Sorghum cultivation is constrained in Indonesia by pests and diseases. One such disease is tar-spot caused by the Phyllachora sp., an obligate fungal pathogen. Tar spot disease of sorghum has not been widely reported. This study reports the finding of Phyllachora species based on the morphology and molecular identification of tar spot on leaves of sorghum plants of Latu Monca and Latu Kaca local varieties.The pathogen was identified as Phyllachora species.
