First report of crown rot caused by Fusarium algeriense on wheat in Azerbaijan.
In June 2017, 14 fields in Ismailli and Oguz provinces, Azerbaijan, were surveyed. Diseased wheat plants (Triticum aestivum) exhibiting symptoms of crown rot including brown discoloration on the first two or three internodes of the stem were collected before maturity, at maturity, and/or after harvest. The causal pathogen was isolated and identified as Fusarium algeriense based on morphological characteristics, molecular data (sequence analysis of the internal transcribed spacer (ITS), translation elongation factor 1α (EF-1α), and the largest subunit of RNA polymerase (RPB1) loci) and pathogenicity test. This is thought to be the first report F. algeriense causing crown rot of wheat in Azerbaijan.
