the identified strains. The study also indicated that F. pseudograminearum and F. graminearum had strong pathogenicity, while F. asiaticum and F. culmorum showed weak pathogenicity to wheat in Hebei Province.

Key Takeaways:

  • Fusarium pseudograminearum was the most detected strain, accounting for 91% of the identified strains.
  • F. pseudograminearum and F. graminearum had strong pathogenicity, while F. asiaticum and F. culmorum showed weak pathogenicity to wheat in Hebei Province.
  • The study detected 689 Fusarium strains recovered from wheat seedlings with symptomatic crown/sub-crown tissues.
  • F. pseudograminearum had detection rates of 84.50% for deoxynivalenol (DON) and other mycotoxins, including 3-acetyl-deoxynivalenol (3-AcDON) and 15-acetyl-deoxynivalenol (15-AcDON).
  • Strains of F. graminearum of the 15-AcDON chemotype were detected at 15 L-AcDON, with detection rates of 34.37%, 21.88%, 21.88%, and 18.75% in Handan, Shijiazhuang, Xingtai, and Baoding, respectively.

Statistics:

  • 91% of the identified Fusarium strains were Fusarium pseudograminearum.
  • 84.50% of F. pseudograminearum strains had detection rates of deoxynivalenol (DON) and other mycotoxins.
  • 34.37%, 21.88%, 21.88%, and 18.75% of F. graminearum strains of the 15-AcDON chemotype were detected in Handan, Shijiazhuang, Xingtai, and Baoding, respectively.
  • 689 Fusarium strains were recovered from wheat seedlings with symptomatic crown/sub-crown tissues.
