Pyrenophora tritici-repentis is a plant pathogen of fungal origin, causing a disease called Helminthosporiosis, that affects mainly wheat in its more common varieties. It forms characteristic, dark, oval-shaped spots of necrotic tissue surrounded by a yellow ring^[1]. It is responsible for losses that account for up to 30% of the crop^[2], due to its effects reducing photosynthesis.
