Isolation, Toxigenic Potential, and Mating Type of <i>Fusarium pseudograminearum</i> Causing Wheat Crown Rot in Hebei, China.

ABSTRACT: Fusarium crown rot (FCR) is a devastating fungal disease of wheat in China that causes substantial yield losses and deterioration of grain quality. To clarify the pathogen composition and associated mycotoxin risks of FCR in Hebei Province, a comprehensive field survey was conducted during the critical growth stage from flowering to maturity (April to May) of the 2024 wheat season from 46 sites. Fungal isolates were obtained from symptomatic wheat stem bases and were identified through morphological and molecular analyses. In total, 156 Fusarium isolates were obtained, and from these isolates, 12 Fusarium species were identified based on species-specific PCR and DNA sequencing of the translation elongation factor 1-α (TEF1) loci. Of these Fusarium isolate
