Identification and management of a novel Danshen leaf anthracnose caused by <i>Colletotrichum karstii</i> in <i>Salvia miltiorrhiza</i> Bunge in China.

ABSTRACT: Danshen (Salvia miltiorrhiza Bunge), a member of the genus Salvia within the Lamiaceae family, holds significant economic and medicinal value. Regrettably, the emergence of a novel leaf anthracnose in 2020 has significantly impacted its cultivation, leading to decreased yield and compromised quality. This newly identified pathogen was meticulously isolated from affected leaves, employing meticulous single conidia isolation techniques. Subsequent confirmation of pathogenicity was achieved through strict adherence of Koch's postulates. To ensure precise identification, morphological characteristics were supplemented with tandem sequence analysis targeting the rDNA internal transcribed spacer (ITS), β-tubulin (TUB), and histone (His3) regions.
