This Mycosphaerella graminicola pathogen profile covers recent advances in the knowledge of this ascomycete fungus and of the disease it causes, septoria tritici blotch of wheat. Research on this pathogen has accelerated since publication of a previous pathogen profile in this journal in 2002. Septoria tritici blotch continues to have high economic importance and widespread global impact on wheat production.

Bread and durum wheat (Triticum aestivum L. and T. turgidum ssp. durum L.). Disease symptoms: Initially leaves develop a chlorotic flecking, which is followed by the development of necrotic lesions which contain brown-black pycnidia. Necrosis causes a reduction in photosynthetic capacity and therefore affects grain yield. Disease control: The disease is primarily controlled by a combination of resistant cultivars and fungicides. Rapid advances in disease control, especially in resistance breeding, are opening up new opportunities for the management of the disease.
本 Mycosphaerella graminicola 病原体简介涵盖了该子囊菌真菌及其引起的疾病——小麦叶枯病的最新研究进展。自 2002 年本刊上一篇病原体简介发表以来，对该病原体的研究进展迅速。小麦叶枯病仍然具有很高的经济重要性，并对全球小麦生产产生广泛影响。

普通小麦和硬粒小麦（Triticum aestivum L. 和 T. turgidum ssp. durum L.）。病害症状：叶片最初出现褪绿斑，随后发展为坏死斑，其中含有棕色-黑色分生孢子器。坏死导致光合作用能力下降，从而影响籽粒产量。病害防治：主要通过抗性品种和杀菌剂相结合来防治该病害。病害防治的快速进展，尤其是在抗性育种方面，为该病害的管理开辟了新的机会。
