Experimental Dataset for the First Report of Target Spot Disease of Chia (Salvia hispanica L.) Caused by Corynespora cassiicola in Bangladesh: Molecular Identification, Phylogenetic Analysis, and Fungicide Sensitivity

The corresponding nucleotide sequence datasets have been deposited in the National Center for Biotechnology Information (NCBI) GenBank database under the accession numbers listed below. Isolates Gene GeneBank accession BGECh-3 ITS PQ588139.1 BGECh-4 ITS PQ588449.1 BGECh-3 TEF-1α PQ998226.1 BGECh-4 TEF-1α PQ998227.1 Dataset Overview This repository contains the experimental datasets generated during a study documenting the first occurrence of target spot disease of chia (Salvia hispanica L.) caused by Corynespora cassiicola in Bangladesh. The data support the identification of the pathogen through morphological and molecular characterization and assessment of fungicide sensitivity of the pathogen under laboratory conditions. Morphological observations together with multilocus phylogenetic analyses of the internal transcribed spacer (ITS) and translation elongation factor 1-alpha (TEF1-α) gene sequences confirmed the pathogen as Corynespora cassiicola. The repository also includes data from in vitro fungicide sensitivity assays of seven commercially available fungicides, including information on active ingredients, modes of action, percentage mycelial growth inhibition, and EC₅₀ estimates. These datasets are provided to ensure transparency, facilitate reproducibility, and support future research on disease management and fungicide resistance monitoring of C. cassiicola.
