Introduction. Septoria tritici blotch (STB), caused by Zymoseptoria tritici (Teleomorph: Mycosphaerella graminicola), is regarded as the most important disease in wheat in Europe and many other countries; yield damage from this disease can reach 40% (Selim et al., 2011).To control this pathogen, the use of fungicides, mainly the sterol 14α-demethylase inhibitors (DMI) alone or mixed with. Mycosphaerella graminicola was cultured in MYB and the other species in potato dextrose broth on a shaker (22°C, 120r.p.m.). Mycosphaerella graminicola was harvested after 5 days by centrifuging at 8000g for 2min and washed once with sterile distilled water. The other species were harvested after 5-15 days by filtration, and the water. Mycosphaerella graminicola causes Septoria tritici blotch disease of wheat (Triticum aestivum) leaves. Leaf infection involves a long (approximately 7 d) period of symptomless intercellular colonization prior to the appearance of necrotic disease lesions. Therefore, M. graminicola i Meiosis in the haploid plant-pathogenic fungus Mycosphaerella graminicola results in eight ascospores due to a mitotic division following the two meiotic divisions. The transient diploid phase allows for recombination among homologous chromosomes. However, some chromosomes of M. graminicola lack homologs and do not pair during meiosis. Becaus

Barley net blotch (BNB) caused by Pyrenophora teres, and Septoria tritici blotch (STB) caused by Mycosphaerella graminicola, are destructive cereal diseases worldwide on barley and wheat respectively. Due to the lack of highly resistant cultivars, both diseases are widely controlled using fungicides. Systemic, site-specific modern fungicides have played an essential role in disease management. BACKGROUND: The recent evolution towards resistance to azole fungicides in European populations of the wheat pathogen Mycosphaerella graminicola has been caused by the progressive accumulation of mutations in MgCYP51 gene, encoding the azole target sterol 14α-demethylase. Particular combinations of mutations have been shown specifically to. The progressive decline in the effectiveness of some azole fungicides in controlling Mycosphaerella graminicola, causal agent of the damaging Septoria leaf blotch disease of wheat, has been correlated with the selection and spread in the pathogen population of specific mutations in the M. graminicola CYP51 (MgCYP51) gene encoding the azole target sterol 14α-demethylase. Recent studies have.
