e0“The causal agent was identified as Didymella segeticola through morphological characterization and amplification and sequencing of the internal transcribed spacer (ITS) region, beta-tubulin ( TUB ) gene, and glyceraldehyde-3-phosphate dehydrogenase ( G3PD ) gene. Koch’s postulates, including re-isolation and identification, were performed to confirm its pathogenicity on healthy leaves.”
