In 2022, potato plants exhibiting symptoms of stem canker were observed in commercial fields in northern Sinaloa, Mexico. Morphological characterisation of two isolates allowed the identification of Ceratobasidium sp., whereas molecular analysis using sequences of the ITS region and the rpb2 gene distinguished the isolates within the Anastomosis Group A (AG‐A). Both isolates induced symptoms of stem canker on inoculated potato plants and exhibited median EC50 values of 19.46, 5.20, 62.71 and 0.33 μg mL−1 for the fungicides thiophanate methyl, pyraclostrobin, prochloraz and penflufen, respectively. However, the two isolates differed by > 65‐fold in their EC50 value relative to pyraclostrobin. [ABSTRACT FROM AUTHOR] |
